1. Lithium batteries, nickel hydrogen battery choice function: then is 2-4 lithium polymer battery parallel (differential pressure) charges, charges, also may for the nickel hydrogen battery series charge. (predetermined value is lithium electricity)

2. Duration of charging control function: May establish the duration of charging voluntarily, after achieved the hypothesis the duration of charging, stops the charge (predetermined value is automatically 3 hours)

3. Charge protections (closure) voltage choice, but establishes three kind of charge blackout voltage artificially, 4.15V, 4.25V,4.35V (the predetermined value is 4.15V).

4. charging current hypothesis: May choose 0.5A, 0.7A, 0.9A, 1.1mA, four kind of charging currents (The predetermined value is 0.5mA)

5. Rechargeable battery quantity choice: The lithium polymer battery may establish 1-4 charge. The nickel hydrogen battery may choose 1-9 battery. When dose not establish the battery quantity, the lithium battery charges automatic detection battery quantity.

6.battery tie hands behind the back the protection function: when turns on battery polarity mistake, may send out reports to the police the sound, simultaneously demonstrated ties hands behind the back the prompt, simultaneously demonstrated which battery meets instead, and automatic stop charge.

7. Automatic repair functions: If group of lithium batteries in charge time, some or several battery electric discharge, has created the voltage excessively to be low, this time like with other battery equally big electric current charge, extremely easy to have created the discharged battery irremediable defect. when this battery charger turning on battery, automatic detection each battery voltage, if examines time the discharged battery (the single-node is lower than 2.4V), the battery charger transfers the undercurrent charge automatically, when the battery voltage achieves 2.After 4V, then transfers the normal electric current charge, avoids the big electric current charge creating the battery the permanent damage.

8.Bad battery examinations reports to the police the function: When group of lithium batteries charge, if or several battery damage, but the automatic buzzer reports to the police, and on LCD demonstrated the damage the battery position, simultaneously finished the charge.

9. charge conclusion prompt function: after charges achieved the hypothesis the protection voltage or achieved the duration of charging, the charge automatic stop, and sends out the sound prompt and the LCD demonstration.

10. LCD demonstrates the function

* Establishes and demonstrated chooses LI or the NI-MH battery carries on the charge.

* Establishes and demonstrates the duration of charging (countdown).

* Establishes and demonstrates the lithium battery safe charging voltage (4.15V, 4.25V, 4.35V): After the lithium battery demonstrates each battery dynamic charging voltage and the entire group battery dynamic voltage and the battery fill quiescent voltage; After nickel hydrogen battery demonstration series dynamic voltage and fill static state voltage.

* Establishes and demonstrates the charging current (500mA, 700mA, 900mA, 1100mA): The lithium battery demonstrates each battery charging current; Nickel hydrogen battery demonstration series charging current.

*Establishment and demonstration rechargeable battery quantity (lithium battery 1-4, nickel hydrogen battery 1-9)

*Demonstrated the battery ties hands behind the back and ties hands behind the back the battery position.

*The demonstration repair battery and the repair battery position, quantity and demonstrates each lithium battery the repair electric current.

*The demonstration has damaged the battery and damage battery position quantity.

*Demonstrated the battery has filled.

11. Buzzer prompt function: In on electricity starting, the manual establishment, the battery ties hands behind the back, the battery damage, links and so on charge conclusion all have the sound prompt.

We provide the picture to look at this IC each position the difference. Thanks this battery charger examination way is A/D the simulation / numeral examination. The accuracy is extremely high. But the common battery charger use comparator examination pattern does not have the procedure. The accuracy is low.
