Description
Technical field
Electric automobile and energy-storage system the present invention relates to a kind of battery system, with the battery system.
Background technology
Existing power lithium battery cell system, energy-storage system etc. are single current supply circuit framework, as shown in Figure 1, by single only
Vertical battery pack composition, it will be the disadvantage is that, some cells burst will trigger adjacent cell burning, and produce chain reaction, finally
Whole battery pack is set to burn, a large amount of cells bursts will become uncontrollable, and will produce high risks.Therefore, when some battery goes out
Existing overcharge or overdischarge, and when environment temperature is below or above operating temperature section, whole current supply circuit is all necessary
Open circuit, occurs to avoid accident, this to protect the efficiency for reducing battery system, also reduces vehicle course continuation mileage.Single loop
Construction for electricity influences the reliability and security of battery system.
On battery pack structure, using rectangular cell as representative, existing battery pack structure is to be put together at battery together
In one babinet, since a large amount of batteries are placed in same babinet, arranged closely between battery, once some battery cell is sent out
Raw burning, will trigger adjacent cells burst, then produce chain reaction, cause battery pack out of control safely, therefore, existing battery
Pack arrangement lacks reliability and security.Meanwhile the heat management system of existing battery pack structure is extremely complex, various heat dissipation knots
Component increases the volume and weight of battery pack again.
In addition, the temperature control system in existing power lithium battery cell system is at the same time using two sets of systems of cooling system and heating system
System.In cooling system, open type battery pack structure uses gaseous exchange mode, and heat between battery is extracted out, battery is reduced with this
Temperature in bag；Enclosed cell pack arrangement uses coiled pipe liquid cooling mode, and heat between battery is conducted to coiled pipe
Liquid, the cooling device outside battery pack makes liquid cooling, then flows back in the coiled pipe of battery pack, restarts to circulate.Heating
In system, open type battery pack structure uses resistance wire heating system, improves the temperature of battery in battery pack；Enclosed cell bag
In structure, liquid is heated by the heating unit outside battery pack, then flows back in the coiled pipe of battery pack, the liquid in coiled pipe
Heat is conducted to battery by body, then flows back to the heating unit outside battery pack by coiled pipe, restarts to circulate.
It can not accomplish waterproofing grade using with extraneous gas convection type mode, battery pack, convection current can accelerate to wrap interior battery
Burning；Using closed liquid circulation mode, snakelike pipe component processing and installation is difficult, takes the inner space of battery pack, leakage
Liquid causes short circuit, triggers severe safety accident.It is two sets to be additionally, since the cooling system of existing battery system and heating system
Different subsystems, cooling system either use gas or liquid cooling mode, all increase the volume of battery pack, air passage
Or pipeline configuration is complicated, refrigerating efficiency is low.
