How long can a car be fully charged at idle speed?

If the battery is normal, the car can be fully charged at idle speed 1 to 2 hours. The time required for idling charging may vary from car to car, depending on the actual situation. If the battery is dead, it is difficult to fully charge the battery at idle speed. If the battery is dead, it is recommended to use a special charger to charge it.

If the battery of the car is dead, it will take about 16 to 20 hours to charge with the generator, which takes a long time. Take 12 volt 60 A H battery as an example. The charging mode is constant voltage and current limiting mode, constant voltage 14.8V, current limiting 15A charging16h. Therefore, if the battery of the vehicle is dead, please use an external power supply to charge it. It takes a long time to charge him with the generator of the vehicle, and it also consumes the fuel of the vehicle. If the battery of the vehicle is dead, it is recommended to use a charger to charge the battery of the vehicle.

When the vehicle is charging at idle speed, the owner should turn off all electrical equipment on the vehicle and turn off the lights at the same time, so as to avoid other electrical appliances consuming electricity and easily damaging the vehicle battery. Because when the engine is idling, the current usually used is small, if the vehicle does not use other electronic equipment at this time, the small current will accelerate the charging of the battery.

What is the reason for the unstable idle speed of the car?

After the inspection, the idle speed of the car is unstable. What is the reason? The idling speed of automobile engine is unstable. It refers to the unbalanced force in the cylinder of the automobile engine, which causes the piston to collide when doing work, causing the engine to shake and making the idle speed deviate from the normal standard range. Engine idling instability is a common fault in engine maintenance. Cause of unstable idle speed of engine: 1. Air leakage in the intake pipe If the intake pipe leaks, the gas inside the engine will lose balance, making the pressure too large or too small, thus causing the problem of unstable idle speed of the car.

The reasons for unstable idle speed are: 1, too much carbon deposition in the throttle; 2. The leakage of intake manifold or various valves directly affects the quality of fuel mixture and combustion effect; 3, valve timing fault, valve timing dislocation, timing belt installation error, excessive carbon deposition in the intake and exhaust valves, valve spring fracture, etc. The idle speed will be unstable due to the different air intake of each cylinder. Unstable idle speed, high and low, is an unbalanced force in the cylinder of an automobile engine, which causes the piston to collide when doing work, causing the engine to shake and making the idle speed deviate from the normal standard range. Engine idling instability is a common fault in engine maintenance.
