Advantages:
1. Use with 10-bit A / D converter PWM (12bits) of the eight microcontroller, A / D conversion precision to 1 / 1024, can satisfy the needs of testing the battery negative voltage.
2. Using software direct control AC / DC or DC / DC converter, for different constant current, constant voltage curve, so the whole line simple, low cost, high reliability, high efficiency power transfer Huan, less heat.
3. At the same time the use of: a) the maximum voltage; b) the maximum temperature rise; c) a negative voltage; d) to determine the maximum charge time for full charge of four methods to ensure that the battery charge, however, do not charge less, the software also can determine the battery voltage over lower case, with a small current charge, to restore damaged cells.
4. Software with test mode, can A / D conversion result is displayed by LCD module, and be corrected to ensure the production of products one hundred percent qualified.
5. At different stages of charge, can have different modes of instruction, can also personalize the design.
