Description
Technical Field
The invention relates to the field of automobile power batteries, in particular to a novel power battery temperature adjusting system and an automobile.
Background
It is known that automobiles are an indispensable vehicle in our modern society, and it is the vehicles that the distance is no longer an irreparable gap in people's lives. However, in the face of the increasingly depleted energy sources and serious environmental pollution, scientists have developed a new type of transportation vehicle, namely an electric vehicle, by using high technology. Compared with a fuel automobile, the electric automobile has many advantages, such as low noise, simple structure, convenient use and maintenance, little environmental pollution and high efficiency. Therefore, it is necessary to develop an electric vehicle.
Although the development of new energy vehicles mainly including electric vehicles is rapid, the further development of the new energy vehicles is still hindered by technical and management problems. Especially, the service life, the endurance and the electric energy storage capacity of the power battery need to be improved to be used as a power source of the pure electric vehicle, and the battery performance almost determines the fate of the whole pure electric vehicle industry. The battery cost, the driving range of one-time charging, the service life of the battery, the charging time and other technologies need to be improved.
One of the most urgent problems to be solved in the power battery is the temperature regulation of the power battery during the operation of the electric vehicle.
The temperature is one of the most important parameters for controlling in the power supply system of the electric automobile and also the most important parameter influencing the performance of the battery, and in all detection systems of the battery, the temperature must be noted because the temperature has a large influence on the performance of the battery, including the internal resistance, the charging performance, the discharging performance, the safety, the service life and the like of the battery.
The most important influence of temperature on a power supply system of an electric automobile is safety, and most of the electric automobiles in China currently use lithium batteries as main raw materials of power batteries. Because the working current of the power battery is large, the heat generation amount is large, and meanwhile, the battery pack is in a relatively closed environment, the temperature of the battery can be increased. At present, most of lithium batteries are composed of flammable and volatile non-aqueous solutions, and compared with batteries composed of aqueous solutions and electrolytes, the composition system has higher specific energy and voltage output and meets higher energy requirements of users. The nonaqueous electrolyte is flammable and volatile, and is soaked in the battery, so that a combustion source of the battery is formed. Therefore, the working temperature of the battery material is not higher than 60 ℃, but the outdoor temperature is close to 40 ℃ in summer, and the heat generated by the battery is large, so that the working environment temperature of the battery is increased, and the situation is dangerous if thermal runaway occurs. To avoid becoming "barbecued," it is important to dissipate heat from the battery.
The heat dissipation of the battery pack has two types, namely active and passive, and the efficiency of the battery pack is greatly different from that of the battery pack. The cost required for passive systems is relatively low and the measures taken are relatively simple. The active system architecture is relatively complex and requires more additional power, but its thermal management is more efficient.
Different heat transfer media have different heat dissipation effects, and the existing air cooling and liquid cooling methods are superior and inferior.
The main advantages of using gas (air) as the heat transfer medium are: the structure is simple, the weight is light, the ventilation can be effectively realized when harmful gas is generated, and the cost is lower; the disadvantages are that: low heat exchange coefficient with the wall surface of the battery, low cooling speed and low efficiency. At present, the application is more.
The main advantages of using liquid as the heat transfer medium are: the heat exchange coefficient between the battery and the wall surface of the battery is high, and the cooling speed is high; the disadvantages are that: the sealing performance requirement is high, the quality is relatively large, the maintenance and the repair are complex, parts such as a water jacket, a heat exchanger and the like are needed, and the structure is relatively complex.
The existing temperature control system can play a role in controlling the temperature of the battery pack. However, on one hand, the design of the electric vehicle is complicated, the cost of the electric vehicle is increased, and on the other hand, the additional cooling system also increases the energy consumption of the system, which is not in line with the theme of energy conservation and environmental protection of the electric vehicle. The conventional power battery temperature control system on the market is complex in structure, the temperature is not quickly and sensitively adjusted, and the safety and the heat dissipation efficiency are difficult to ensure by adopting gas as a medium. Under the condition, smaller temperature difference in the battery box body can be realized, the probability of occurrence of a consistent failure mode of the battery system caused by the temperature difference is further controlled, and the temperature regulating system which is used for controlling the probability of occurrence of the failure mode of the battery system caused by overhigh and overlow battery temperature and has simple structure and higher heat dissipation efficiency is particularly important.
