The invention relates to a method for active discharge of an electrical energy store, a control device, a circuit arrangement and a motor vehicle. In particular to a method for actively discharging an electrical energy storage device by means of a circuit arrangement comprising at least one half-bridge consisting of two switching elements which are connected in parallel to the energy storage device and which each have a switchable section, the resistance of the energy storage device can be set by a control voltage of the switching element in a passing mode of the switching element. According to a discharge current specification describing a value of a discharge current of the energy store, a value of a control voltage and/or a ratio between an ON duration and an OFF duration of a switchable section of the switching element in the pass mode is set, a switchable section of the switching element is operated in a pass mode during the discharge; the switchable section of the switching element is operated in a blocking mode during the discharge during the turn-off duration.
本发明涉及一种电能存储器的主动放电的方法、控制装置、电路设备和机动车。尤其是涉及一种用于通过电路装置对电能存储装置进行主动放电的方法,电路装置包括至少一个由两个开关元件构成的半桥,半桥与能量存储器并联连接,开关元件分别具有可开关的部段,其电阻在开关元件的通行模式中能通过开关元件的控制电压来设置,为了使能量存储器放电,根据描述能量存储器的放电电流的数值的放电电流规范来设置在通行模式中的开关元件的可开关的部段的控制电压的数值和/或导通持续时间与关断持续时间之间的比,在导通持续时间内,开关元件的可开关的部段在放电期间以通行模式运行;在关断持续时间内,开关元件的可开关的部段在放电期间以阻断模式运行。
