What Causes Electric Vehicles to Have Poor Braking Performance?
2 Answers
Electric vehicles experiencing unresponsive brakes is typically an issue with the booster. Below is an introduction to the booster: 1. Overview: The booster is a vehicle control device that utilizes compressed air, high-pressure oil, etc., to achieve ease of operation. 2. Conditions: Due to the limited physical strength required for operating large vehicles, many "boosting" devices are employed, formally known as "servo mechanisms," such as hydraulic power steering, vacuum-assisted braking, and air-pressure-boosted braking. 3. Considerations: Different vehicles may use servo mechanisms in varying locations and forms, but the general principle remains the same: a small signal action leverages compressed air, high-pressure oil, etc., to control related vehicle devices, aiming for ease of operation.
I've been driving an electric car for over three years, and the issue of ineffective braking is really frustrating. There are usually several common reasons. First is a problem with the regenerative braking system. Electric vehicles mainly rely on this system to recover energy during deceleration, but if there's a software glitch or sensor failure, it stops working, forcing the mechanical brakes to bear the full load, which slows down the response. Another major issue is hydraulic system leaks, such as insufficient brake fluid or cracks in the pipelines, leading to inadequate pressure when braking. Additionally, excessive wear on brake discs and pads occurs because regenerative braking shares the friction task, but during emergencies, the load increases significantly, accelerating wear. Slippery weather conditions can also affect braking, as tire slippage reduces braking efficiency. I recommend checking the braking system every three months, especially the battery status and hydraulic fluid levels. Safety comes first—don't wait for an accident to regret it.
