Balance the internal and external pressure difference of the obc car charger




Balance the internal and external pressure difference of the obc car charger

China's vehicle-mounted vehicle chargers have obvious comparative advantages under global resource conditions and have great development potential. From the perspective of the new energy vehicle industry chain, the beneficiary side will mainly focus on the core components.

When the OBC on-board charger is working, the temperature of the sealed cavity rises and needs to withstand strong pressure, which leads to seal failure, and liquids such as dust, water and oil are sucked in, so the problem and the key factors affecting the normal working and the longevity of the motor are this.

Professional protection solutions:

1. Balance the pressure difference between inside and outside to avoid accumulation of foreign objects, water, oil, dust, etc.;

2, waterproof and breathable, to avoid water vapor entering the cavity, changing the structure of the motor structure designers in the past through the structural way waterproof and breathable can not be fundamentally solved;

3, easy to install, just open a hole in the shell or attached to solve it;

4. Extend the service life of the motor.
