How to charge the car when it is out of power

The method of charging the car without power: Method 1: First, there should be two wires, and a car that can run; secondly , the two cars can't be parked too far away, because the wire is only two meters long. Make sure that the car that can run is on fire, because the voltage output is the most stable when the car is running.

Use the emergency start-up power supply.Now there is an emergency power bank on the market, which can provide a powerful current for vehicles that lose power to start the engine, which is very convenient and saves the trouble of finding a 4S store for rescue or a car to charge the power.

To charge a dead car, you need to prepare a set of jumpers and a fully charged car. Then, it is necessary to connect the batteries of the two cars with a cross-connected cable, with the positive pole to the positive pole and the negative pole to the negative pole, so that the electrical energy in the charged battery can be transferred to the battery without electricity. Start the exhausted car 1.

A portable charger can be used to charge, and the positive and negative junctions of the charger correspond to the positive and negative terminals of the battery, and make sure that the connection is firmly connected and then turn it on to charge. Charging method: Take 12V60Ah as an example, the constant voltage current-limiting method is used for charging, constant voltage 18V current limitation 15A charging for 16 hours, and then charging with 3A constant current for 4 hours, a total of 20 hours.

Generally speaking, if it can't start, the reason why the engine "squeaks" as soon as it is turned on may be that the car battery is out of power. So what should we do? Today, I will take you to have a good understanding.

How to charge the car battery

The charging methods of the car battery are: cross-connection power-on method, charger charging, trolley. The cross-connection method means that the battery of another car is connected to the battery, positive pole, positive pole and negative pole of another car without power. In this way, cars without electricity can start the engine through power transmission.

Use the red clip of the charger to clamp the positive pole, the black clip to clamp the negative pole, and plug in the power cord to charge. At this time, the current and voltage gauges on the charger will rise.Then adjust the charging current button to control the charging size. In this way, the charging can be completed.

The used battery should be charged slowly when charging. Select the 12-volt power supply, select the low gear to slowly charge the battery, plug in the charger power supply, turn on the switch, and the battery can be charged. The charging time should not exceed 12 hours.

The correct way to charge car batteries

The correct ways to charge car batteries are: cross-connection power, charger charging, trolley. The cross-connection method means that the battery of another car is connected to the battery, positive pole, positive pole and negative pole of another car without power. In this way, cars without electricity can start the engine through power transmission.

The correct way to charge the car battery is to turn off the engine and remove the battery from the car. Adjust the liquid level of the battery to the specified height of 10-15 mm. Distilled water or battery-specific replenishment can be used. Connect the battery to be charged according to the rated voltage and current specified by the charging device.

Slow charging, there is also a charging method for car batteries, for slow chargingElectricity, the charging time is 10-15 hours. Those batteries must be charged slowly, otherwise the charging time is insufficient, which will directly affect the driving performance of the car.
