P3 Charging Index: Comparison of the fast charging capability of various battery electric vehicles

Christian Daake, P3 automotive GmbH

The P3 Charging Index (P3CI) was developed to compare the real charging speed between various battery electric vehicles (BEVs). With the combination of the consumption and the charging curves of BEVs, the recharged kilometers can be mapped over the required charging time. This enables a accurate assessment of the fast-charging behavior of battery electric vehicles. The ideal value of the P3CI of 1.0 corresponds to the ability to recharge 300 km of range within 20 minutes, enabling a practical long-distance mobility from the customer’s perspective. The current leading edge ranges from a P3CI of 1.03 to 0.91 and the progression of BEV fast charging capability can be inferred by looking at the P3CI over time as follows: While the peak values were ~0.7 in the first release in 2019, the ideal value of 1.0 is now in 2022 exceeded for the first time.
