It can transfer the civilian AC to DC and storage the electricity in the batteries by controlling the voltage and current.

It can be divided into two types according to the way the charger works:

Two-stage charging mode: Constant voltage charging is the first step. And the current will gradually reduce with the rise of the voltage. It will be switched to the trickle charge when the energy going up to certain extent; the voltage reaching the setting point.

Three-stage charging mode: The beginning of the charging is the constant current charging, and the constant current charging can supplement the batteries quickly, then switch to the constant voltage charging when the voltage raised. At this time, the energy will be replenished slowly, the voltage continues moving up until to the end point, then the trickle charge will instead the constant voltage charging in order to maintenance the batteries and supply the discharge current.

The main indicator of high-voltage fault is that the light does not shine or the light is flashing, and the output voltage is low and unstable; the reason of most low-voltage faults is that the positive and negative of both the charger and battery are reversed. The red light is bright and the green light does not shine. The output is low or close to 0V. When both high-voltage and low-voltage fail, we should check all the diodes, transistors, opto-coupler 4N35, FET, electrolytic capacitors, and integrated circuits before they are connected to power.

Some types of chargers also have a function of anti-reverse, and anti-short-circuit. The principle is different from that described above, its low-voltage circuit voltage is provided by rechargeable batteries, and then there is a diode (anti-reverse). After power supply is started normally, the low-voltage power will be provided by the charger.

The battery charge usually has two basic methods: charging contacts and inductively coupled charging.

Charging Contacts

Charging contacts adapt the tradtional contactor,and the users recharge the cars by contacting the charge source contactor to the cars. Danger is one of the disadvantages of this method since the conductor is outside. In addition, several times “plug in”and“non plug in” will lead to wear, and the energy can’t be transferred effectively.

People in China regard the electric bikes as transport tools but foreigners use these bikes mainly for leisure and fitness.

Phenomenon:

The failure mode of battery abroad is almost a single failure of the sulfide, accounting for more than 95%.But in China，it takes 66% for water loss in the failure mode，while water loss with sulfide existing in one battery holds more than 97%. Failure mode only for sulfide is just under 10%.

In order to realize standardization of design, it is necessary for a coupler in a car charger to charge use the same socket of electric vehicles. Restrictions on high-frequency transformer charger turn the wide range of factors, including power, electrical and mechanical design.

Among them, there are SAE J-1772 and SAE J-1773, which can be applied to contact charging method and inductively coupled charging method. It is necessary for electric vehicle charging system manufacturers to meet these standards in design and production of electric vehicle battery charger.

1. AC output socket of car charger converter has potentially danger which is just like General appliance socket that can be fatal, so it should take the same as household appliances socket.
2. Do not insert anything intot converter or ventilation hole.
3.Converter can not be watered.
4.Usually,electriferous AC wires can never connect directly with the converter .
5. Violation of the above operation may arise personal injury or converter damage.

Warning: Surface heat
Under the condition of overtime or high power use, surface temperature of car charger converter shell will up to 600C. When it is used, make sure the scope of the surrounding 5CM of converter is ventilation and do not put the objection that easily effect by high temperature nearby.

Warning:
1. Do not insert the product used DC power supply in converter.
2. Do not put converter under the place where the temperature higher than 50C.
