Abstract: This thermal management apparatus for energy storage batteries in cold regions combines a battery enclosure and a diesel-fired circulation heater. The enclosure comprises an enclosure body with dual-layer outer/inner housings separated by a first vacuum insulation layer, and a cover mounted atop the enclosure body containing a second vacuum layer. The inner housing incorporates a water reservoir interlayer connected to two upper-mounted delivery pipes. The cover features water delivery ports fitted with adapters coupling to the pipes, along with a cable routing hole accessing the inner housing. The heater forms a closed hydraulic loop by connecting its inlet and outlet to respective adapters. A temperature sensor installed on the inner housing's interior wall is linked to the heater for operational control. The dual vacuum insulation layers synergize with the circulating water system to maintain optimal battery temperature while minimizing heat dissipation.
