Like all batteries, the cells that power an EV will degrade over time. However, our data shows that while battery degradation in EVs is an issue, it''s not as bad as you might think. In our survey, we asked over 3,000* owners of EVs to tell us by how much the range of

The most comprehensive way to measure battery degradation is to complete an energy capacity test. The system is charged to 100% SoC and then discharged continuously at a set power until 0% SoC is reached (i.e. 1-hour discharge at rated power from 100%-0% SoC).
The battery power P b, t can also be defined according to Equation based on the battery pack voltage and current, which are affected by battery degradation. In order to simulate the performance at different ageing levels, a battery model that includes the degradation should be employed, as presented in Section 2.3 .
