Method for regulating temperature of electric car

Abstract

The invention discloses a method for regulating the temperature of an electric car, and belongs to the field of car heating and cooling. The method aims at fundamentally solving the problems that an electric car air conditioner consumes electric energy of a battery, and the battery is short in high-temperature service life, low in low-temperature capacity and low in charging speed. In the parking process, an outer power source supplies power to a refrigerating / heating unit, the cold end or hot end of the refrigerating / heating unit is connected with a car inside environment unit, a cold storage / heat storage unit and a battery and refrigerates / heats the car inside environment unit, the cold storage / heat storage unit and the battery, and the hot end or cold end is connected with a chassis car body outside component for heat radiation or absorption. In the car running process, the cold storage / heat storage unit or the battery releases heat cold or heat into the car inside environment unit. Water is adopted as a medium of the cold storage / heat storage unit. Braking kinetic energy is recycled through an axle and allows the refrigerating / heating unit to continue to carry out refrigerating or heating . The method is used for the electric car and the like, and a remote control unit can enable the temperature in the car to be comfortable and achieve cold and heat storage in advance through the operating unit. When the air conditioner operates, the electric energy of the battery is rarely used. The battery can be helped to be fast charged, the service life is prolonged in summer, and the capacity of the battery is increased in winter. The electric car can be popularized to regions with various climates more easily.

Description

technical field [0001] The invention belongs to the field of vehicle heating, cooling and ventilation, and in particular relates to a method for regulating the temperature of an electric vehicle. Background technique [0002] In recent years, electric vehicles, including closed electric tricycles, electric scooters, electric vehicles, etc., have been popularized and developed in the market with the advantages of being affordable and convenient. A set of "battery-electric control-motor" drive system is installed in the existing pure electric vehicle. When parking, the battery is charged with the electric energy of the external grid power supply, and the kinetic energy of the vehicle can be recovered to the battery when decelerating and braking; while the gasoline-electric hybrid Automobiles combine the "battery-electronic control-motor" system with the traditional "fuel tank-carburetor-engine" system. The motor replaces or assists the engine in some cases, and the engine seld...
