Battery Signal Acquisition Harness Manufacturer & Supplier
Battery Signal Acquisition Line Overview
A battery signal acquisition harness is a critical wiring assembly designed specifically for new energy storage battery systems. Its core purpose is to accurately collect data on individual cell voltages, module temperatures, equalization status, and communication signals (CAN/LIN) of the energy storage battery pack. This includes lithium battery and lithium iron phosphate battery configurations. Manufactured by Dongguan Songyuan Technology Co., Ltd., the harness supports various BMS platforms and mainstream BMS interfaces, ensuring reliable signal matching across different energy storage architectures.
Because energy storage systems depend on precise battery management, the quality and design of the signal acquisition harness directly influence data integrity. The assembly is engineered for precise data collection with zero deviation, and it delivers strong anti-interference capability that adapts to various energy storage environments. Whether the battery pack operates in a utility-scale container, a commercial cabinet, or an outdoor installation, the harness helps maintain stable communication between the battery modules and the BMS.

Customization & Ordering
Customization is central to this battery signal acquisition harness. The BMS interface pin definition, battery pack voltage level, and module quantity can be specified to match various BMS platforms. Cable length, conductor and sheath material, terminal and connector type, shielding and protection level, function extensions, marking, and packaging can all be tailored. For example, silicone sheath is available for low-temperature environments below -40 degC, PTFE for corrosive conditions, and PVC for standard scenarios. Double-layer shielding is recommended near inverters or frequency converters, and IP67 protection can be specified for outdoor energy storage equipment. Explosion-proof connectors are available for high-voltage energy storage battery packs above 600V.
For standard specifications, prototyping is stated at 48 hours. Flexible order quantities are stated as follows: prototype runs from 100 pcs, and volume production from 1,000 pcs. Mass production of lines of this type generally takes 15–25 days from order confirmation; the exact schedule is confirmed with each quote. Free laser marking is available for bulk orders of 50 sets or more. Anti-static packaging is optional for precision energy storage BMS matching.
