Description
Technical Field
The invention relates to the field of civil aviation passenger plane batteries, in particular to an all-weather thermal management device for a passenger plane storage battery.
Background
With the development of civil aviation industry, the storage battery plays a crucial role in the safe flight of civil aircrafts, and attracts more and more attention of people. The storage battery is an emergency power supply and an auxiliary standby power supply on the civil aircraft, and has the main functions of: when the main generator and the emergency generator of the airplane can not supply power, supplying power to key equipment necessary for ensuring the safe flight of the airplane; as a starting power source for starting the main engine or the auxiliary engine of the airplane; and the power supply is used for short-time maintenance before and after navigation. However, the airplane needs to go and back continuously in different areas of the environment, and meanwhile, the conditions of shutdown, takeoff and cruising determine the complexity and diversity of the environment to which the airplane faces, so that the battery on the airplane also follows the experience of the variable environment.
However, the battery has a strong sensitivity to temperature, and its optimum operating temperature range is 15 ℃ (TL) to 35 ℃ (TH). In a high-temperature state of the battery, a large amount of chemical heat generated in the charging and discharging process is not released in time, so that the temperature of the battery is rapidly increased and rapidly exceeds the critical temperature of thermal runaway of the battery core, and the diaphragm, the electrolyte, the SEI film and the like are affected, so that the temperature is further increased, the service life of the battery is shortened, and even a fire accident occurs. When the temperature of the battery is too low, the performance of the battery is also affected, because when the temperature of the battery is too low, the active material in the battery is in a dormant state, the internal resistance is increased, and further the voltage is rapidly reduced, which is represented as that the battery module cannot be charged and the SOC is rapidly reduced, and the battery can be overdischarged due to severe low temperature under an extremely cold condition, so that the time limit that the battery can maintain the safe working capacity is greatly shortened. Therefore, to prevent the adverse consequences of excessive or low temperature of the battery, efficient and sensitive battery thermal management methods must be designed to maintain optimum operating temperatures for passenger aircraft batteries around the clock.
The analysis shows that the battery needs to be well cooled and heated in a heat preservation way, so that the safe and stable operation of the airplane is guaranteed. However, the existing research often considers the heat dissipation and heat preservation of the battery as an opposite contradictory relation, only focuses on one performance, and as a result, the existing battery generally has regional limitations and cannot meet all weather environments. In fact, heating and heat dissipation are a pair of opposite and unified targets, and the heating and the heat dissipation can be organically combined through innovation of design concepts.
