ELECTRIC OR HYBRID AUTOMOBILE VEHICLE WITH A COOLING SYSTEM FOR COOLING REMOVABLE BATTERY MODULES Russian patent published in 2022 - IPC B60L58/26 

FIELD: automotive industry.

SUBSTANCE: invention relates to an automobile vehicle with a modular battery system. The system comprises: a fixed battery module, a removable battery module and a battery management system. The stationary module is permanently installed on board the vehicle. The removable module contains: an outer shell, the first and second heat-conducting plates, a rechargeable battery pack, an inner circuit. The first heat-conducting plate is placed inside the outer shell. The rechargeable battery pack is placed inside the outer shell. The battery pack is mounted in contact with the first heat transfer plate. The inner loop continues inside the first plate and is filled with a heat exchange fluid. The second heat-conducting plate is configured to be in fluid communication with the inner loop so that the heat exchange fluid flows through it in the inner loop. The second heat-conducting plate is made with an outer surface outside the shell. The motor vehicle contains an auxiliary cooling circuit. The auxiliary cooling circuit has a direct expansion plate. The direct evaporation plate is attached to the vehicle and is configured to contact the second plate of the removable battery module when the removable battery module is installed on the vehicle.

EFFECT: increased cooling efficiency of the removable battery module.
