具有可通过接触器与其高压端子中的至少一个相连的电池的电池系统和用于切换这种接触器的方法
Abstract:
本发明涉及一种具有被构造用于给高压电网供电的电池的电池系统，所述电池可通过接触器（10）与该电池的高压电网端子中的至少一个相连，所述接触器（10）包括控制线圈（20）并且在控制电流流经控制线圈的状态下闭合，而在没有电流流经控制线圈的另一状态下断开。在此，为了产生控制电流，控制线圈可通过供电电路（80）被连接到供电单元（50）上，借助于所述供电单元（50）可提供预先确定的电压，所述预先确定的电压小于由电池所产生的电压。此外，该接触器或者该供电电路还包括蓄能器（90），所述蓄能器（90）可借助于在控制线圈上连接的并且提供所述预先确定的电压的供电单元以预先确定的电能量来充电，而且所述蓄能器（90）可在去掉预先确定的电压的情况下在第一时间内通过放出所充电的能量而继续产生流经控制线圈的控制电流。
Abstract(English):

The present invention relates to a battery system having a battery which is designed to supply a high-voltage power system and can be connected by at least one of its high-voltage power system terminals via a contactor (10), which battery system comprises a control coil (20), and closes in one state in which a control current flows through the control coil, and opens in a further state in which no current flows through the control coil. In this context, in order to generate the control current, the control coil can be connected via a supply circuit (80) to a supply unit (50) by means of which a predetermined voltage can be made available which is lower than the voltage generated by the battery. In addition, the contactor or the supply circuit comprises an energy accumulator (90) which can be charged with a predetermined quantity of electrical energy by means of the supply unit which is connected to the control coil and makes available the predetermined voltage, and in the event of the predetermined voltage being lost, said contactor can continue to generate the control current flowing through the control coil for a first time by outputting the charged quantity of energy.
