The nature of the power battery is deeply affected by the temperature factor, and the discharge efficiency changes with the temperature, thus affecting the performance of the electric vehicle. At present, the working temperature range of lithium batteries is -20 ℃ -60 ℃. In low-temperature environments, the range of electric vehicles will significantly decrease, and even more so, they will lose more than half of their range, making it difficult to charge "cold" batteries. Under high temperature conditions, without a suitable heat dissipation scheme, there will be significant differences in temperature across the battery pack, affecting the consistency of battery cells and causing a series of subsequent problems. The more serious one is that the battery overcharge leads to "Thermal runaway", which causes the electric vehicle to catch fire and explode.
And the thermal management system is in charge of how much heat the battery has. To put it simply, the thermal management system means that the battery pack will generate heat during the charging and discharging process due to the discharge efficiency, internal resistance, external environment and other factors. When the external environment temperature is low, it is necessary to ensure that the chemical substances in the lithium battery need to be heated before charging. Therefore, we should manage the thermal system of the battery pack, dissipate the unused heat, and heat the battery pack before charging at low temperature.
Thermal conductive material solutions focus on providing excellent heat conduction for high-energy batteries, thereby improving the overall performance of the battery.
Power batteries, as the "heart" of new energy vehicles, and adhesives are the "muscle tissue" that achieve long-lasting power of the "heart", which is crucial!
