Embodiment Construction

[0060] figure 1 Shown is a schematic side view of a battery 10 with a device 200 for drying the battery 10 in a dehumidified state according to one embodiment of the invention.

[0061] The battery 10 includes a case (battery case) 110 and one battery cell 120 or a plurality of battery cells such as two, three, four or more battery cells provided in the battery case 110 in. This battery cell can be arranged in a battery module or a battery pack. A plurality of battery cells may be arranged in a battery module, a plurality of battery modules, a battery pack or a plurality of battery packs. The battery 10 may also include a temperature regulation device for temperature regulation, ie cooling or heating, of the battery cell 120 or a plurality of battery cells, and connecting pipes (hoses) for introducing or leading out a temperature regulation agent.

[0062]The battery 10 also includes a drying device 200 . The drying device 200 may include a housing 210 . The drying device...

Abstract

A device for dry battery (10, 20) (200), whose character is: used to generate heat heating institution (230), used to absorb through release water to regeneration of desiccant (260), described in the desiccant can absorb moisture from the battery (10, 20). Opening (220), water can be described through the opening from the battery (10, 20) reach the desiccant (260); And closed parts (240), described in the enclosed parts can use the heat generated to closed openings (220). Battery (10, 20), battery system, vehicle and method for dry battery (10, 20).

Description

Background technique [0001] It is foreseeable that, as rechargeable energy accumulators (EES), both stationary applications, such as for wind energy plants, and mobile applications, such as for electric vehicles (Electric Vehicle EV) or hybrid vehicles (Hybrid Electric Vehicles HEV), Modern battery systems, for example with lithium-ion batteries, lithium-polymer batteries or nickel-metal hybrid batteries, are increasingly used. [0002] Lithium-ion batteries consist of a positive electrode (cathode) and a negative electrode (anode), which are reversibly loaded (inserted) with lithium ions (Li+) during charging or unloaded (removed) with lithium ions during discharge. Lithium-ion batteries have high energy density and low self-discharge. [0003] Such battery systems have to meet high requirements with regard to usable energy content, charging / discharging efficiency, reliability, lifetime and undesired loss of capacity due to frequent partial discharges. [0004] The battery ...
