Due to a charging system failure, the battery light is on, the tailgate cannot be lifted after the engine is turned off, and the dashboard displays a low battery level. Below are the specific details: 1. Analysis of Fault Symptoms: Abnormal alternator. Issues with the battery monitoring system. Faulty gateway module. Loose battery terminals. Problems with the battery itself. Failure of the auxiliary small battery. 2. Fault Inspection: Checked the battery terminals and found no looseness, ruling out terminal connection issues. It might be a single battery, eliminating the auxiliary battery problem. Measured the alternator output with a multimeter at 14.3V, observed voltage changes when switching electrical devices, and measured the starting voltage at 11.23V, confirming that both the alternator and battery are functioning normally.

Can a Car Charge Its Battery While Idling in Place?

Car can charge its battery while idling in place, but the electricity charged in this situation is called "floating charge," which only exists for a short time. Here is the relevant introduction about car idling: 1. Introduction: Car idling is not a speed, but refers to a working condition. When the engine is running without load, it is called idling. When the engine is running, if the accelerator pedal is completely released, the engine is in an idling state. The speed of the engine during idling is called the idling speed. The idling speed can be adjusted by changing the throttle size. Generally speaking, the best idling speed is the lowest speed at which the engine does not shake. 2. Function: Idling is to overcome the engine's own operating resistance and maintain the minimum engine speed, so as to provide convenience for the driver to drive and temporarily park in various situations. For example, when waiting for a traffic light or in a traffic jam, although the time is short, temporarily turning off the engine can bring immediate energy-saving and emission-reduction effects.
