Problems solved by technology

However, directly using real battery packs to simulate various working conditions for detection will not only cause permanent capacity loss to the battery pack, but also have long charging and discharging times, unsuitable for long-term repeated cycle tests, difficulty in simulating fault states, and repeatability. Disadvantages such as poor controllability
Therefore, there are many shortcomings in using real battery packs to verify the feasibility of thermal management solutions, and it is necessary to consider using substitutes instead of real battery packs to verify the feasibility of thermal management solutions
[0004] The simulated heating system can simulate the heating of a real battery pack to provide convenience for battery pack testing. In the prior art, there is a programmable simulated heating system for battery thermal management testing, but its host computer and the simulated heating unit are connected through a communication bus, and Using an external power supply, due to the limitation of the space in the battery pack module, using the above-mentioned line connection leads to very complicated wiring, and requires real-time control by personnel on site, which is very inconvenient
In addition, the above circuit will also form a certain wind resistance and flow resistance to the air convection in the battery pack module, which will affect the heat generation simulation accuracy of the entire battery pack module.

Description

technical field [0001] The invention relates to a system for simulating heating of a battery pack and a control method thereof, in particular to a heating system and a control method for simulating a battery pack that communicates and controls wirelessly. Background technique [0002] The self-heating of the battery pack is an important factor affecting its life and safety. When the battery pack is discharged, a chemical reaction occurs inside the battery, generating a large amount of heat, which causes the temperature of the battery pack to rise. If the battery pack overheats for a long time, it will accelerate the aging process of the battery itself, shorten its life, and in severe cases, the battery will explode. Therefore, in the research on the performance of the power battery pack, it is necessary to consider the heat generation of the battery pack itself, conduct thermal management research on it, and formulate a corresponding thermal management test plan for it. ...
