Overview

In-depth Product Details & Applications

Solution Overview

The energy storage BMS system needs to collect voltage and temperature data from each battery cell string in real time. As the key node between the sampling harness and the main control board, the reliability of the connector directly affects the safe operation of the battery system. This solution uses high-quality connectors that have undergone strict certification to provide an all-weather reliable signal acquisition channel for the energy storage BMS.

Main Application Areas

Energy storage BMS main control: cell voltage sampling harness interface, NTC temperature sensor connection, CAN/RS485 communication bus
Battery module: cell sampling harness connection within the module, balancing control harness, module temperature acquisition
High-voltage control box: contactor control signal, pre-charge control, current sensor interface, insulation detection
Energy storage power station: cluster-level BMS communication connection, environmental control monitoring interface, fire linkage signal, total voltage/current detection

Solution Advantages

The sampling harness adopts a dual-wire redundant design, so a single point of failure does not affect the normal operation of the BMS; the connector CPA locking structure prevents loosening due to vibration; the entire series has passed UL 1977/UL 4128 energy storage system component certification.
