一．Introduction
This product is a collection instrument that specifically inspects the battery pack voltage in the DC power supply system. The internal measurement circuit is completed by high-precision A/D. Each measurement port is isolated by an optocoupler. At the same time, the equipment uses high-precision , High pressure isolation transmitter, has a complete suppression effect on the common mode and differential mode interference signals in the battery signal, ensuring good safety, stability and high precision in the measurement. Each detector can inspect 24 cells. The user can configure multiple battery inspection devices according to the needs of the battery voltage, battery charge and discharge current and battery (environment) temperature, each group can detect 384 batteries at most, and the number of single batteries can be set by the central main monitoring software; The body battery voltage can be universally tested for 2V-12V batteries. Each detector board can be connected to the central main monitor through the RS485 port. This modular bus distribution system design makes installation and maintenance work very simple and quick, and the standard MODBUS-RTU communication protocol.
