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.
Design of Energy Storage Charging Pile Equipment 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.
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 user can control the energy storage charging pile device through the mobile terminal and the Web client, and the instructions are sent to the energy storage charging pile device via the NB network. The cloud server provides services for three types of clients.
Instructions for Charging Pile-V1.3.0: Power Output Mode: Can be switched between intelligent mode and priority mode. In intelligent mode, the charging pile power is equally distributed between the two vehicle connectors.
Due to the urgency of transaction processing of energy storage charging pile equipment, the processing time of the system should reach a millisecond level. 3.3. Overall Design of the System
