Embodiment Construction

[0040] exist Figure 4 shows a battery system 100 according to a first embodiment of the invention, said battery system 100 comprising a battery 101 configured to supply a high voltage grid of a vehicle and at least one traction line 120 for supplying power to the battery 101, The contactor 10 present in 121 supplies an accumulator (not shown) of electrical energy. The battery 101 includes a plurality of battery modules 102 connected in series for generating a battery voltage suitable for a high-voltage grid. A contactor 10 is arranged in each of said traction lines 120 , 121 . The battery 101 can be connected to the positive high voltage terminal 130 of the battery 101 through one of the two contactors 10 , and connected to the negative high voltage terminal 131 of the battery 101 through the other of the two contactors.

[0041] Two parallel-connected consumers 140 , 141 are connected between the high-voltage terminals 130 , 131 of the battery 101 . Here, the positive hig...

Abstract

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 energy accumulator can continue to generate the control current flowing through the control coil for a first time by outputting the charged quantity of energy.

Description

technical field [0001] The invention relates to a battery system having a battery designed to supply a high-voltage network, which can be connected to at least one of its high-voltage network connections via a contactor. The invention also relates to a method for switching a contactor for a battery designed to supply a high-voltage network, via which the battery can be connected to one of the high-voltage network terminals of the battery. Furthermore, the invention relates to a vehicle having the battery system just mentioned. Background technique [0002] In vehicles (PKW), battery systems are used which have batteries which can supply a high voltage (high voltage) to the high-voltage network in each case. Therefore, the battery cells or battery modules of this battery are mostly connected in series. Then, such a battery must provide only a small current even at high power. In this case, the battery is connected via a traction line to the high-voltage terminal of the bat...
