A method for creating a map of at least one parking infrastructure. Unoccupied parking spaces inside the parking infrastructure are registered. Items of path information and items of environmental information are received by an external server unit. Items of path information are subdivided into path segments. The path segments are rectified by the external server unit. A loop recognition is carried out in order to create a geometrical map of the parking infrastructure. On the basis of the items of environmental information, occupied and unoccupied parking spaces along the path are acquired in order to ascertain unoccupied parking spaces inside the parking infrastructure. An external server unit and a system are also described.

A battery monitoring device includes a sensor device, which is electrically connectable to an automobile battery and may be placed thereon, and which is arranged to detect an operating variable of the battery. The battery monitoring device further includes a detection circuit, which is connected via a cable connection to the sensor device; and a data processing circuit, which is connected via a potential isolation circuit to the detection circuit. The potential isolation circuit provides isolation of the potential level of the detection circuit from a potential level of the data processing circuit for direct components.

Battery monitoring system

A method and an array for measuring a primary current in a primary conductor that is magnetically coupled to a secondary conductor via a ferromagnetic core. In said method, a voltage having a specific amplitude is applied to the secondary conductor such that a secondary current flows for reversing the magnetization of the ferromagnetic core; the secondary current is measured while the magnetization of the ferromagnetic core is reversed in order to obtain a first measured value; the polarity of the voltage is reversed such that a secondary current flows for once again reversing the magnetization of the ferromagnetic core; the secondary current is measured while the magnetization of the core is reversed in order to obtain a second measured value; the primary current is calculated in accordance with the first and the second measured value, the polarity of the voltage being regularly reversed at a certain sensor frequency that is continuously varied.

Current sensor arrangement for measuring currents in a primary conductor

A device for charging a battery system having a number of individual voltage sources situated in a series circuit is provided, which device uses a voltage source and a respective bypass associated with each of the individual voltage sources. A charge current Iis supplied from the voltage source via the bypasses to the individual voltage sources as a function of their charge condition.
