Description
Technical Field
The utility model belongs to the field of new energy, and particularly relates to a heat dissipation, heat preservation, energy absorption and vibration reduction dual-function battery compartment structure.
Background
For a new energy automobile, as a lithium ion power battery is widely adopted as a power system of the new energy automobile, in order to obtain enough voltage and battery capacity to achieve enough driving power and endurance mileage, hundreds of batteries are generally integrated into a large battery module in a series-parallel connection mode. The performance of the power lithium ion battery is greatly influenced by temperature due to a large amount of heat generated by reaction heat, ohmic heat and polarized heat in the charging and discharging processes, the phenomena of battery overheating and temperature inconsistency are easily caused in the high-temperature condition and high-rate charging and discharging, the capacity and power attenuation of a battery monomer are caused, the capacity loss and the service life of a battery pack are shortened, and thermal runaway, even fire and explosion of the battery are caused in serious cases. Particularly, as the energy density of the lithium ion battery is further improved, the use conditions are more and more strict, and the heat generation amount of the lithium ion battery is also higher and higher. Temperature has a great impact on the performance, life and safety of lithium ion batteries. Meanwhile, the temperature inconsistency of the lithium ion battery can influence the service life of the battery pack, and the performance of the battery after being grouped is greatly reduced.
Meanwhile, the chemical reaction activity of the lithium battery is reduced rapidly under the low-temperature condition, the internal resistance of the battery is obviously increased, the voltage of the charging end of the battery is increased to the charging cut-off voltage, the chargeable electric quantity of the battery is reduced so that the dischargeable electric quantity of the battery is reduced, and the cycle life of the lithium battery is shortened. The principle is that when the lithium ion battery is charged at low temperature, lithium dendrite is easy to be separated out on the surface of a graphite cathode, and a diaphragm is punctured to induce short circuit in the battery, so that the capacity of the battery is attenuated, and the service life of the battery is reduced. Under the low-temperature environment, the charge and discharge performance of the lithium battery is obviously reduced, the charge and discharge of the battery become difficult, the starting and the charging of the electric automobile in the low-temperature environment are hindered, and the overall use performance of the electric automobile in the low-temperature environment is reduced.
The lithium battery bears the continuous action of vibration load in the driving process of the automobile, is easy to have serious extrusion deformation, punctures a battery monomer or causes the fracture of an electrical connection part, causes the leakage, the leakage and the short circuit of the battery, and further has the phenomena of spontaneous combustion, explosion and the like.
In a word, the performance of the lithium ion battery is very sensitive to temperature, and can only work normally within a certain temperature range, and performance parameters such as available capacity, charge and discharge peak power, cycle life and the like of the battery can be influenced by too low or too high temperature, and safety accidents can be caused under severe conditions.
At the present stage, three cooling methods of the lithium ion battery of the new energy automobile mainly comprise air cooling, phase change cooling and liquid cooling, and the three cooling methods have respective characteristics, wherein the air cooling method is a scheme that an air inlet (exhaust) grille structure is arranged in a power battery compartment, air convection is formed in the compartment by utilizing air pressure or forced air blowing formed in the driving process of the automobile, and heat generated by the power battery is exhausted by the convection air. The natural air-cooled type can form a certain cooling effect on the battery compartment through air convection, and has a simple structure and strong realizability. However, natural wind is greatly influenced by the ambient temperature, and when the external temperature is high, the temperature of the natural wind is also high, and the cooling effect is not good. Meanwhile, the whole cooling of the battery compartment cannot be accurately controlled, the temperature control speed is low, the precision is low, the temperature control consistency of the battery pack is poor, the structure is relatively large in space of the battery compartment, and a vehicle with a low battery capacity can play a certain temperature improvement role. The liquid cooling method is complex in system design, and meanwhile, when the liquid cooling system is designed, the problem of leakage of liquid is also considered, and corresponding energy-saving and consumption-reducing measures are required to be taken to reduce the power consumption of the pump. Although the phase change cooling does not need to be designed into a complex system, the heat dissipation can be realized only by a single circulation mode, and the heat dissipation effect is not ideal.
On the premise of not increasing the volume of the battery box body and the power consumption of the fan, a new air flow field is designed to improve the heat dissipation effect of air cooling, and the heat dissipation mode of the lithium battery for the vehicle, which can be practically applied, can be realized recently. But present ordinary type battery compartment has following characteristics: the structure is simple, the battery is compactly installed, and heat dissipation is not facilitated; secondly, the bottom has good heat dissipation, but the strength protection of the battery is reduced; the side wall of the battery compartment is totally closed, so that heat dissipation is not facilitated; and the battery compartment wall only has ribs and compartment wall thin plates, so that the collision energy absorption performance is insufficient.
