(22)Vehicles with traction batteries, including plug-in hybrids and battery electric vehicles, contribute to the decarbonisation of the road transport sector. In order to gain and increase consumer trust in such vehicles, they should be performant and durable. It is therefore important to require that traction batteries retain a good part of their initial capacity after many years of use. Such a requirement would be of particular importance to buyers of second-hand electric vehicles given that it would ensure that the vehicle would continue to perform as expected. Monitors of the state of health of traction batteries should therefore be required for all vehicles that use traction batteries. In addition, minimum performance requirements for battery durability of passenger cars and light commercial vehicles should be introduced, taking into account UN Global Technical Regulation No 22.
