Smart BMS with bluetooth

DIY Bluetooth module

Replacement Lishui Bluetooth module



Hello everybody,

I have taken the trouble to analyze the Bluetooth module of Lishui more precisely and found that it is easy to reconstruct with standard components.

images/87-1.png

An HM-10 module is used for communication. The voltage supply for this is made by a DC / DC converter, for safety with a downstream 3.3V voltage regulator. The 36V for activating the controller are switched via a Smart High-Side Switch. I have taken a BTS432 E2, which is hopelessly oversized, but was grad to hand.

The controller is switched on and off via the PIO2 pin, the battery voltage is read in via a voltage divider to PIO4. The rest is over UART. The module is simply plugged into the controller instead of the display.

The HM-10 must be properly configured with some AT commands, then the replica runs smoothly with the Fore-Rider app from Lishui :-)
Of the HM-10 modules are probably a lot of fakes in circulation, mine has worked fortunately.
