What is the solution for BMW X3's low-speed jerking?
1 Answers
BMW X3's low-speed jerking is mostly caused by the intervention of BMW's kinetic energy recovery system, which can be resolved by unchecking the coasting option in the driving mode. Below is an extended introduction to this issue: 1. Introduction to the kinetic energy recovery system: The kinetic energy recovery system activates the generator when the driver releases the accelerator pedal or presses the brake pedal, converting the excess energy generated by the car's movement into electrical energy, thereby reducing fuel consumption. 2. Introduction to battery charging: As long as the engine is running, the generator will operate accordingly, continuously charging the battery. However, this operation is sometimes redundant because the battery may not require that much power, and electronic devices may not consume that much electricity, so there is no need to always have the generator producing electricity to consume the engine's power. Since BMW uses AGM maintenance-free batteries, the battery has a longer service life and more sufficient power storage. In most cases, it is sufficient to meet the power demand. Therefore, the system will only connect the generator to charge the battery when the battery level drops to 50%.
