Batteries in battery swap stations participate in energy storage

What is battery swapping station (BSS)?

Battery Swapping Station (BSS) proposes an alternative way of refueling Electric Vehicles (EVs) that can lead towards a sustainable transportation ecosystem. BSS has significant potential to function as a grid scale energy storage. This paper provides a broad review of relation of BSS with EVs and power grid.

How much electricity can a battery swap station store?

The company estimates that 30,000 battery swap stations, each with 14-30 battery packs, can store a total of 33.6 million kWh of electricity. Combined with the 1.12 billion kWh of electricity stored by 20 million EVs served by the 30,000 battery swap stations, these distributed energy storages can respond to grid demands at any time.

Should battery swap stations participate in frequency regulation?

Enabling battery swap stations (BSSs) clusters to participate in the frequency regulation (FR) service can make full use of idle batteries to gain revenue, thereby improving the operating economy of BSSs and promoting the popularization of battery swapping mode [ 2, 3 ].

Why should you choose a battery swapping service based on location?

The optimized location of BSS lowers the cost of property rentals but also improve issues large number of users face with of the demand for battery swapping services . Optimal operation of BSS can be achieved by taking part in the day-ahead energy and reserve capacity markets. The pricing can be based on the location of BSS.

Can a battery be swapped?

In any case, a battery will always be in one of the three states to provide profitable service to the BSS. The batteries can be allowed to swap only when the SOC is above 80% and other batteries are used to supply power to the grid. A strict grid scheduling prioritizes the grid and not swapping station customer demand.

Can a battery swapping station selectively track regulation signals?

A real-time response strategy that can selectively track regulation signals. Electric vehicle battery swapping stations (BSS) have significant potential in power system frequency regulation. However, uncertainties of swapping demand and regulation signals introduce risks to operational benefits and regulation performances.
