Description
Technical field
The utility model is related to technical field of lithium batteries, are to be related to a kind of lithium battery safeguard protection system more particularly
System.
Background technology
Li-ion batteries piles be usually by several lithium ion batteries by the way of series, parallel it is tightly packed after prepare and
At, the Li-ion batteries piles in the case where the abuse conditions such as being squeezed or puncturing, short circuit occurs for inside battery, leads to internal battery pack
Energy moment largely discharges, and thermal runaway occurs, causes the safety problems such as catch fire or explode.
Currently, main Improving Measurements include：One, it by way of increasing the intensity of lithium ion battery pack outer case, reduces
Inside lithium ion cell is squeezed or punctures when slight impact.Two, Li-ion batteries piles are sealed, is completely cut off during battery catches fire
The source of the external oxygen needed or further increase fire retardant in the seal, when battery catches fire inhibits burning.But for
The power battery pack collision occurred in high speed motions, can not effectively slow down external huge energy Impact Problems.Both
Mode can fail, and the safety of battery cannot be effectively ensured.
The safety problem of lithium ion battery be after all lithium ion battery electric energy and chemical energy it is out of control.Wherein electric energy wink
Between discharge ohm heat of generation and be the inducement of chemical thermal runaway, therefore need to carry out safeguard protection to lithium battery, be released effectively battery
Internal energy can enhance the safety of battery.
