UK battery electric bus operation: Examining battery degradation, carbon emissions and cost

Transportation Research Part D: Transport and Environment, 2022
This paper examines the impact of geographical location on the energy consumption of double deck battery electric buses operating in four UK cities. By considering seasonal variation in ambient temperature and an assumed battery degradation process, the implications on operational cost and carbon emissions were investigated.

Valuing Battery Degradation from a Battery Lessor’s Perspective

, 2015
In order to promote the market-introduction phase of electric mobility, car manufacturers will have to face the residual value risk of electric cars for consumers, particularly concerning the battery. An increasingly common trend to minimize uncertainties for the consumer, is the separate leasing of the battery.
