Description
Technical field
The present invention relates to battery technology field, more particularly to the low-temperature prewarming method of a kind of battery.
Background technology
In numerous Prospect of EVS Powered with Batteries types, lithium battery due to monomer voltage is high, have extended cycle life the advantages that
It enjoys great popularity.But the operating temperature range that lithium battery generally allows is -20 DEG C~60 DEG C, and its performance is by temperature shadow
Sound is larger, in particular, under cryogenic conditions, the charging capacity and service life of lithium battery can all be greatly lowered.It is generally believed that lithium
The reduction of ion battery performance under cryogenic is the diffusion due to solid electrolyte interface film lithium ion in the electrodes
And caused by surface charge transfer impedance etc..Therefore, it under cryogenic conditions, needs to heat lithium battery, after reaching suitable temperature
It recharges.
