What does temporary weakening of Tesla's regenerative braking mean?
2 Answers
Tesla's temporary weakening of regenerative braking is a vehicle system. Here is an introduction to the regenerative braking system: Introduction: The regenerative braking system refers to a system applied to automobiles or rail transit that can convert the heat energy generated during braking into mechanical energy and store it in a capacitor. The energy can be quickly released when needed. Advantages: These intelligent technologies improve engine efficiency, moderately reduce fuel consumption, and further enhance driving pleasure. A good example here is the regenerative braking system. The energy management system ensures that the engine's output power is mainly converted into driving force, and only when braking is applied or the engine is in an overspeed state will it be converted into electrical energy for use by the vehicle's systems. To achieve this effect, the generator automatically disengages from the engine when the engine is outputting power, such as during acceleration or when towing the vehicle.
I just encountered this Tesla alert the other day. It happened on a downhill section when the regenerative braking suddenly weakened, and the brake pedal feel changed. After checking the manual, I realized it's mainly due to battery conditions: during cold winter temperatures or when the battery is fully charged, the system can't absorb much regenerative energy. Just like how forcing a fully charged phone to charge more can damage the battery, the car activates a protection mechanism. In this case, dashed lines appear on the energy bar on the right side of the dashboard. I chose to set the charge limit to 90%, and after driving a few kilometers to consume some charge, it returned to normal. Occasionally, this also happens after system updates, but there's no need to worry—the mechanical brakes remain reliable.
