Problems solved by technology
[0003] However, the problem of insufficient energy utilization efficiency caused by the limited energy density of lithium-ion batteries still needs to be solved.
More importantly, the operating temperature of lithium-ion batteries is -20°C-60°C, but at low or high temperatures, the battery will suffer from problems such as capacity attenuation and shortened lifespan, which hinders the development of lithium-ion batteries to a certain extent. further promotion of
Especially in low-temperature and high-cold environments, the capacity attenuation and performance degradation of lithium-ion batteries are more serious

Abstract
The invention discloses a hybrid power supply system and application thereof. The hybrid power supply system comprises a first battery and a second battery, wherein the first battery is connected withthe second battery through a coupling module; the coupling module comprises a heat exchanger and a battery switching module; the heat exchanger comprises a control valve, a heat exchange tube for a heat transfer fluid to flow and a phase change assembly arranged on the periphery of the heat exchange tube; and the battery switching module comprises a first control unit and a second control unit, the first control unit is used for controlling the control valve to open and close, and the second control unit is used for controlling the working conditions of the first battery and the second battery.
Description
technical field [0001] The invention relates to the technical field of battery systems, in particular to a hybrid power system and its application. Background technique [0002] The development of human social economy and the improvement of living standards have brought about a serious energy crisis, and at the same time, irrational energy utilization methods have also led to serious environmental pollution. At present, electric motors have gradually replaced diesel engines and have been widely used in human social life. Lithium-ion batteries have become the preferred power source due to their advantages such as high operating voltage. [0003] However, the problem of insufficient energy utilization efficiency caused by the limited energy density of lithium-ion batteries still needs to be solved. More importantly, the operating temperature of lithium-ion batteries is -20°C-60°C, but at low or high temperatures, the battery will suffer from problems such as capacity attenua...
