A battery system for an electric vehicle includes: a plurality of battery cells, each of the battery cells including electrode terminals; a busbar interconnecting the battery cells by contacting the electrode terminals; a battery housing enclosing the battery cells; and an electrically and thermally insulating cover element. The cover element covers the electrode terminals and the busbar such that the electrode terminals and the busbar are shielded from venting products exiting one or more of the battery cells towards the battery housing during a thermal runaway.

Battery system and vehicle including the battery system

The present invention refers to a battery module comprising a plurality of battery cells, each battery cell including a first terminal and a second terminal spaced apart and electrically isolated from one another, a housing including an upper housing part and a lower housing part assembled together to completely surround the plurality of battery cells, and a plurality of bus bars integrated in the upper housing part, wherein each of the plurality of bus bars is connected to one of the first and second terminals of at least two battery cells. The present invention further refers to a method of manufacturing the battery module, which is fast and easy and has a high tolerance for fluctuations in the battery cells height.

Battery module including a housing with integrated bus bar

The present invention relates to a battery pack including a frame profile with integral coolant circuit elements. The battery pack includes one or more battery modules, each comprising a plurality of secondary battery cells, a framework comprising a first frame profile and a second frame profile opposite to the first frame profile, and a liquid cooling circuit comprising one or more cooling plates being in thermal contact with the battery module.

Battery pack comprising frame profile having integral refrigerant circuit member

A battery pack for a vehicle includes: a battery module including a plurality of secondary battery cells; a carrier plate including an integral cooling channel structure having an opening at a side wall of the carrier plate; a liquid cooling circuit in thermal contact with the battery module; and a coupling member. The battery module is on the carrier plate. The integral cooling channel structure is part of the liquid cooling circuit, and the liquid cooling circuit includes a coolant distributor that is in a fluid-tight connection with the integral cooling channel structure at the opening at the side wall. The coupling member and the side wall of the carrier plate respectively include corresponding coupling elements to mechanically connect the coupling member and the carrier plate to each other, and the coupling member further includes a mounting bracket attaching the coolant distributor to the coupling member.

Battery pack for a vehicle

A battery pack for a vehicle is provided. The battery pack comprises: at least one battery module including a plurality of secondary battery cells, a metal framework for supporting the at least one battery module, the framework including a plurality of slots extending from a bottom side to an opposing mounting side of the battery pack, and an insert tightly positioned within each slot, the insert being made of a similar material as the framework and including a through-hole adapted for accommodating a fixation element.

Fixing element for a battery pack of a vehicle, and battery pack for vehicle including the same

A battery pack for a vehicle is provided. The battery pack includes: a plurality of battery modules and a liquid cooling circuit. At least one of the battery modules is arranged in two different levels from among a plurality of levels of the battery pack, the levels of the battery pack being adjacent each other in a vertical direction. The liquid cooling circuit is in thermal contact with the battery modules in the two different levels of the battery pack, and the liquid cooling circuit includes a bypass tube having an inlet opening at a highest point of the liquid cooling circuit in the vertical direction and an outlet opening within the liquid cooling circuit at a lower point of the liquid cooling circuit than the highest point of the liquid cooling circuit.

The present invention refers to a coolant distributor for a battery module housing with a hollow profile enclosing a coolant channel and a plurality of coolant junctions, each extending through a first portion of the hollow profile and providing a fluid connection between the coolant channel and a coolant port. The invention further relates to a battery module housing with a bottom plate comprising a plurality of embedded coolant ducts and a coolant distributor according to the invention that is welded to the bottom plate, such that each of the plurality of coolant ports is aligned with one of a plurality of inlet openings of the coolant ducts. The present invention further relates to a battery system housing, comprising a plurality of battery module housings according to the invention and a plurality of pipe couplings for interconnecting adjacent battery module housings, and to the pipe coupling.

Coolant distributor

A battery module includes a plurality of secondary battery cells; one or more cooling tubes formed of a metal material; and a cooling plate formed of casted aluminum, the cooling plate being cast around the one or more cooling tubes, the one or more cooling tubes being molded within the cooling plate.

Battery module including a cooling plate with embedded cooling tubes

A battery having a plurality of voltage-generating cells in which a plate-shaped intermediate element having elastic ribs at least on one side thereof is arranged at least between adjacent voltage-generating cells.
