Energy storage device with i.e. lithium ion rechargeable battery for e.g. electric vehicle, has heat guide passage guiding medium at moderate temperature and in thermal contact with support element

摘要

The device has electrical contact arresters (120A, 120B) protruding from an electrically insulating sheath (110) of a battery (100). A partially thermally conductive material includes an extensive support element, which is arranged such that a portion of the sheath is arranged between the support element and contact arresters. A heat guide passage is provided for guiding medium i.e. refrigerant, at moderate temperature. The passage thermally contacts with the support element. The element includes a surface, which is aligned within tolerance range parallel to a surface of the arresters. An independent claim is also included for a method for manufacture of an energy storage device.
