Product Detail
Product Description
The Cell Sampling Harness is used to collect real-time individual cell voltage and temperature signals from a multi-series lithium battery pack and transmit them to the Battery Management System (BMS).
Application
This sampling harness is designed for 14-series (14S) lithium battery packs in residential energy storage systems and is compatible with BMS units supporting cell-level monitoring and protection.
Functions
- Individual cell voltage measurement
- Cell temperature monitoring via NTC sensors
- Support for cell balancing control
- Support for over-voltage, under-voltage, and thermal protection
- Provides essential input data for SOC and SOH calculation
Design Features
- Multi-segment harness design for improved safety and signal reliability
- Low-current signal wiring optimized for voltage and temperature sensing
- Secure connector interface to prevent incorrect insertion
- Flexible cable length for easy installation inside battery packs
System Importance
The sampling harness is a critical component of the BMS system. Without correct sampling harness connection, the BMS cannot accurately monitor cell status or perform protection, balancing, and control functions.
Installation Notice
The sampling harness must be connected in a strict sequence from the lowest potential (B−) to the highest potential (B+). Incorrect wiring or connection order may result in permanent damage to the BMS.
