Is the braking system of new energy vehicles the same as that of traditional vehicles?

Hello! The traditional braking system of fuel vehicle is mainly composed of brake pedal, brake master cylinder, vacuum booster, ABS pump, brake cylinder and brake pad. The electric vehicle is basically composed of the above components, but it has a vacuum pump and a vacuum gas storage tank more than the traditional fuel vehicle.

The vacuum booster of the traditional fuel vehicle needs the engine intake manifold to provide a vacuum environment, while the new energy electric vehicle has no engine and cannot provide a vacuum environment. Therefore, it is necessary to install a vacuum pump to vacuum, but the vacuum pump can't be directly connected to the booster, because when you step on the brake, the vacuum pump can't create the required vacuum immediately. Therefore, it is necessary to add a vacuum storage tank between the vacuum pump and the vacuum booster to store the vacuum and provide the required vacuum immediately when the booster is needed. Just like a river needs to build a reservoir, releasing water in dry season and storing water in rainy season.

Because the vacuum stored in the vacuum pump is limited, it is very dangerous to drive a new energy electric vehicle if you don't step on the brakes continuously and quickly, which will cause a serious shortage of vacuum, leading to the situation that the brakes don't help and the brakes are hard.
