24-channel battery inspection unit module Voltage and current acquisition module Multi-channel battery detection unit module
I. Overview The 24-channel intelligent battery inspection unit (hereinafter referred to as the battery inspection unit), the main function is to perform real-time online tour detection on the battery voltage of the series battery pack. The battery inspection unit is mainly used for real-time voltage monitoring of DC power supply and UPS power supply battery packs in power plants, substations or other industries, so that the failed battery can be found in time, the power supply can be safely operated, and the reliability and automation of the system can be improved. degree.
Second, function and characteristics ■ Real-time monitoring of the voltage of each cell in the battery pack in real time;
■ Online real-time measurement of battery pack charge and discharge current
■ Each individual battery inspection unit supports detection of 24 series batteries, which can support cascading between 247 individual battery inspection units;
■ The battery collection channel is isolated by optocoupler, no noise, no interference, long life; the internal core circuit of the inspection unit is completely isolated from the battery circuit under test, which greatly enhances the anti-interference ability and improves the reliability of the instrument.
■ Isolated RS-485 communication interface with protection, using MODBUS communication protocol, can realize data bus communication.
■ Measuring voltage range 0~15V, compatible with 2V, 6V, 12 batteries commonly used in the market.
■ The battery acquisition input uses a protection circuit to prevent the battery from damaging internal circuit components.
■ Support device address dialing can be set.
