The primary function of charge relay is for signal detection, transmission, conversion or disposal. The circuit current it switches on and off is generally small, and is generally used in control circuits to control weak signals. Its primary function is to turn on or off the main circuit.
A typical BMS consists of various components, including voltage and current sensors, temperature sensors, control circuitry, and communication interfaces. These components work together to ensure the safe and efficient operation of the battery pack.
One of the key components of a BMS is the schematic, which provides a detailed representation of the system’s architecture, including the various sensors, modules, and circuits involved. The battery management system schematic serves as a roadmap for engineers and technicians involved in the design and implementation process.
The BMS should incorporate a cell balancing circuitry that redistributes charge between cells as needed to maintain balance. This can be achieved using techniques such as active or passive cell balancing. Temperature is another critical parameter to monitor in a battery pack.
Voltage relays: mainly used as overvoltage, undervoltage and zero voltage protection of the battery. The safety of high voltage is an important factor to ensure the safety of the lifepo4 battery, and the relay must be disconnected in an emergency to ensure that the power battery will not output power. 2. The role of the charge relay
