Energy storage battery swap station

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 does a battery swapping station work?

This is used in cars with bottom-mounted batteries. The automobile is placed on a raised platform by the swapping station, and the batteries are changed from the bottom using an automation arm and other peripherals that are often located below ground. The station is constructed to raise the car on an elevated platform.

Are battery swapping stations better than EV charging stations?

This paper discusses the concept of battery swapping stations (BSS) for electric vehicles (EVs). This concept is superior to the EV charging station when compared in many aspects, like the time the EV driver needs to spend at the EV charging station.

What is battery swapping income?

Among them, the battery swapping income is the fees paid by electric vehicle users to BSS for battery swapping. The battery charging and discharging income includes the cost of BSS purchasing energy from the power system to charge the batteries and the benefits of transmitting power to the power system.

How to calculate battery swapping cost?

The swapping cost is determined according to the following formula: (1) where is the swapping cost of the th EVs. and are the cost coefficients of swapping battery SOC and SOH, respectively. and are the state of charge before and after battery swapping, respectively. and are the state of health before and after battery swapping, respectively.

What are the advantages of BSS EV battery swap?

The EV battery has energy storage characteristics, so that it can be used as an energy storage device to transmit energy to the power system during peak load periods. Consequently, the BSS provides auxiliary services for the power system while providing battery swaps for EVs, and it is conducive to give full play to the advantages of BSS.
