What are the reasons for the inability to brake in new energy vehicles?
2 Answers
New energy vehicles may fail to brake due to the following reasons: 1. Lack of necessary maintenance on the braking system, excessive impurities in the brake master cylinder, or failure of the vacuum booster pump; 2. Improper operation leading to mechanical failure, such as prolonged downhill driving causing brake pad friction heat, brake drum carbonization, and complete loss of braking function; 3. Severe overloading, which increases the vehicle's momentum under gravitational acceleration, directly resulting in 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 checking the brake pads, it is also necessary to examine the wear of the brake discs or drums, and to regularly inspect and replace the brake fluid.
I've been driving electric vehicles for a while and noticed there are quite a few reasons why the brakes might feel inadequate, especially issues with the regenerative braking system. This system relies on the motor to recover energy, but if the battery is fully charged or malfunctions, it can't absorb the braking energy, leading to weaker physical braking. Software bugs are another concern—like incorrect settings after a system update, causing the computer to misjudge whether to use electronic braking or traditional brake pads. Additionally, faulty small components in the control system, such as sensors, can slow down the entire braking response. In winter when roads are slippery, regenerative braking might be suppressed, increasing the risk of accidents. I recommend keeping your software updated, checking battery health regularly, and visiting a professional shop for diagnostics when needed. After all, brake failure is extremely dangerous—safety comes first.
