Embodiment 1

[0052]Embodiment 1: When the fast charging is permitted, and the delayed charging is set, it will enter the delayed waiting; otherwise, this step will be skipped. While waiting for the fast charging delay, the air conditioner is not turned on, and if the timer expires, it is allowed to enter the fast charging.

[0053] When the air conditioner is turned on while waiting for delayed fast charging, if the SOC is not lower than 11%, the high-voltage battery will drive the air conditioner. When the air conditioner is turned on while waiting for the delayed fast charge, if the SOC is lower than 11%, the handbrake will be checked: if it is not pulled up, the prompt code "Please pull the handbrake" will be sent, if it is not pulled up within 10 minutes, it will not be allowed Charging; if the handbrake has been pulled up or pulled up in time, request to enter the fast charge in advance.

[0054] When requesting fast charging in advance, if the last step is that the SOC is lower than...

Embodiment 2

[0056] In Embodiment 2, when slow charging is permitted, it enters into delayed waiting when delayed charging is set, otherwise skips this step. While waiting for the slow charge delay, the air conditioner is not turned on, and if the timer expires, it is allowed to enter the fast charge.

[0057] When the air conditioner is turned on while waiting for delayed slow charging, if the SOC is not lower than 13%, the high voltage battery will drive the air conditioner. When the air conditioner is turned on while waiting for delayed slow charging, if the SOC is lower than 13%, the handbrake will be checked: if it is not pulled up, the prompt code "Please pull the handbrake" will be sent, and if it is not pulled up within 10 minutes, it will not be allowed Charging; if the handbrake has been pulled up or pulled up in time, request to enter slow charging in advance.

[0058] When requesting early slow charging, the air conditioner is suspended and waits for the charging system to res...

Abstract

The invention discloses an electric vehicle charging coordination control method and the electric vehicle. Including receiving the charging instruction to enter the charging permission state; judging whether to delay charging; delaying the charging waiting period, receiving the air conditioner start signal, judging whether the battery SOC exceeds the threshold, if it is not lower than the threshold, the battery supplies power to drive the air conditioner; if it is lower than the threshold, the air conditioner does not Start or tentative, detect the handbrake signal, after a period of time without the handbrake signal, charging is not allowed; if there is a handbrake signal, it enters the state of requesting advance charging. In the state of advance charging, when the charging power exceeds the threshold, the air conditioner is powered by the charging power supply. The invention considers the multi-objective coordinated control problem of the safety of people and vehicles, delayed charging and air-conditioning comfort in the process of charging with a gun, so that the charging process of the vehicle is safer, more in line with the user's wishes, and satisfies the user's experience. Especially suitable for electric coach vehicles.

Description

technical field [0001] The invention belongs to the operation control technology of electric vehicles, in particular to a control technology for charging electric vehicles and coordinating work of high-power electric appliances. Background technique [0002] With the popularization and use of electric vehicles, the scenarios where electric vehicles are applied are also increasing. Such as using the electric car as a coach car. The enabling requirements for electric vehicle training vehicles are generally relatively low, and the basic configuration includes fast charging and slow charging systems, delayed charging functions, air conditioning systems, no parking gears, and systems such as cable handbrake systems. When using, the handbrake is often not pulled up or the handbrake is not tightened. If it occurs during charging, the hazard will be further aggravated; in addition, when charging, there is usually a delayed charging request to achieve delayed charging. At the same t...
