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.. . 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, making the resistance of.
