Abstract
A battery system having at least a pair of battery modules, each battery module having a base plate and a cell stack secured on a base surface of the base plate. A first offset is arranged on a first side of the base plate and a first section is arranged on a second side opposite the first side. First threaded holes are arranged in the first offset and in the first section, parallel to the direction of extent of the first offset and of the first section. The battery modules are connected to one another via the auxiliary frame by screwing into the first threaded holes through through-holes arranged in the auxiliary frame.
Claims20
A battery system, comprising:
- at least two battery modules each having a base plate and a cell stack on a base surface of the base plate, the base plate having a first offset arranged on a first side of the base plate and a first section arranged on a second side opposite the first side, first threaded holes arranged in the first offset and the first section, and which lie parallel to a direction of extent of the first offset and the first section;
- and
- an auxiliary frame having auxiliary frame through holes which correspond to the first threaded holes to connect the battery modules to one another.
A battery system, comprising:
- at least two battery modules each having a base plate and a cell stack on a base surface of the base plate, the base plate having a first offset arranged on a first side of the base plate and a first section arranged on a second side opposite the first side, first threaded holes arranged in the first offset and the first section, and which lie parallel to a direction of extent of the first offset and the first section, second threaded holes arranged in the first offset, and which lie perpendicularly to the base surface, and second through-holes arranged in the first section, and which lie perpendicularly to the base surface;
- a first auxiliary frame arranged at a first end of the battery modules and having first auxiliary frame through holes which correspond to the first threaded holes to connect the battery modules to one another;
- a second auxiliary frame arranged at a second end opposite the first end of the battery modules and having second auxiliary frame through holes which correspond to the first threaded holes to connect the battery modules to one another;
- and
- a housing having a housing shell, a housing cover, housing through holes and housing threaded holes which respectively correspond to the second through holes and the second threaded holes to connect the battery modules to the housing shell.
A battery system, comprising:
- at least two battery modules each having a base plate and a cell stack on a base surface of the base plate, the base plate having:
- a first offset extending from a first side of the base plate;
- a first section arranged on a second side opposite the first side;
- first threaded holes arranged in the first offset and the first section, and which lie parallel to a direction of extent of the first offset and the first section,
- second threaded holes arranged in the first offset, and which lie perpendicularly to the base surface,
- second through-holes arranged in the first section, and which lie perpendicularly to the base surface;
- a first web which extends upwardly from the first offset and perpendicularly to the base surface of the base plate;
- an auxiliary frame to connect the battery modules to one another;
- and
- a housing connected to the battery modules, the housing having a housing shell and a housing cover.
