The present disclosure relates to a discharge device and an inverter, the discharge device comprising: a first switching circuit which is turned on when a first discharge control signal is received, and which is turned off when the first discharge control signal is not received, and which is turned off when the first discharge control signal is not received; wherein the first discharge control signal is a discharge control signal generated when an emergency stop event occurs; and a first discharge circuit including a discharge conductor having an equivalent resistance less than a resistance threshold or falling within a resistance threshold range, and a tolerable temperature higher than a tolerable temperature threshold or falling within a tolerable temperature threshold range, and the electric energy in the direct current link capacitor of the new energy automobile is released through the discharge conductor. Therefore, the release of the electric energy in the direct current link capacitor of the new energy automobile can be completed within the millisecond-level discharge time under the condition that an emergency stop event such as a collision event occurs.
本公开涉及一种放电装置及逆变器,该放电装置包括:第一开关电路,其中,在接收到第一放电控制信号的情况下,使所述第一开关电路接通,在未接收到所述第一放电控制信号的情况下,使所述第一开关电路断开,其中所述第一放电控制信号是在发生急停事件时生成的放电控制信号;以及第一放电电路,其包括等效电阻小于电阻阈值或者落入电阻阈值范围、并且耐受温度高于耐受温度阈值或者落入耐受温度阈值范围的放电导体,其中,在所述第一开关电路接通的情况下,经由所述放电导体来释放所述新能源汽车的直流链路电容中的电能。由此,能够在发生急停事件比如碰撞事件的情况下在毫秒级的放电时间内完成新能源汽车的直流链路电容中的电能的释放。
