Actual case

Lithium-ion battery system features

A plurality of air-cooling devices are arranged in the battery compartment, so that the cooling air is blown along the maintenance channel through the main cooling surface of each battery module to ensure system temperature uniformity

nstall relays and fuses. When the battery system is turned off, the battery pack can be disassembled, so that the entire battery pack has no high-voltage output, which increases the safety of the battery system.

The battery modules are installed in series in the battery cabinet, and the battery cabinet is connected to the grid through a bidirectional DC module, which can perform bidirectional control of discharge and charging. The BMS provides real-time monitoring of battery status and secure management and protection of the battery system.
