The bZ4X might have a 71.4 kWh battery, but in terms of usable power it's actually 64 kWh. This is from an article from a Norwegian EV new site.
To måneder har gått. Nå vet vi mye mer om hva Toyota vil foreta seg.
Here are the changes that became known:
The battery capacity
The cars have a total battery capacity of 71.4 kWh gross. In the start-up phase, Toyota did not want to say anything about how much of this was applicable to the user, but they have been wise enough to change that. They now state that 64 kWh is the usable part of the battery capacity. The project manager for Toyota, Daisuke Ido, tells Elbil24 that they choose not to use the terminology "net capacity", as many others do, but "usable capacity". This doesn't make a big difference, so that's fine.
Among electric drivers, the instrument's display of range is often called a "guestometer". This is because the display of remaining kilometers is affected by many external factors, such as previous trips, the temperature during these trips and other things that may have changed since this was carried out. The experienced electric motorist is more interested in the percentage display, since this is an actual and concrete number that is real and reliable.
