Battery Management System Circuit Design
When a violent short circuit occurs, the battery cells need to be protected fast. In Figure 5, you can see what's known as a self control protector (SCP) fuse, which is mean to be blown by the overvoltage control IC in case of overvoltages, driving pin 2 to ground. The Mcu can communicate the blown fuse's condition,. Here is implemented a low side current measurement, allowing direct connection to the MCU. Keeping a time reference and integrating the current. Temperature sensors, usually thermistors, are used both for temperature monitor and for safety intervention. In Figure 7, you can see a thermistor that controls an input of the overvoltage control IC. This artificially blows the SCP. Battery cells have given tolerances in their capacity and impedance. So, over cycles, a charge difference can accumulate among cells in series. If a weaker set of cells has less capacity, it will charge faster compared to others in. To act as switches, MOSFETs need their drain-source voltage to be Vds≤Vgs−VthVds≤Vgs−Vth. The electric current in the linear region is Id=k⋅(Vgs−Vth)⋅VdsId=k⋅(Vgs−Vth)⋅Vds,.
