Question to the Department for Transport:

To ask His Majesty's Government whether they will make an assessment of the implementation of a standardised battery health certification scheme for electric vehicles; and its impact on (1) consumer confidence and (2) growth in the second-hand electric vehicle market.

The battery forms a large part of an electric vehicle’s (EV) value and performance. Information about EV battery health could help consumers in the used vehicle market to make informed comparisons between vehicles and alleviate concerns about battery durability, supporting the growth of the used EV market.

The UK has worked with international partners at the United Nations Economic Commission for Europe to develop a Global Technical Regulation on EV batteries (GTR No.22). If implemented, this regulation would ensure that EVs provide easily accessible, accurate, and comparable information on the battery’s state of health. The Government is analysing options for the implementation of GTR No.22 regulations in the UK.
