This product is the HT45F85x0 MCU development board for Holtek BMS Workshop. It is used with the HT45F85x0 MCU adaptor board to form a complete Li-ion battery management control board. With the use of Holtek BMS Workshop, a Li-ion battery management system can be easily built.

The product functions include temperature and short circuit protection circuits. It also includes accumulated battery voltage monitor and high-accurate voltage regulator. It is suitable for 3 to 8 cell Li-ion battery products, such as power tools, cordless hair dryers, cordless vacuum cleaners and so on.

The HT45F85x0 MCU development board can be used with the 3 to 8 cell Li-ion battery emulation board and the HT45F85x0 MCU adaptor board. The control program generated by the Workshop can be programmed to the MCU with e-Link or e-WriterPro.

Holtek provides BMS Workshop, with which the Li-ion battery protection functions can be set and tested by users. Users can change the following settings :

1. Protection functions for battery charging, discharging, short circuit and temperature
2. Pins parameters
3. Lights display mode：low voltage, battery failure, charging finished, etc.
4. Voltage calibration
5. Software parameters
6. Coulometer

When selecting discharge circuit parts, please note the temperature rise of the parts during long-term use.
