The new energy industry is developing rapidly, especially the energy storage industry will usher in a sustained “accelerated run” trend. The market demand for energy storage systems is increasing. The energy storage harness is an important part of the energy storage system and serves as the carrier for signal and data transmission throughout the entire energy storage industry chain.
The energy storage is mainly used to realize the imbalance between the supply and demand of energy sources by storing and releasing energy, and the energy storage systems need to be connected to each other by the energy storage wiring harness. The energy storage harnesses mainly include high-voltage harnesses for energy storage and low-voltage harnesses for energy storage. The energy storage low-voltage harness includes voltage acquisition wires, temperature sensing acquisition wires, module communication wires, main control box harness, charging cabinet harness and so on. The high-voltage harness for energy storage includes inter-box power wires, main control box power wires, convergence box power wires, DC charging sockets, AC and DC charging sockets and so on.
The energy storage power harness is an electrical harness system used to connect energy storage devices ( such as battery packs, supercapacitors, etc.) to electric vehicles, hybrid vehicles, and other energy storage systems. It is responsible for transmitting power and signals to provide support for charging and discharging, management and control of the energy storage system. The energy storage power harnesses have the following types, functional features and technical characteristics:
1.Type:
Charging harness: It is used to connect power charging equipment and the energy storage system for charging, including DC quick charging harness and AC slow charging harness.
Discharge harness: It is used to connect electric devices such as energy storage systems, electric vehicles, and hybrid vehicles for energy release and power output.
Management and control harness: It is used to connect the energy storage system and the control unit of the vehicle, transmit control signals and data, and realize the management and monitoring of the energy storage system.
2.Functional features:
High voltage capability: The energy storage power harnesses need to have a high voltage withstand capability in order to adapt to the relatively high voltage requirements in the energy storage system, such as the high voltage battery packs in electric vehicles.
High current conduction ability: The energy storage power harness needs to be able to withstand high current conduction to meet the needs of high power energy storage systems.
High temperature resistance: Due to the high temperature characteristics of the energy storage system, the harness needs to have high temperature resistance to maintain the stability and safety of the harness.
Fire resistance: The energy storage power harness needs to be fire resistant, using insulation materials and fire treatments that meet fire safety standards to reduce the risk of fire.
Vibration and shock resistance: The energy storage power harness needs to withstand vibrations and shocks during vehicle operation to ensure the reliability and safety of harness connections.
3.Technical characteristics:
Conductor and insulation materials: Choose conductor and insulation materials with high voltage insulation and high-temperature resistance, such as silicone rubber, cross-linked polyethylene (XLPE), etc.
Shielding treatment: Shield the harnesses that need to be shielded to minimize the effects of electromagnetic interference on the energy storage system and other electronic equipment.
Connectors and plugs: Using specialized connectors and plugs that meet high voltage and high current requirements ensures reliable and safe connections.
EMC (Electromagnetic Compatibility) Design: Carrying out electromagnetic compatibility design reduces the electromagnetic radiation produced by the harness and its sensitivity to external electromagnetic interference.
Reliability test: Carry out strict reliability test, including vibration test, impact test, high temperature aging test, etc., to ensure the reliability and safety of the harness in various conditions.
The energy storage power harness plays a vital role in new energy vehicles, energy storage systems and other energy storage applications. Their design and manufacture need to comply with relevant international and industry standards to ensure their quality, reliability and safety.
