Technical Field
The present invention relates to a battery charging system.
The invention also relates to a battery device for a battery charging system.
Background
Known battery chargers typically include an AC/DC stage and a galvanically isolated (galvansch getrennte) DC/DC stage. Due to the electrical isolation, the DC/DC stage may be divided into a primary side and a secondary side. The AC/DC stage rectifies the AC voltage (energy consumption) drawn from the supply network into a DC voltage. The subsequent DC/DC stage generates the voltage required or suitable for the battery from the rectified alternating voltage.
Batteries typically include a battery management system for protecting and monitoring the battery, for example, to avoid excessive amperage during battery charging, and the like. Here, not only the battery management system but also the secondary side of the charging device have partially the same functionality.
