The significance of EV high-voltage cables as warning signs

Relevant standards stipulate that the high-voltage cables connected to the internal components of electric vehicles usually reach thousands of volts of high-voltage electricity. Once an accident occurs, the harm to the human body is very great. People play the role of reminder and alert, let's find out together.

1. The international requirements for cables connected to high-voltage electricity are orange, which plays a warning role. Compared with low-voltage control lines, high-voltage cables are much thicker and easy to identify.

2. There will be warning signs of high voltage on the shell of the controller or actuator with high voltage.

There are three main types of high voltage for new energy vehicles: continuous existence, existence during operation, and existence during charging. However, in general pure electric vehicles, the high-voltage cable is orange. Compared with the low-voltage control circuit, the high-voltage cable is much thicker and easier to identify. In addition, the high-voltage controller or the actuator shell will be marked with a high-voltage warning sign.

If there is an orange wire harness on a family car, the components connected to it are high-voltage components, generally including power battery packs, drive motors, motor controllers, DC/DC converters, high-voltage distribution boxes, electric air conditioners, PTC heaters, and on-board charging systems. , Off-board charging system, etc.
