A cold battery will not hold 21kWh usable, and I use a rule of thumb of each 4F below 70F equals 1% loss in capacity. To find out, we grouped the vehicles based on the following climate conditions: As illustrated below, vehicles driven in hot climates showed a notably faster rate of decline than those driven in moderate climates. This is not degradation of the battery, just how Li ion batteries perform at different temperatures. What program can measure SOH (or kWh) high-voltage battery? Electric vehicle battery health has a direct impact not only on maximum usable range over time but also the vehicle's residual value. According to a recent survey, the average EV owner only notices a 2% battery decline after three years of driving and a 7% decline after six years on the road. Geotab has developed a free tool to compare the average battery degradation over time for different vehicle makes and model years. Let’s compare a vehicle with a liquid cooling system to one with a passive air cooling system: the 2015 Tesla Model S and the 2015 Nissan Leaf, respectively. While this tool shows more or less linear degradation, as a general rule, EV batteries are expected to decline non-linearly: an initial drop, which then continues to decline but at a far more moderate pace.

Found insidePrachi Patel, "How Inexpensive Must Energy Storage Be for Utilities to Switch to 100 Percent Renewables? While the larger buffers mean less energy for driving, it should result in a longer lasting battery pack. Given the larger SOC buffers, liquid thermal management, and dynamic (decreasing) buffer size, slower than average degradation rates should be expected on the Volt. For instance, a 30F battery would hold 70 - 30 = 40F difference divided by 4 equals 10% loss, or 18.9kWh. I asked about a program that can show the capacity of a high voltage battery. "There is a pervasive myth about the speed of EV battery pack degradation that is causing a psychological barrier to EV entry," says Zero Carbon World Trustee, Dean Fielding. That has been supported by several high mileage Tesla's, like this Model S that recently passed 1,000,000km. Get the most out of your telematics platform with our product guide.
