摘要:
A battery sensor data transmission unit is described as including a connection state ascertainment unit for ascertaining a series connection state in which a battery cell is connected in series to one other battery cell with the aid of a power transmission line and/or for determining a bypassing state in which at least one pole of the battery cell is decoupled from at least one other battery cell. Furthermore, the battery sensor data transmission unit includes a data transmission unit designed for outputting a sensor signal, which represents a physical variable in or at the battery cell, in the series connection state to an evaluation device using the power transmission line and/or outputting the sensor signal in the bypassing state to the evaluation device using a battery housing wall as the transmission medium.

A circuit for a battery includes a number n of battery cells which are connected in series between a positive battery terminal and a negative battery terminal. The number n is a natural number greater than 1. Due to the mounting in series of the n battery cells, a number of connection points are obtained between the n battery cell. The circuit further includes a discharge element comprising a first terminal which is connected or can be connected to a first discharge line and a second terminal which is connected or can be connected to a second discharge line. The circuit also includes a number of switches which can be connected at a first terminal to a respective connection point or to one of the positive or negative battery terminals and are connected at a second terminal to the first or second discharge line.

摘要:
A method for maintaining a predetermined voltage in a battery-supported vehicle electrical system during the operation of an electrical starter includes steps of operating the electrical starter on the vehicle electrical system during a first time phase in series with a limiting resistor, in order to limit the current flowing through the starter, and operating the electrical starter on the vehicle electrical system during a second time phase with a reduced limiting resistance, in order to increase a power converted by the starter. A transition from the first time phase to the second time phase is controlled on the basis of electrical parameters sampled during the first time phase at the limiting resistor.
