Description

Technical Field

[0001] This utility model relates to a portable heat and cold storage air conditioning device for electric vehicles, belonging to the field of energy storage technology. Background Technology

[0002] With increasing environmental awareness and the pursuit of sustainable transportation, the development prospects of electric vehicles are becoming increasingly broad. However, the issue of regulating the internal environment of electric vehicles under extreme temperatures has become a key factor restricting user experience, as both winter heating and summer cooling have a significant impact on vehicle range.

[0003] In winter, the driving range of electric vehicles is significantly reduced, mainly due to the performance degradation of lithium-ion batteries in low-temperature environments and the substantial energy consumption of the battery by the vehicle's heating system. Under low-temperature conditions, the chemical reaction rate inside the lithium-ion battery slows down, the electrolyte viscosity increases, leading to increased internal resistance, decreased lithium-ion migration rate and material conductivity, and a significant reduction in battery activity. At the same time, the demand for in-vehicle heating increases dramatically in winter, making the range anxiety issue for electric vehicles even more severe.

[0004] The problems are equally pronounced in the high temperatures of summer. To lower the interior temperature, the car's air conditioning needs to run continuously at high intensity, consuming a large amount of battery power. At the same time, high temperatures accelerate the aging of interior components, affecting the vehicle's lifespan, and the stuffy interior environment also severely impacts driving and passenger comfort.

[0005] Currently, some products on the market attempt to address these issues. Regarding heating, some electric vehicles are equipped with battery pack temperature control and heat dissipation devices, which provide cooling, insulation, and heating functions, but consume additional electricity during operation, failing to fundamentally solve the heating power consumption problem. Commercially available solid thermal storage bricks and similar products are generally bulky and inconvenient to carry, and rely on charging and onboard power, further increasing the burden on the vehicle's battery. Regarding cooling, existing onboard cooling systems rely entirely on the vehicle's battery for power, lacking an effective independent cooling solution and failing to alleviate range anxiety in summer. Summary of the Invention

[0006] This invention provides a portable heat and cold storage air conditioning device for electric vehicles. This device enables heating in winter and cooling in summer with zero power consumption during driving. It is safe, portable, requires no additional pump, effectively improves the driving comfort of electric vehicles in extreme temperatures, and significantly alleviates range anxiety in both winter and summer. In winter, the device uses a heat pipe radiator to conduct the heat stored in the hot water tank and the environmentally friendly heat storage ball upwards, and then blows the heat into the vehicle through a fan, without affecting the electric vehicle's range or interior thermal comfort. In summer, the device uses a heat pipe radiator to conduct the cold air from the ice-water mixture in the tank downwards, and then blows the cold air into the vehicle through a fan, regulating the temperature inside the passenger compartment without consuming additional battery power.
