Active discharge device and process

摘要

An active discharge device (200) of the electric energy storage device (C1) is provided,The utility model comprises: - a branch (204), the first end and the second end (206208) of which are respectively connected to the positive terminal and the negative terminal of the electric energy storage device (C1),Between the ends (206208),A thermistor (210) whose resistance increases with the temperature of the thermistor (210), and a switch (212) designed to receive a control signal (VGS) to switch from an open state to a closed state,The thermistor (210) and the switch (212) are connected to each other so that when the switch (212) is in the closed state,The discharge current (ID) enters through the first end (206),Passing through the thermistor (210) and the switch (212) successively and exiting from the second end (208);And a control device (214) of the - switch (212).A control device (214) is connected to a switch (212) to provide a control signal (VGS) independent of the thermistor (210).Abstract figure: Figure 2
