example 1

[0058] Example 1: Wired mode.

[0059] Specifically, the charging pile sends a charging trigger signal to the on-board controller through a wired connection such as a wired Ethernet or an industrial serial bus (such as a CAN bus).

example 2

[0060] Example 2: Wireless mode.

[0061] Specifically, the charging pile sends a charging trigger signal to the on-board controller through wireless connections such as General Packet Radio Service (GRPS for short), Code Division Multiple Access (CDMA for short), and the like.

[0062] Step 102, receiving the working parameters corresponding to the vehicle battery fed back by the vehicle controller.

[0063] Step 103, acquiring charging parameters corresponding to working parameters according to preset charging information.

[0064] Specifically, different types of electric vehicles have different operating parameters for the vehicle batteries.

[0065] Among them, the working parameters can include one or more of the following: voltage working range, that is, the voltage of the car battery in a discharge state after being connected to a load; current working range, that is, the charging current and discharging current of the car need to be controlled within a certain range ...

Abstract

The invention proposes an automobile charging method, a charging pile and a vehicle-mounted controller. The method comprises the following steps of sending a charging trigger signal to the vehicle-mounted controller so that the vehicle-mounted controller detects an automobile battery according to the charging trigger signal; receiving a working parameter, corresponding to the automobile battery, fed back by the vehicle-mounted controller; acquiring a charging parameter corresponding to the working parameter according to preset charging information; and charging the automobile battery according to the charging parameter. Through the method according to the embodiment of the invention, automatic matching charging can be achieved according to battery characteristic, and the charging efficiency and the safety are improved.

Description

technical field [0001] The present application relates to the technical field of electric vehicle charging, in particular to a vehicle charging method, a charging pile and a vehicle-mounted controller. Background technique [0002] With the society's demand for energy saving and emission reduction, electric vehicles are getting more and more attention as a means of transportation that uses electric energy as clean energy. The charging stations for electric vehicles on the market are still in the initial stage, and it is impossible to realize that a charging pile can meet different types of vehicles. Charging requirements for electric vehicles. [0003] In related technologies, after manual input of battery parameters in the charging pile system, the charging pile can select different output voltages and currents to charge different models. [0004] However, the above method requires the driver to be familiar with the parameters of the battery. Inputting the wrong parameters...
