What are the reasons for the insufficient braking of new energy vehicles?
2 Answers
The reasons for the insufficient braking of new energy vehicles are: Lack of necessary maintenance: Insufficient maintenance of the braking system, excessive impurities in the brake master cylinder, or failure of the vacuum booster pump; Improper operation: Mechanical failure caused by improper operation, such as prolonged downhill driving that causes the brake pads to generate heat through friction, carbonization of the brake drum, and complete failure of the braking function; Overloading: Severe overloading increases the vehicle's inertia due to gravitational acceleration, directly leading to brake failure. Methods to prevent brake failure include: Regularly inspecting the brake pedal, brake discs and pads, brake vacuum booster pump, and brake master cylinder. When inspecting the brake pads, also check the wear of the brake discs or drums, and regularly inspect and replace the brake fluid.
I often encounter situations where new energy vehicles fail to brake properly, mainly due to issues with the regenerative braking system. This system uses the motor to recover energy and assist in braking, but once it malfunctions or the battery level is low, the regenerative braking force weakens, and the hydraulic braking system takes time to compensate, leading to delayed or ineffective braking. Additionally, the hydraulic part is also problematic: insufficient brake fluid or leaks can cause low pressure; severely worn brake pads make the pedal feel soft; aging circuits or blown fuses directly interrupt signals. Environmental factors like wet and slippery roads or poor tire grip also contribute to the problem. I recommend not neglecting regular maintenance, checking the brake fluid and system software updates every six months, as these measures can prevent major disasters.
