Combined windings provides high torque, efficiency, power density, low cost and rejection of expensive materials.
The principles of winding schemes designing are patented in Russian Federation. Most part of the designs now in
the stage of patent pending. We planning to obtain from 50 to 100 patents.
We have an Russian Federation patent for electric vehicle with induction motor with combined windings.
Technology tested 18 years on thousands of motors common industrial execution with different powers, rotating
speeds and supply frequency.
Effectiveness of technology is guaranteed by testing protocols of Russian and European labs of manufacturing
enterprises and science institutes.
Drives with combined windings more than 2 years successfully passes pilot operation as part of different electric
vehicles.

BMS controls charging and discharging processes. At last charging stage device made balancing for cells. BMS made ​modular. It
consists of one main module A11031 and several additional modules A11032. Additional modules can be up to 63 pieces.
Each module serves 3 or 4 cells. For example for serves 11 cells we need one A11031 and two A11032 in 4+4+3 configuration.
All modules communicate via digital serial data bus.
Balancing current is 700mA.
Boundary voltages are set programmatically from 2V to 4.2V.
Charging controls for two ways:
Via embedded mosfets. Max current is 30A.
Via external relay that connected to Relay2 output.
