Electric Vehicle Power Solution

In electric vehicles, the high-voltage DC battery is the primary source of power for driving the electric motor. Therefore, ensuring the safety and reliability of the battery system is of utmost importance. High-voltage DC relays and fuses are key components in ensuring the safety of the battery system, as they can help prevent issues such as overcurrent, short circuit, and overtemperature.


High-voltage DC relays are essential components in the electrical systems of new energy vehicles, helping to ensure the safe, efficient, and reliable operation of the vehicle.

New Energy Vehicle Battery Management System 1

Battery Pack Control

Control the charging and discharging of the battery pack. They can help to prevent overcharging, which can damage the battery, and can also prevent over-discharging, which can reduce the lifespan of the battery.

Electric Motor Control

Control the flow of current to the electric motor. By turning the motor on and off, the relays help to control the speed and direction of the vehicle.

Safety protection

Prevent overcurrent, short circuits, and other electrical faults that can be dangerous to the vehicle or its occupants.

Energy Efficiency

High-voltage DC relays can help to improve the energy efficiency of the vehicle by reducing energy losses in the electrical system.

High-voltage DC fuses are also one of the important protective components for battery systems. They can quickly cut off the circuit in the event of a battery system failure to protect the safety of the battery system and other electrical equipment. In addition, high-voltage DC fuses can also cut off the battery system circuit in the event of a vehicle accident, avoiding further discharge of the battery system and reducing the risk of safety accidents.

Protection Against Overcurrent

Protect the electrical system from overcurrent conditions that could potentially damage electrical components, by interrupting the flow of electricity when current exceeds a certain threshold.

Specific Component Protection

Protect specific components, such as the battery pack or electric motor, from overcurrent conditions that are unique to their operating requirements.

Safety Protection

High-voltage DC fuses prevent electrical hazards and ensure the safety of both the vehicle and its occupants.

Energy Efficiency

Limit current flow and prevent energy loss as heat, which can improve the vehicle's energy efficiency and extend its range.
