Directly from the low-voltage lighting circuit, charging power is small, by 220V\/16A specifications of the standard grid power supply. The typical charging time is 8 ~ 10h. This charging method has no special requirements for the power grid, and can be used as long as the power supply quality can meet the lighting requirements.

Small charging stations are one of the most important ways to charge electric vehicles, and charging piles are set up on the street, supermarkets, office buildings, parking lots and other places. The electric vehicle driver only needs to park the car at the designated position of the charging station, connect the wire to start charging, the charging method is generally swiped card, the charging power is generally 5 ~ 10kW, and the typical charging time is: recharge 1 ~ 2h, full of 5 ~ 8h.

3. Fast charging
< br >
Dc electric vehicle charging station, commonly known as \"fast charge\
< br >
4. Wireless charging of electric vehicles
< br >
In recent years, foreign research results, the principle is like the mobile phone used in the car - converts electrical energy into a special laser or microwave beam that meets the requirements of current technical standards, and can be received by a special antenna installed on the roof of the car. With wireless charging technology, electric or dual-energy vehicles driving on the road can be quickly replenished by transmitters mounted on telephone poles or other tall buildings. The electricity bill will be deducted from the prepaid card installed on the car.

Soled DC portable charger consists of intelligent and efficient module, main control unit, human-computer interaction interface, charging interface, metering and billing unit, communication interface and other parts of a small portable and multi-function DC charger; The friendly man-machine interface is convenient for users to operate and use, and the modular design is convenient for equipment expansion and maintenance; Support automatic charging mode;
< br >
Portable DC charger has strong seismic ability, complete protection function, suitable for harsh outdoor mobile environment and emergency needs; It is convenient for customers to quickly emergency and test the place of replenishment of electric energy, and effectively compensate for the problem of non-charging caused by the compatibility problem with various charging pile software.
There are three common charging methods:
< br >
1. Constant current charging: Maintaining a constant current to charge the battery during the charging process is the most common way to charge, and the general charger uses constant current charging.
< br >
2. Constant voltage charging: maintain a constant voltage to charge the battery during the charging process, and the current in the circuit gradually decreases as the battery voltage increases.
< br >
3. Constant current and constant voltage charging: First charge the battery with constant current, when the battery voltage rises to a certain value, the voltage remains unchanged, and the battery is charged with constant voltage, and the current in the circuit is reduced to a small amount until the charging is completed.
1, pulse charging, both simple and economical, this method of charging current is large, charging speed is fast, the disadvantage is that when the grid voltage fluctuations, charging current also fluctuates.
< br >
2, constant current charging, in order to prevent the temperature rise in the battery is too high and the loss of the electrolyte is too large, the charging current is relatively small, and the charging time is longer, on the other hand, the charging time is too long, overcharging will occur, in order to prevent damage to the battery due to overcharging, it is necessary to set up another overcharge detection or timing circuit.
< br >
3, constant voltage charging, both theory and practice have proved that when the charging voltage is lower than the upper limit of the charging voltage (for the 12V battery, this value is), constant voltage charging is safe, even if the charging time is very long, there is no danger, if necessary, the battery can also work in the floating state.
The common charging methods are as follows;
< br >
1, you can directly use the mobile phone charging port, connect the mobile phone charger to charge;
< br >
2, you can also take the phone battery, take it off, and charge it with a universal charger;
< br >
3, can also be charged with mobile power;
< br >
4, when you do not bring a charger, you can also use someone else's mobile phone to charge (provided that the battery size and connection electrode should be the same).
< br >
5, there is no universal charger, only ordinary lithium battery charger, the battery can not be connected to the charger, but also with a wire connection charging.
