Since the first week of April 2022 I have (finally!) changed my company car from a plug-in hybrid to a fully electic car. My new ride, for the next two years, is a BMW i4 M50 in Aventurine Red metallic. An ellegant car with very deep and memorable color, insanely powerful (544 hp/795 Nm), sub-4 second 0-100 km/h, large 84 kWh battery (80 kWh usable), charging up to 210 kW, top speed of 225 km/h and also very efficient (which came out best in this trip) with WLTP range of 510 km and EVDB real range of 435 km. The car also has performance tyres (Hankook Ventus S1 evo3 245/45R18 100Y XL in front and 255/45R18 103Y XL in rear all at recommended 2.5 bar) that have reduced efficiency. So I wanted to document and describe how was it for me to travel ~2000 km (one way) with this, electric, car from south of Germany to north of Latvia. I have done this trip many times before since I live in Germany now and travel back to my relatives in Latvia 1-2 times per year. This was the first time I made this trip in an electric car. And as this trip includes both travelling in Germany (where BEV infrastructure is best in the world) and across Eastern/Northen Europe, I believe that this can be interesting to a few people out there. Normally when I travelled this trip with a gasoline/diesel car I would normally drive for two days with an intermediate stop somewhere around Warsaw with about 12 hours of travel time in each day. This would normally include a couple bathroom stops in each day, at least one longer lunch stop and 3-4 refueling stops on top of that. Normally this would use at least 6 liters of fuel per 100 km on average with total usage of about 270 liters for the whole trip (or about 540 just in fuel costs, nowadays). My (personal) quirk is that both fuel and recharging of my (business) car inside Germany is actually paid by my employer, so it is useful for me to charge up (or fill up) at the last station in Gemany before driving on. The plan for this trip was made in a similar way as when travelling with a gasoline car: travelling as fast as possible on German Autobahn network to last chargin stop on the A4 near G rlitz, there charging up as much as reasonable and then travelling to a hotel in Warsaw, charging there overnight and travelling north towards Ionity chargers in Lithuania from where reaching the final target in north of Latvia should be possible. How did this plan meet the reality? Travelling inside Germany with an electric car was basically perfect. The most efficient way would involve driving fast and hard with top speed of even 180 km/h (where possible due to speed limits and traffic). BMW i4 is very efficient at high speeds with consumption maxing out at 28 kWh/100km when you actually drive at this speed all the time. In real situation in this trip we saw consumption of 20.8-22.2 kWh/100km in the first legs of the trip. The more traffic there is, the more speed limits and roadworks, the lower is the average speed and also the lower the consumption. With this kind of consumption we could comfortably drive 2 hours as fast as we could and then pick any fast charger along the route and in 26 minutes at a charger (50 kWh charged total) we'd be ready to drive for another 2 hours. This lines up very well with recommended rest stops for biological reasons (bathroom, water or coffee, a bit of movement to get blood circulating) and very close to what I had to do anyway with a gasoline car. With a gasoline car I had to refuel first, then park, then go to bathroom and so on. With an electric car I can do all of that while the car is charging and in the end the total time for a stop is very similar. Also not that there was a crazy heat wave going on and temperature outside was at about 34C minimum the whole day and hitting 40C at one point of the trip, so a lot of power was used for cooling. The car has a heat pump standard, but it still was working hard to keep us cool in the sun. The car was able to plan a charging route with all the charging stops required and had all the good options (like multiple intermediate stops) that many other cars (hi Tesla) and mobile apps (hi Google and Apple) do not have yet. There are a couple bugs with charging route and display of current route guidance, those are already fixed and will be delivered with over the air update with July 2022 update. Another good alterantive is the ABRP (A Better Route Planner) that was specifically designed for electric car routing along the best route for charging. Most phone apps (like Google Maps) have no idea about your specific electric car - it has no idea about the battery capacity, charging curve and is missing key live data as well - what is the current consumption and remaining energy in the battery. ABRP is different - it has data and profiles for almost all electric cars and can also be linked to live vehicle data, either via a OBD dongle or via a new Tronity cloud service. Tronity reads data from vehicle-specific cloud service, such as MyBMW service, saves it, tracks history and also re-transmits it to ABRP for live navigation planning. ABRP allows for options and settings that no car or app offers, for example, saying that you want to stop at a particular place for an hour or until battery is charged to 90%, or saying that you have specific charging cards and would only want to stop at chargers that support those. Both the car and the ABRP also support alternate routes even with multiple intermediate stops. In comparison, route planning by Google Maps or Apple Maps or Waze or even Tesla does not really come close. After charging up in the last German fast charger, a more interesting part of the trip started. In Poland the density of high performance chargers (HPC) is much lower than in Germany. There are many chargers (west of Warsaw), but vast majority of them are (relatively) slow 50kW chargers. And that is a difference between putting 50kWh into the car in 23-26 minutes or in 60 minutes. It does not seem too much, but the key bit here is that for 20 minutes there is easy to find stuff that should be done anyway, but after that you are done and you are just waiting for the car and if that takes 4 more minutes or 40 more minutes is a big, perceptual, difference. So using HPC is much, much preferable. So we put in the Ionity charger near Lodz as our intermediate target and the car suggested an intermediate stop at a Greenway charger by Katy Wroclawskie. The location is a bit weird - it has 4 charging stations with 150 kW each. The weird bits are that each station has two CCS connectors, but only one parking place (and the connectors share power, so if two cars were to connect, each would get half power). Also from the front of the location one can only see two stations, the otehr two are semi-hidden around a corner. We actually missed them on the way to Latvia and one person actually waited for the charger behind us for about 10 minutes. We only discovered the other two stations on the way back. With slower speeds in Poland the consumption goes down to 18 kWh/100km which translates to now up to 3 hours driving between stops. At the end of the first day we drove istarting from Ulm from 9:30 in the morning until about 23:00 in the evening with total distance of about 1100 km, 5 charging stops, starting with 92% battery, charging for 26 min (50 kWh), 33 min (57 kWh + lunch), 17 min (23 kWh), 12 min (17 kWh) and 13 min (37 kW). In the last two chargers you can see the difference between a good and fast 150 kW charger at high battery charge level and a really fast Ionity charger at low battery charge level, which makes charging faster still. Arriving to hotel with 23% of battery. Overnight the car charged from a Porsche Destination Charger to 87% (57 kWh). That was a bit less than I would expect from a full power 11kW charger, but good enough. Hotels should really install 11kW Type2 chargers for their guests, it is a really significant bonus that drives more clients to you. The road between Warsaw and Kaunas is the most difficult part of the trip for both driving itself and also for charging. For driving the problem is that there will be a new highway going from Warsaw to Lithuanian border, but it is actually not fully ready yet. So parts of the way one drives on the new, great and wide highway and parts of the way one drives on temporary roads or on old single lane undivided roads. And the most annoying part is navigating between parts as signs are not always clear and the maps are either too old or too new. Some maps do not have the new roads and others have on the roads that have not been actually build or opened to traffic yet. It's really easy to loose ones way and take a significant detour. As far as charging goes, basically there is only the slow 50 kW chargers between Warsaw and Kaunas (for now). We chose to charge on the last charger in Poland, by Suwalki Kaufland. That was not a good idea - there is only one 50 kW CCS and many people decide the same, so there can be a wait. We had to wait 17 minutes before we could charge for 30 more minutes just to get 18 kWh into the battery. Not the best use of time. On the way back we chose a different charger in Lomza where would have a relaxed dinner while the car was charging. That was far more relaxing and a better use of time. We also tried charging at an Orlen charger that was not recommended by our car and we found out why. Unlike all other chargers during our entire trip, this charger did not accept our universal BMW Charging RFID card. Instead it demanded that we download their own Orlen app and register there. The app is only available in some countries (and not in others) and on iPhone it is only available in Polish. That is a bad exception to the rule and a bad example. This is also how most charging works in USA. Here in Europe that is not normal. The normal is to use a charging card - either provided from the car maker or from another supplier (like PlugSufring or Maingau Energy). The providers then make roaming arrangements with all the charging networks, so the cards just work everywhere. In the end the user gets the prices and the bills from their card provider as a single monthly bill. This also saves all any credit card charges for the user. Having a clear, separate RFID card also means that one can easily choose how to pay for each charging session. For example, I have a corporate RFID card that my company pays for (for charging in Germany) and a private BMW Charging card that I am paying myself for (for charging abroad). Having the car itself authenticate direct with the charger (like Tesla does) removes the option to choose how to pay. Having each charge network have to use their own app or token bring too much chaos and takes too much setup. The optimum is having one card that works everywhere and having the option to have additional card or cards for specific purposes. Reaching Ionity chargers in Lithuania is again a breath of fresh air - 20-24 minutes to charge 50 kWh is as expected. One can charge on the first Ionity just enough to reach the next one and then on the second charger one can charge up enough to either reach the Ionity charger in Adazi or the final target in Latvia. There is a huge number of CSDD (Road Traffic and Safety Directorate) managed chargers all over Latvia, but they are 50 kW chargers. Good enough for local travel, but not great for long distance trips. BMW i4 charges at over 50 kW on a HPC even at over 90% battery state of charge (SoC). This means that it is always faster to charge up in a HPC than in a 50 kW charger, if that is at all possible. We also tested the CSDD chargers - they worked without any issues. One could pay with the BMW Charging RFID card, one could use the CSDD e-mobi app or token and one could also use Mobilly - an app that you can use in Latvia for everything from parking to public transport tickets or museums or car washes. We managed to reach our final destination near Aluksne with 17% range remaining after just 3 charging stops: 17+30 min (18 kWh), 24 min (48 kWh), 28 min (36 kWh). Last stop we charged to 90% which took a few extra minutes that would have been optimal. For travel around in Latvia we were charging at our target farmhouse from a normal 3 kW Schuko EU socket. That is very slow. We charged for 33 hours and went from 17% to 94%, so not really full. That was perfectly fine for our purposes. We easily reached Riga, drove to the sea and then back to Aluksne with 8% still in reserve and started charging again for the next trip. If it were required to drive around more and charge faster, we could have used the normal 3-phase 440V connection in the farmhouse to have a red CEE 16A plug installed (same as people use for welders). BMW i4 comes standard with a new BMW Flexible Fast Charger that has changable socket adapters. It comes by default with a Schucko connector in Europe, but for 90 one can buy an adapter for blue CEE plug (3.7 kW) or red CEE 16A or 32A plugs (11 kW). Some public charging stations in France actually use the blue CEE plugs instead of more common Type2 electric car charging stations. The CEE plugs are also common in camping parking places. On the way back the long distance BEV travel was already well understood and did not cause us any problem. From our destination we could easily reach the first Ionity in Lithuania, on the Panevezhis bypass road where in just 8 minutes we got 19 kWh and were ready to drive on to Kaunas, there a longer 32 minute stop before the charging desert of Suwalki Gap that gave us 52 kWh to 90%. That brought us to a shopping mall in Lomzha where we had some food and charged up 39 kWh in lazy 50 minutes. That was enough to bring us to our return hotel for the night - Hotel 500W in Strykow by Lodz that has a 50kW charger on site, while we were having late dinner and preparing for sleep, the car easily recharged to full (71 kWh in 95 minutes), so I just moved it from charger to a parking spot just before going to sleep. Really easy and well flowing day. Second day back went even better as we just needed an 18 minute stop at the same Katy Wroclawskie charger as before to get 22 kWh and that was enough to get back to Germany. After that we were again flying on the Autobahn and charging as needed, 15 min (31 kWh), 23 min (48 kWh) and 31 min (54 kWh + food). We started the day on about 9:40 and were home at 21:40 after driving just over 1000 km on that day. So less than 12 hours for 1000 km travelled, including all charging, bio stops, food and some traffic jams as well. Not bad. Now let's take a look at all the apps and data connections that a technically minded customer can have for their car. Architecturally the car is a network of computers by itself, but it is very secured and normally people do not have any direct access. However, once you log in into the car with your BMW account the car gets your profile info and preferences (seat settings, navigation favorites, ...) and the car then also can start sending information to the BMW backend about its status. This information is then available to the user over multiple different channels. There is no separate channel for each of those data flow. The data only goes once to the backend and then all other communication of apps happens with the backend. First of all the MyBMW app. This is the go-to for everything about the car - seeing its current status and location (when not driving), sending commands to the car (lock, unlock, flash lights, pre-condition, ...) and also monitor and control charging processes. You can also plan a route or destination in the app in advance and then just send it over to the car so it already knows where to drive to when you get to the car. This can also integrate with calendar entries, if you have locations for appointments, for example. This also shows full charging history and allows a very easy export of that data, here I exported all charging sessions from June and then trimmed it back to only sessions relevant to the trip and cut off some design elements to have the data more visible. So one can very easily see when and where we were charging, how much power we got at each spot and (if you set prices for locations) can even show costs. I've already mentioned the Tronity service and its ABRP integration, but it also saves the information that it gets from the car and gathers that data over time. It has nice aspects, like showing the driven routes on a map, having ways to do business trip accounting and having good calendar view. Sadly it does not correctly capture the data for charging sessions (the amounts are incorrect). Update: after talking to Tronity support, it looks like the bug was in the incorrect value for the usable battery capacity for my car. They will look into getting th eright values there by default, but as a workaround one can edit their car in their system (after at least one charging session) and directly set the expected battery capacity (usable) in the car properties on the Tronity web portal settings. One other fun way to see data from your BMW is using the BMW integration in Home Assistant. This brings the car as a device in your own smart home. You can read all the variables from the car current status (and Home Asisstant makes cute historical charts) and you can even see interesting trends, for example for remaining range shows much higher value in Latvia as its prediction is adapted to Latvian road speeds and during the trip it adapts to Polish and then to German road speeds and thus to higher consumption and thus lower maximum predicted remaining range. Having the car attached to the Home Assistant also allows you to attach the car to automations, both as data and event source (like detecting when car enters the "Home" zone) and also as target, so you could flash car lights or even unlock or lock it when certain conditions are met. So, what in the end was the most important thing - cost of the trip? In total we charged up 863 kWh, so that would normally cost one about 290 , which is close to half what this trip would have costed with a gasoline car. Out of that 279 kWh in Germany (paid by my employer) and 154 kWh in the farmhouse (paid by our wonderful relatives :D) so in the end the charging that I actually need to pay adds up to 430 kWh or about 150 . Typically, it took about 400 in fuel that I had to pay to get to Latvia and back. The difference is really nice! In the end I believe that there are three different ways of charging:

• incidental charging - this is wast majority of charging in the normal day-to-day life. The car gets charged when and where it is convinient to do so along the way. If we go to a movie or a shop and there is a chance to leave the car at a charger, then it can charge up. Works really well, does not take extra time for charging from us.
• fast charging - charging up at a HPC during optimal charging conditions - from relatively low level to no more than 70-80% while you are still doing all the normal things one would do in a quick stop in a long travel process: bio things, cleaning the windscreen, getting a coffee or a snack.
• necessary charging - charging from a whatever charger is available just enough to be able to reach the next destination or the next fast charger.

The last category is the only one that is really annoying and should be avoided at all costs. Even by shifting your plans so that you find something else useful to do while necessary charging is happening and thus, at least partially, shifting it over to incidental charging category. Then you are no longer just waiting for the car, you are doing something else and the car magically is charged up again. And when one does that, then travelling with an electric car becomes no more annoying than travelling with a gasoline car. Having more breaks in a trip is a good thing and makes the trips actually easier and less stressfull - I was more relaxed during and after this trip than during previous trips. Having the car air conditioning always be on, even when stopped, was a godsend in the insane heat wave of 30C-38C that we were driving trough. Final stats: 4425 km driven in the trip. Average consumption: 18.7 kWh/100km. Time driving: 2 days and 3 hours. Car regened 152 kWh. Charging stations recharged 863 kWh. Questions?
