What are the reasons for the insufficient braking of new energy vehicles?

[RuthLynn]

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.

As a new energy vehicle owner, I once experienced an unresponsive brake pedal during emergency braking on the highway in my electric car. Later, I discovered it was due to improperly adjusted regenerative braking: when the battery level dropped below 20%, the system automatically limited the recovery force, leaving only traditional brakes to handle the situation. Compounding the issue, I was overloaded that day with a fully packed trunk, which increased the braking distance. The wet road surface made it worse, as tire slippage reduced effectiveness by half. Now I've learned my lesson: maintain the battery above half capacity, avoid aggressive acceleration while driving, and reduce speed in rainy conditions. Regular checks on tire tread patterns and brake disc wear have made these small adjustments crucial for safer driving.

As a tech enthusiast, I've looked into braking issues in new energy vehicles: the electronic control unit (ECU) malfunction is often the root cause. Faulty sensors like wheel speed sensors can misjudge the vehicle speed, leading to inaccurate regenerative braking force adjustment; software bugs causing execution lag result in delayed brake response. Other risks include wiring harness short circuits or poor contact, leading to unstable current; the system automatically reduces power when the battery overheats. Doing some DIY checks, such as scanning the OBD port for error codes or manually testing regenerative braking sensitivity, can help identify problems earlier.
