 PTDS-B High frequency microcomputer automatic charger

Product overview:

Our new automatic charger are used with microcomputer control imported from the United States, designed according with the optimal battery charging curve of accumulator battery, fully perfect protections and equipped with intelligent LED charging instructions. And especially it has environment temperature automatic compensation function. It avoides the problems, overcharging in Summer and insufficient charging in winter. It can effectively extend the battery life. The Charging process does not need the participation of customers. It is really a "fool operation" charger.

This product is widely used in electric passenger trolley tricycle, electric bus, electric pallet truck, electric garbage truck, electric sweeping vehicles and other electric vehicles

Ⅱ Product features:

★ Reverse protection:

When the output plug of the charger output plug and battery polarity are reversed, the charger will not work. Connecting to the right way will work normally.

★ Overcurrent protection:

When the charging current is more than the setting value, the charger will cut off the output. After the charger stops working for 3 seconds, it will automatically restart.

★ Overheating protection:

When the charger temperature reaches to 85 ℃, it will automatically adjust the output power in order to ensure the charger temperature no more than 85 ℃.

★ Temperature compensation:

According to the ambient temperature, the charger will automatically adjust the charging parameters to ensure not overcharge in Summer and insufficient charge in winter

★ Short circuit protection:

When the output is short circuit, the charger is automatically protected and turned off the output. After 3 seconds, the charger will automatically restart to work.

★ Automatic shutdown:

When the battery is fully charged or reached to the setting maximum charge time, the charger will be automatically turned down.

★ Overvoltage protection:

When the output voltage exceeds the setting value, the charger will turn off the output. After the fault is removed, it will automatically restart to work.

Ⅲ Charging process:

★ Pre-charge stage:

When the battery voltage is below the setting value, it will precharge with a small current. When the battery voltage is reached to the setting value, it will turn to costant current charging stage.

★ Constant current stage:

When the charging voltage is reached to the setting value in this stage, it will turn to constant voltage charge stage. The charging current is constant, the battery voltage is increased gradually.

★ Constant voltage stage:

When the voltage rises to the setting value in constant current stage, the charger will turn to constant voltage charging. In this stage, the charging voltage is constant, the current is decreased gradually.

★ Pulse charge:

It is an interval charging stage. Usually it is charing with constant current in a period of time. Then stop charging for some time. For example, charging for 10 seconds, stop for 5 seconds. The time will be set according to customer or battery requirements.

★ Automatic shut down:

When the charging time is more than the setting value or the current is smaller than the setting value in constant voltage charge stage, the charger will stop working.

Note: The charging process can be set according to the requirements of the battery manufacturers.
