Embodiment Construction

[0019] The specific implementations of the charging method and the charging device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] attached figure 1 Shown is a schematic diagram of the implementation steps of this specific embodiment, including: step S10, a power supply device establishes a communication connection and a charging connection with a power demand device through a charging plug; step S11, the power supply device obtains the A power demand identification code; step S12, the power supply device compares the power demand identification code with other power demand identification codes that have been obtained, and if there is no difference, then turn on the single gun charging mode, and if there is the same, turn on the double gun Charging mode; step S13, the power supply device sends a power supply identification code to the power demand device, and the power supply identification code is use...

Abstract

The invention provides a charging method. The charging method comprises the following steps: a power supply device establishes communication connection and charging connection with a power requiring device through a charging plug; the power supply device acquires a power requiring identification code sent by the power requiring device; the power supply device compares the power requiring identification code with other acquired power requiring identification code; if the power requiring identification code is different from other acquired power requiring identification code, a single-gun charging mode is started; if the power requiring identification code is same as other acquired power requiring identification code, a dual-gun charging mode is started; the power supply device sends one power supply identification code to the power requiring device, and the power supply identification code is used for judging whether the current charging plug is the master plug or a slave plug by the power requiring device.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a charging method and a charging device. Background technique [0002] With the increase of environmental pollution and the impact of the energy crisis, the development of new energy vehicles has received more and more attention, among which pure electric vehicles have increasingly become the mainstream direction of market development. Because of the faster charging speed, users tend to use high-power charger products when using chargers. [0003] The DC charging methods of commercial vehicles are mainly divided into two methods: single gun charging and double gun charging. Single gun charging is limited by the current limit, making it difficult to increase the charging speed. The double gun charging can provide double the charging current and double the charging speed, so it can meet the requirements of fast charging of vehicles and is favored by more and more customers. [0004] Wh...
