A marine battery module with leakage and smoke detection functions

Abstract

This utility model discloses a marine battery module with leakage and smoke detection functions, including several battery packs, a high-voltage interlock device, and a safety detection board disposed within a housing. The high-voltage interlock device is connected in series in the high-voltage output circuit of the battery packs. The safety detection board is equipped with a smoke detection sensor, a leakage detection sensor, and a high-voltage leakage detection (HVIL) detector. All of these sensors, including the smoke detection sensor, the leakage detection sensor, the HVIL detector, and the high-voltage interlock device, are connected to a battery management system. This utility model enables real-time monitoring of leakage, smoke, and high-voltage interlock status. Upon detecting an anomaly, it quickly cuts off the high-voltage output circuit and accurately locates the fault, preventing the fault from escalating and reducing the risk of battery thermal runaway, short circuit, and fire.
