The battery pack provided by the invention dispenses with an air inlet/outlet, so as to easily meet the requirement of protection grade higher than IP65; the battery pack dissipates heat uniformly through heat dissipation by the battery box body, heat is conducted to the battery box body very quickly and is dissipated by high-speed flowing air on the outer side of the battery box body, and a fin heat-dissipation structure is additionally arranged on the battery box body, so that the battery pack has relatively good heat-dissipation performance; the structure is simple and easy to realize, additional space for a heat dissipation medium is not needed, and the volume energy density of the battery pack is high.
Description
Technical field
?the present invention relates to a kind of batteries of electric automobile group, particularly a kind of heat radiating type batteries of electric automobile group.
Background technology
At present, because electric automobile requires voltage and the capacity of battery pack higher, cell needs hundreds and thousands of connection in series-parallel to use can reach instructions for use.In this compact arranged situation, battery pack, in charge and discharge process, can produce a large amount of heat, causes battery pack temperature to rise.At present, the best serviceability temperature of ferric phosphate lithium cell, at 0-45 DEG C, if excess Temperature can affect battery pack serviceability, and also obviously shortens useful life, and severe patient can cause potential safety hazard.
The radiating mode that prior art adopts mainly uses air-cooled or liquid cooling.Air-cooled shortcoming: the one, inlet and outlet is set, more than the degree of protection of battery pack cannot reach IP65, the battery pack generation potential safety hazard of easily intaking; The 2nd, the temperature distributing disproportionation in battery pack is even, and the temperature difference is larger, causes local cell capacity attenuation very fast, affects battery performance; The 3rd, the heat conductivility of air is lower, conductive coefficient 0.023W/(mk) left and right, the radiating efficiency of battery pack is lower.Liquid-cooling heat radiation effect is better, but also has a lot of shortcomings: the one, and internal structure complexity, pipeline gathers, and potential safety hazard easily occurs; The 2nd, structure takes up room, and battery pack volume is large, causes the energy density of battery pack to reduce; The 3rd, battery weight is large, and structure parts are many, and cost is higher.
Summary of the invention
?the invention provides a kind of heat radiating type batteries of electric automobile group, it comprises cell, modular cartridge and Battery case, described cell is located in described modular cartridge and is contacted with described modular cartridge face, and described modular cartridge is located in described Battery case and with described battery case dignity and is contacted;
Shell, modular cartridge and the Battery case of described cell is that heat-conducting is made, and between the shell of described cell and described modular cartridge, insulate and is connected.
