AI Technical Summary
Existing battery modules using indirect water cooling methods suffer from limited cooling performance due to indirect contact with battery cells and require additional space for cooling devices, leading to energy density losses, and face challenges in preventing leakage of insulation cooling liquids through perforated sealing plates.
A battery module design where insulation cooling liquid directly contacts battery cells and electrical components, utilizing a channel spacer with cooling liquid channels and a sealing structure with O-rings to prevent leakage, including a front and rear sealing plate with inlets and outlets for efficient cooling and containment.
Enables efficient and rapid cooling of battery cells and electrical components while effectively preventing leakage of insulation cooling liquid, enhancing energy density and cooling efficiency.
