The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period. In this section, the energy storage charging pile device is designed as a whole.
The heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system. At present, the typical high-power direct current EV charging pile available in the market is about 150 kW with a heat generation power from 60 W to 120 W ( Ye et al., 2021 ).
On the one hand, the energy storage charging pile interacts with the battery management system through the CAN bus to manage the whole process of charging.
The new energy storage charging pile system for EV is mainly composed of two parts: a power regulation system and a charge and discharge control system. The power regulation system is the energy transmission link between the power grid, the energy storage battery pack, and the battery pack of the EV.
