Large Energy Storage Vehicle Equipment

EV storage needs to address complex issues related to intra-day storage demand resulting from the high penetration of variable renewable energy, and tends to facilitate a distributed energy system where end-users can support each other instead of purely relying on the main grid.

A potential capacity and cost comparison is conducted for each pathway, and it is concluded that EVs can achieve large scale energy storage effectively addressing the issue of intra-day power imbalance caused by the high penetration of variable renewable energy.

It concludes that the development of EVs is the fundamental driver for making substantial cost reductions in energy storage. Large scale investment in EVs and the purchase of these vehicles can also offer an energy storage solution in a cost-efficient way, as the potential capacity for storage increases with the number of EVs.

2.1. Energy storage potential from EVs In this paper, we argue that the energy storage potential of EVs can be realized through four pathways: Smart Charging ( SC ), Battery Swap ( BS ), Vehicle to Grid ( V2G) and Repurposing Retired Batteries ( RB ).

The energy storage potential of BS can be realized in a relatively efficient way for EV fleets, such as buses and freight vehicles.

Electric vehicles help reduce dependence on oil imports and increase national energy security. China has large amounts of renewable energy, such as solar and wind power, which can be used for electricity generation for electric vehicles.
