A kind of lithium battery module of electric vehicle.
Background technology
With the raising of new-energy automobile volume of production and marketing, the safety problem of new-energy automobile has caused the pass of industry and government
Note and anxiety；There are six electric vehicle fire events, on January 1st, 2016, a tesla in Tesla (CS) Koncern, Podebradska 186, Praha 9, Czechoslovakia of the U.S. in 2015
Model S in one of Norway super charging station charging the 7th time it is on fire, also there is serious electric motor coach combustion incident in the country.
Power battery be with security application technology in groups the development of current new-energy automobile key technology.
Lithium battery is electric energy carrier, but the isolation of the positive and negative anodes diaphragm of the carrier is mounted in the metal shell for having electrolyte
In, the problems such as diaphragm and electrolyte are inflammable thing, and such impurity, metal crystallization, diaphragm injury and technique manufacture, easily produces
Raw internal short-circuit of battery causes the release of electric energy and chemical energy double energy, occurs " thermal runaway ", burning and explosion.Now this
Process is also unpredictable, test reproduction and control, current battery management system lose power supply in itself when short circuit occurs, even if
It is also helpless in monitoring.Even such fire event a ten thousandth is caused by internal short-circuit of battery, the life to people
Property can all generate heavy losses, must do the Curve guide impeller of electrokinetic cell system with theory according to stringent prudent attitude thus.
Due to the above-mentioned attribute of battery core, using standardization, 18650 batteries that energy is small, comparatively safe, become safer
Technology path；Multi-parallel can be handled well in groups with administrative skill, internal short-circuit is strictly handled, strengthen safeguard construction design, is exhausted

The electric vehicle of Si La companies；The former ventilation, heating, cooling etc. are had any problem；Tesla (CS) Koncern, Podebradska 186, Praha 9, Czechoslovakia of the latter U.S. employs liquid cooling,
Complicated expensive, ventilation condition is poor, is also inconvenient to repair and replace.
For this purpose, using the lithium dynamical battery of cylindrical standard as row, a kind of lithium battery module of multi-parallel has been invented in this case
Assembly, the module assembly ensure that the monomer of lithium battery when there is internal short-circuit, have safety when colliding, in air duct slats
Safety is also provided in terms of part, electrical connection condition, process, assembling condition, material selection；With in liberal supply, safety
Condition convenient, cheap, conducive to popularization provides support for shaping up for electric vehicle.
