Lithium Battery Pack
The 552kWh 460V 1212Ah lithium battery pack energy storage system is
composed of lithium battery modules, a BMS system, a PV charge controller or an
AC/DC charger or both, a central control unit CCU, a temperature detector, an integrated
structure and other parts. The solar panels in the system are for battery
storage and power for output. The BMS module completes the detection and
control of the voltage, current, temperature, SOC, SOH, and charging and discharging
related parameters of the power battery pack. The BMS system controls the
charging of the PV charger controller and AC/DC charger according to the battery
condition, maximizing the protection of the battery charging and discharging
performance. The Inverter converts DC to AC. Each detector is used to monitor the
ambient temperature in real time to ensure the safety of the system.
components, modular architecture, easy to expand

software and hardware protection, with alarm protection and automatic
diagnostic functions, improve the protection strategy to ensure safe and efficient
operation of the system.
The system communicates
with the monitoring platform in real time through RS232, CAN communication interface,
and reports various records in time to ensure real-time monitoring of the battery
pack by the monitoring platform.
The PV charge controller
adopts three charging stages (buck charging, equalize charging, and float
charging) which can maximize the utilization of PV modules and batteries.
An AC/DC charger with
an LCD touch screen display which can display fault code and KWH, the output
voltage parameter is adjustable, can set the charging time, can work in parallel
with CAN communication port.
Colorful LCD display
to show all module working information and status.
