Embodiment 1

[0053] The present invention proposes a method for regulating the temperature inside an electric vehicle, comprising the following steps:

[0054] When the battery is charging and the battery is charged to the set state of charge, according to the remaining charging power of the battery and the time difference from the set time of the car at this time, the charging current of the battery within the time difference is calculated, and according to the charging current The battery is charged, and the moment when the battery is fully charged is the set car use time.

[0055] During the charging process of the battery within the above time difference, check whether the ambient temperature in the car reaches the temperature at which the air conditioner is turned on. If it reaches the temperature, turn on the air conditioner to achieve charging while the battery is charging while the air conditioner is preheating or cooling. , the charging is completed, and the preheating or precooli...

Embodiment 2

[0068] The invention designs an electric vehicle interior temperature adjustment system, which is suitable for low-temperature and high-cold regions, realizes the combination of vehicle heating, battery heating and charging process, and completes the process of vehicle heating, battery heating and heat preservation. Such as figure 1 As shown, the temperature regulation system includes vehicle terminal, battery management system, vehicle controller, power battery system and air conditioning controller. Among them, the vehicle-mounted terminal is connected to the battery management system through the CAN network, and the battery management system is connected to the vehicle controller through the CAN network. Similarly, the vehicle controller is connected to the air-conditioning controller through CAN communication, and the battery management system is also connected to the power battery system by sampling. Connect the air conditioner controller through the high voltage wire.

Abstract

The invention relates to an electric automobile and an in-automobile temperature adjusting method and system thereof. When a battery is charged, according to the residual charging electric quantity condition of the battery and the time difference of the automobile using time, the charging current for charging the battery in the time difference is calculated and distributed, and preheating or refrigerating of the air conditioner is performed while the battery is charged; and finally, when the automobile using time set by the automobile owner is reached, charging is completed, and preheating orpre-cooling of the air conditioner is completed. Adjustment of the environment temperature in the automobile is completed before a user uses the automobile, and the using comfort of the electric automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle thermal management, and in particular relates to an electric vehicle and a method and system for adjusting the temperature inside the vehicle. Background technique [0002] Automobile is an important means of transportation in modern society, and it is also an important pillar industry of the national economy. With my country's sustained and rapid economic development and accelerated urbanization, the demand for automobiles will continue to grow for a long period of time in the future, and the resulting energy shortage and environmental pollution will become more prominent. Accelerating the cultivation and development of energy-saving vehicles and new energy vehicles is not only an effective way to alleviate the pressure on energy and the environment, but also an urgent task to promote the sustainable development of the automotive industry. With the release of the "Energy Conservation an...
