At many individually small-sized partitions；Storage has a battery module in each partition, and it is quick-fried can to effectively reduce battery in this way
Fried or burning the condition of a disaster diffusion or sprawling, play the purpose of explosion-proof flame-retardant.In addition, being opened in each partition comprising an open circuit
Close, this switch can disconnect the battery module in partition from entire battery system, and with battery module in adjacent partition
It disconnects, prevents single battery from damaging and cause the damage of entire battery system；In addition, containing nonconducting cooling medium in partition
Or solution, the heat that battery generates can be absorbed by nonconducting solution, guaranteed that battery is in normal operating temperature, prevented battery
The generation of overheat or explosion, it is ensured that the work that entire battery system can be safer, more reliable.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is schematic diagram of the invention；
Fig. 2 is schematic structural view of the invention.
Specific embodiment
Referring to Fig.1, have fire-retardant, explosion prevention function, the lithium battery system suitable for high-energy density, high power density be
On the basis of existing battery system, increase the following contents: the fire-retardant of battery system, Explosion-proof Design and battery system are fire-retardant, explosion-proof
Control strategy.
Referring to Fig. 2, having fire-retardant, explosion prevention function high-energy, high power density lithium battery system includes several batteries
Module, each battery module are mounted in partition, and the battery module in partition is connect by disconnect switch with external electrical,
Partition is sealing structure and is connected to nonconducting cooling medium by liquid valve.Battery system mechanical structure is using sealing partition
Design, entire space are divided into many individually small-sized partitions；Storage has a battery module in each partition, this
Sample can effectively reduce the diffusion or sprawling of battery explosion or the condition of a disaster of burning, play the purpose of explosion-proof flame-retardant.In addition, each separates
In all include a disconnect switch, this switch can disconnect the battery module in partition from entire battery system, and with phase
Battery module also disconnects in neighbour's partition, prevents single battery from damaging and causes the damage of entire battery system；In addition, partition includes
There are nonconducting cooling medium or solution, the heat that battery generates can be absorbed by nonconducting solution, guarantee that battery is in normal
Operating temperature, prevent battery from overheating or the generation of explosion, it is ensured that the work that entire battery system can be safer, more reliable.
Wherein, the partition is communicated with vent valve.When gas pressure is greater than the set value in partition, exhaust valve is opened,
High pressure gas in release partition prevents explosion to reduce partition internal gas pressure.
Wherein, the partition is closely joined together one by one, forms an organic close entirety；And it is nonconducting
The cooling medium that insulate is internal full of partition, so that guaranteeing that battery in cover is full and uniform is quickly obtained cooling, is guaranteeing battery just
Often work, effectively prevent the generation of thermal explosion.
In addition, it is described partition be divided into shell 1, absorbing energy layer 2 and flame-retardant layer 3, absorbing energy layer 2 is middle layer, using spraying or
Energy-absorbing material addition is coated in partition inner surface；Innermost layer is flame-retardant layer 3, is being inhaled using spraying or coating fire proofing addition
It can layer surface.Absorbing energy layer can absorb the impact energy generated when battery explosion, and flame-retardant layer can prevent to separate interior cells burst the condition of a disaster
Sprawling, achieve the effect that fire-retardant.Flame retardant plastics, flame-retarded resin or the metal-back manufacture of hard can be used in the shell.
It is designed based on fire-retardant, anti-explosion battery service system, battery system is divided into air pressure in battery system using control strategy
