The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.

The invention relates to a battery system, in particular for a hybrid drive, comprising a housing and a plurality of battery cells arranged within the housing, said cells being combined to give a cell block, wherein a container having a variable inner volume is arranged between the cell block and at least one housing wall, by means of which container the cell block can be braced relative to the housing, wherein the container is filled with a curable or cured medium.

An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.
