Norway has, as you probably saw in the 2021 Superbowl ad with Will Ferrell, the highest density of EV in the world. Today app. 20 % of the car fleet. Mainly due to the taxacion policy, EVs are tax free, making them app. 30-40 % cheaper than a similar model fossil fuel car. Last month almost 70 % of all new sold cars were fully electric or chargeable hybrids. This fall, the Tesla Y is the overall most sold car model, last year was The Audi e-tron, the year before, the Tesla 3. Model S also sold in large numbers the last 5 years. When it comes to charging stations, we have today 1.328 charging stations for a population of 5,5 millions. (https://ladekart.elbil.no/more) The number of EVs are growing faster than the number of public chargers being erected. Today we have 19 EVs per charging post, in 2017 the number was 13. Vans, trucks and even ferries are being electrified quickly now.
But, we have several challenges:
1. Range
Most EVs being tested in real life, show a shorter range than what the suppliers advertise. Even measured by WELP. A test in Norw. Car Owners Ass. shows that some have up to 25% less range in summer-, and 30% in wintertime, than advertised. This test is based on a long day trip in average Norw. landscape. Check (https://motor.no/bil/sjekk-motors-rekkevidde-resultater-bilmodell-for-bilmodell/202424) Sorry, no english version.
Teslas have good power efficiency (i.e. kWh per 100 km), mostly due to low air drag (Cd-value). Tesla mod 3 burns typical 11,9 kWh/km in summer, where as the heaviest Audi e-tron 55 burns 20,3 kWh. Rivians, being even higher and heavier, must burn even more. Heavy cars need stiffer tiresides, which also increases rolling resistance, and range. I haven’t seen the burn rate for the Rivians yet, I expect numbers will come when they start rolling. The higher burn rate figures for winter, are caused by power consumption for internal heating, warm seats, defrost, etc. Manufacturers as Tesla, have included heat pumps in their recent models for Scandinavia. A heat pump takes heat from the air, and saves battery power. I don’t know if Rivian includes this. All in all, I’d be surprised if the announced ranges for the different battery pacs are correct in reality. Towing a camper gives extended air drag and is extra weight uphill. Check the consumption thoroughly, before you plan long trips.
2. Charging
As mentioned, we have a pretty good number of chargers, especially considering that folks necessarily have their own chargers at home, and many can charge at work. Still, we experience certain challenges. You can plan your trip using an app that calculates range and consumption, and points out the suitable charging stations for your trip. However, many discover that some chargers are out of order, and some times we see long queues and waiting lines. Many (elder) chargers supply only low effects. Not many can provide 100 or 150 kW or more so far. Rumors also say that when all chargers at a station are in use simultaneously, the Voltage drops, and charging takes longer. To compensate, the station owners encourages you to only charge only up to 80%, as the last 20% takes much longer time per kWh. Tesla also recommends to not charge more than 80%, to prolong battery life. People also report that apps don’t always work for chargers, and payment. We still haven’t seen chargers where you can pay by credit card, like when you fuel. The power at the charger is also much more expensive per kWh, than you pay for electricity at home. Tesla chargers are many, but won’t charge others than Teslas.
3. Home charging
The amount of power your house can supply for a car charger, is probably limited. Don’t expect any quick charge. We are now encouraged to charge only late at knight, to save the powerlines in daytime. Living in a condominium, with a common parking lot, has caused conflicts. The power transformer for the building has a maximum outlet, and can only provide a limited number of extra car chargers. If you are a late EV buyer, you risk getting a NO when you apply the condo for a charger.
Hence, the experience is: Your Rivian most likely will run shorter than what Rivian advertises, and charging is often a disappointment, it takes longer than assumed, and you have to have a plan B, in case the charging station can’t provide the expected charging according to your plan. Your app doesn’t tell if chargers are out of order, or if you are faced with long waiting lines.
The conclusion is: Get the MAX PACK !
Range anxiety is frustrating, and it`s annoying driving the last 50 miles home in 40 miles/h and close behind a slow 18 wheeler to save power and hoping you make it.
