Switching arrangement in motor vehicles for ensuring the optimum charge state of the battery of the vehicle electrical system

摘要

In a switching arrangement in motor vehicles for ensuring the optimum charge state of the battery (B) of the vehicle electrical system during driving, comprising a battery (B) of the vehicle electrical system, low-voltage loads (V1...Vn) and high-power loads (VL) as well as a first generator (G1) and second generator (G2), in which the first generator (G1) is connected at least to the low-voltage loads (V1...Vn), the battery (B) of the vehicle electrical system can be switched exclusively to the second generator (G2) when the supply voltage (UB) of the battery (B) of the vehicle electrical system is below a predetermined value. <IMAGE>
