Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps her Department is taking to establish a battery state-of-health certification framework for heavy goods vehicles.

My Department has worked with the United Nations Economic Commission for Europe (UNECE) to develop a Global Technical Regulation on battery durability for electrified heavy-duty vehicles (GTR 25), including heavy goods vehicles. If implemented, the regulation would set standards for the lifespan of a battery and its minimum durability. It would also ensure that battery state of health information is easily accessible, accurate and comparable.

The Government recently published its response to the consultation on updating the minimum emission standard for new road vehicles. The response committed to a further consultation on the implementation of battery state of health measures for heavy-duty vehicles in due course.
