What is battery thermal management? What are the main functions of the 12V23A battery pack thermal management system?
What is battery thermal management?
Battery thermal management is based on the impact of temperature on battery performance, combined with the electrochemical characteristics and heat generation mechanism of the battery, based on the optimal charging and discharging temperature range of the specific battery, through reasonable design, based on materials science, electrochemistry, heat transfer It is a new technology based on multidisciplinary fields such as science and molecular dynamics to solve the problem of heat dissipation or thermal runaway caused by the battery operating at too high or too low temperature to improve the overall performance of the battery.
Necessity and development trends of thermal management of power 12V23A battery packs:
Compared with the immediate concerns caused by overcapacity, the safety issues of 12V23A battery packs, especially the long-term concern of battery thermal management, do not seem to have attracted enough attention. As the temperature decreases, the discharge performance of the 12V23A battery pack decreases significantly, the discharge platform decreases significantly, and the discharge capacity decreases significantly. When the temperature drops to -30°C, the discharge capacity of the 12V23A battery pack is 87.0% of the room temperature discharge capacity. If used in a low temperature environment for a long time, or in an ultra-low temperature environment of -40°C, the power supply will be frozen and cause permanent damage. Therefore, thermal management of 12V23A battery packs is particularly necessary.
Currently, there are two main methods for low-temperature heating of lithium batteries. One is variable resistance heating, including PTC heating plates and carbon film heating plates; the other is constant resistance heating, including silica gel heating plates, PI heating films, and epoxy plates. Heating film.
Experimental data shows that after charging the energy-type 12V23A battery pack at 1C for 45 minutes in an adiabatic environment, the temperature rise inside the cell is above 10 degrees Celsius, and some are even above 15 degrees Celsius. Experiments on fully charged battery cells show that in an adiabatic environment, when the battery core is heated to 50 degrees by an external source, self-reaction begins inside the battery core, and the temperature begins to rise. Although the rise is slow, the final result is combustion. Invalid.
The 12V23A battery pack thermal management system has the following five main functions:
①Accurate measurement and monitoring of battery temperature
②Effective heat dissipation and ventilation when the battery pack temperature is too high
③Rapid heating under low temperature conditions
④Effective ventilation when harmful gases are generated
⑤ Ensure the uniform distribution of the temperature field of the 12V23A battery pack
