Problems solved by technology

[0005] When both the cabin and the battery have cooling requirements, the compressor cannot simultaneously control the air intake temperature of the cabin and the temperature of the battery coolant, which will inevitably cause the temperature on one side to be unable to be accurately guaranteed; if the temperature of the passenger compartment is guaranteed, the battery temperature will not be good. If the temperature of the battery is guaranteed, the comfort of the passenger compartment cannot be guaranteed

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Please refer to figure 1 , figure 1 Schematic diagram of the cooling system for the cabin and battery.

[0022] The control method for cabin and battery provided by the present invention is based on figure 1 cooling system shown.

[0023] Such as figure 1 As shown, the cooling system for the cabin and battery includes a compressor 10 , a condenser 20 , an evaporator 30 , a cooler 40 , a pump 50 and a battery 60 .

[0024] Wherein, the outlet of the compressor 10 is connected with the inlet of the condenser 20, and the outlet of the condenser 20 is divided into two branches, one of which is connected with the inlet of the evaporator 30, and the other is connected with the refrigerant inlet of the cooler 40, and evaporates ...

Abstract

The invention discloses a control method used for a vehicle cabin and a battery. The control method includes setting a current target evaporating temperature and a current target coolant temperature according to current environmental parameters when both a vehicle cabin and a battery have cooling demands; obtaining the actual evaporating temperature of the outlet of an evaporator, and adjusting the rotating speed of a compressor according to the actual evaporating temperature and the current target evaporating temperature until the actual evaporating temperature achieves the current target evaporating temperature; and obtaining the actual temperature of liquid coolant in a battery cooling circuit, and adjusting the refrigerant flow rate in the battery cooling circuit according to the actual temperature of the liquid coolant and the current target coolant temperature until the actual temperature of the liquid coolant achieves the current target coolant temperature. The control method can simultaneously perform accurate control when both the vehicle cabin and the battery have cooling demands, so that the air-out temperature of the vehicle cabin and the coolant temperature of the battery can be guaranteed, the comfortableness of the vehicle cabin can be enhanced, and the service life and endurance capabilities of the battery can be ensured.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a control method for a cabin and a battery. Background technique [0002] For new energy vehicles, especially pure electric vehicles, the battery module is the source of power for the vehicle, and the performance and life of the battery directly affect the battery life of the vehicle. [0003] Under normal circumstances, the battery will generate heat in the discharge state. When the heat is too high and the battery temperature exceeds the normal operating temperature range, the battery performance will be reduced and the service life of the battery will be reduced. Therefore, it is necessary to cool the battery to improve Battery life and endurance. [0004] For automobiles, there is also a need for cooling in the cabin. At present, the cooling system of the cabin and the battery are integrated, that is, a refrigerant pipeline connected in parallel with the evaporat...
