Abstract

A device (200) for drying a battery (10; 20), characterized by a heating mechanism (230) for generating heat for regenerating a desiccant (260) by releasing absorbed moisture, said The desiccant is capable of absorbing moisture from the battery (10; 20); the opening (220) through which the moisture can pass from the battery (10; 20) to the desiccant (260); and the closure member (240), the closure The component can use the generated heat to close the opening (220). Battery (10; 20), battery system, vehicle and method for drying a 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 ...
