Introduction
The 51.2V200Ah - HV energy storage device is designed for residential use with short - term backup. It's not suitable for powering life - sustaining medical equipment.The system is integrated with a built-in wireless Wi-Fi module, facilitating remote monitoring and debugging through mobile devices. On the exterior, it features a touch-color display, status indicators, and charge level indicators, enabling users to clearly assess the status of the energy storage system. Additionally, each battery unit is equipped with a cooling fan that automatically activates to dissipate heat under high-temperature conditions.

HV BCU
The BCU (Battery Control Unit) consists of a main BMS (Battery Management System), a DC fuse, a soft-start circuit, a charging circuit, a discharging circuit, a 24VDC/DC power module, a cut-off protection switch, a touch-color screen, a wireless Wi-Fi module, and a status indicator panel. The BMS within the battery module collects data on battery voltage and temperature, and uploads this data to the main BMS via the internal CAN (Controller Area Network). The BCU of the BMS controls the charging voltage/current and discharging voltage/current.

The battery module comprises a battery cell energy storage unit, a cooling fan, and a subordinate BMS (Battery Management System). The subordinate BMS collects and transmits the battery voltage and temperature of the battery cells in real - time, and conducts internal communication with the main BMS. When the energy storage system reaches the set temperature, the main BMS controls the cooling fan to operate for temperature adjustment.
