The most comprehensive knowledge of car battery chargers
How to use the car battery charger, first connect the positive pole of the charger to the positive pole of the battery, and then press the charging button to charge. When charging, you don't have to wait for the battery to be fully charged before unplugging. You only need to have enough power to start the automobile engine. The automobile will drive the engine through the leather belt, and the generated electricity will be rectified and stabilized to directly charge the automobile battery.
Automobile battery, also called storage battery, is a kind of battery, its working principle is to convert chemical energy into electric energy. Usually, the battery that people call refers to a lead-acid battery. That is a storage battery that is mainly made of lead and its oxides and whose electrolyte is a sulfuric acid solution. When the car has run out of electricity and can't start the engine, it is natural to charge the battery, and using the battery charger can be said to be the most convenient method. Pay attention when charging. Never overcharge the battery with the battery. Although the current generated by the charger is not very large because the electrolyte is in a boiling state for a long time, not only the fine particles on the surface of the active material are easy to fall off, but also the grid frame will be oxidized in serious cases, resulting in loose stripping of the active material from the grid frame. Therefore, pay attention when charging. After some batteries are used up, the internal resistance becomes very large, which will be full once charged and finished once discharged. It is normal for this kind of battery to use a three-way meter to detect its no-load voltage. Therefore, not only the no-load voltage but also its discharge current can be measured, which can be measured by a discharge instrument. When discharging, it is normal that the voltage is not lower than 10V. If it is lower than 10V, it proves that the battery may be broken and must be replaced. The lower the voltage when loading, the greater the internal resistance of the battery, the worse the discharge characteristics.
In the process of charging the car, first, connect the positive pole of the charger to the positive pole of the battery, and then press the charging button to charge. But don't overcharge the battery frequently. Although the current generated by the charger is not very large because the electrolyte is in a boiling state for a long time, not only the fine particles on the surface of the active material are easy to fall off, but also the grid frame will be oxidized seriously, resulting in loose peeling of the active material from the grid frame.
How to use the car battery charger:
1. Turn off the engine first, then remove the battery from the car, find a ventilated and cool place, and open the ventilation cover on the battery;
2. Clamp the charger's red pliers to the positive electrode of the battery with the plus sign and the black pliers to the negative electrode of the battery with the MINUS sign;
3. Because it is a used battery, it should be charged slowly when charging. It is necessary to adjust the gear to 2 and choose a 12-volt power supply. The current can be seen from the meter;
4. Plug in the charger and turn on the switch to charge the battery. Most charging time should not exceed 12 hours.
At present, many electric vehicles in the market will be equipped with several charging interfaces, and charging with charging piles will have a higher safety factor than charging with ordinary 220V sockets. Because of the high energy release rate of electric vehicles, the fire spread speed of electric vehicles is faster than that of fuel vehicles. Once a fire occurs, it is very dangerous. Some car owners like to put the charging gun equipped by the manufacturer in the trunk of the car, which is convenient for charging at any time, but this practice has hidden risks. The car is parked outdoors, the temperature inside the car is very high, and the charging gun is likely to accelerate aging and break down. Members of the public should keep the charging device in a cool and ventilated place, and take it out when charging is needed.
