On the other hand, it will cause the peak overlapping peak if we access the EV for charging at the peak of electricity consumption. In order to reduce the peak and valley difference, give full play to the role of EV batteries, vehicle-to-grid (V2G) technology came into being.

Can EV batteries supply short-term storage facilities?

For higher vehicle utilisation, neglecting battery pack thermal management in the degradation model will generally result in worse battery lifetimes, leading to a conservative estimate of electric vehicle lifetime. As such our modelling suggests a conservative lower bound of the potential for EV batteries to supply short-term storage facilities.

Should EV batteries be used as stationary storage?

Low participation rates of 12%–43% are needed to provide short-term grid storage demand globally. Participation rates fall below 10% if half of EV batteries at end-of-vehicle-life are used as stationary storage. Short-term grid storage demand could be met as early as 2030 across most regions.

Our estimates are generally conservative and offer a lower bound of future opportunities. Renewable energy and electric vehicles will be required for the energy transition, but the global electric vehicle battery capacity available for grid storage is not constrained.

Do battery electric vehicles and photovoltaics increase electricity costs?

Battery electric vehicle (BEV) and photovoltaic (PV) electricity adoption increases in many climate change mitigation scenarios, yet large-scale deployment of these technologies, if left unmanaged, can raise electricity costs by increasing peak evening electricity demand and causing overgeneration of electricity during midday.
