battery charging test conditions at different ambient temperatures
At present, the battery is undoubtedly the most core and critical component in electric vehicles. Therefore, both the OEM and the battery factory need to conduct a comprehensive test of the battery. The characteristics of automotive lithium-ion power batteries are greatly affected by ambient temperature. In low temperature environment, the available energy and power attenuation is more serious, because long-term charging in low temperature environment, the life will be greatly shortened. In t...

Cooling and shrinking assembly freezer for metal parts and common assembly methods in the industry
In the cold shrink production of copper sleeves, bearings, etc., quick-freezing cryogenic boxes are widely used in mechanical assembly. Copper sleeve cooling shrink assembly cabinet variable temperature assembly method is to heat the hole or cool the shaft. When the diameter is larger or the interference amount is larger, the parts will be damaged if assembled at normal temperature. In this case, the method of heating and containing the parts or cooling the contained parts should be used for ...

Chemical reaction exothermic or endothermic temperature dynamic compensation system
In the chemical laboratory, pilot plant and reaction process, temperature control requires the use of dynamic temperature control systems. When controlling the reactor, the exothermic and endothermic reactions must be compensated with high speed and reliability. The dynamic compensation of exothermic or endothermic chemical reactions poses a greater challenge to temperature control systems. Especially if the reaction occurs in an extreme temperature range, the temperature control system must ...
