AI Technical Summary

Technical Problem

Existing integrated battery pack heating systems cannot effectively extend battery pack lifespan, resulting in reduced driving range at low temperatures.

Method used

By integrating components such as fuel heater, electric water pump, fuel tank, plate heat exchanger, three-way valve, and stainless steel tee, an integrated battery pack heating system is formed. Combined with temperature protection components and auxiliary heat dissipation components, precise temperature control and effective heat dissipation are achieved.

Benefits of technology

It extends the battery pack's lifespan, ensures that the battery capacity at low temperatures is close to that at normal temperatures, guarantees that the battery pack's range is not affected at low temperatures, and can also provide heating for the cab and defrost the windshield, thus improving the system's reliability and the battery's continuous and efficient operation.
