Embodiment 1

[0041] This embodiment 1 is applied to the charging pile, and the charging pile is provided with a control device and a charging device, combined with figure 1 As shown, the equalization control method of a charging module provided in Embodiment 1 includes:

[0042] Step S101: When receiving the charging request information, determine the charging power requirement of the electric vehicle;

[0043] Step S102: Obtain the startup priority and output power of multiple associated charging modules;

[0044] Step S103: Determine the working module among the multiple charging modules according to the charging power requirement, output power and starting priority;

[0045] Step S104: Control the work of the working module, and obtain the cumulative working hours sent by the working module under preset conditions, wherein the cumulative working hours are determined by the working module based on the historical working hours and the current working hours;

[0046] Step S105: When the ...

Embodiment 2

[0082] combine figure 2 As shown, Embodiment 2 provides a balance control device for a charging module, which is used to implement the balance control method in Embodiment 1. The control device includes:

[0083] The first determination unit 10 is configured to determine the charging power requirement of the electric vehicle when receiving the charging request information;

[0084] The first acquisition unit 20 is configured to acquire the start-up priority and output power of multiple associated charging modules;

[0085] The second determination unit 30 is configured to determine the working modules among the plurality of charging modules according to the charging power requirement, output power and starting priority;

[0086] The first control unit 40 is used to control the work of the working module, and obtain the cumulative working time sent by the working module under preset conditions, wherein the cumulative working time is determined by the working module based on t...

Embodiment 3

[0090] Embodiment 3 provides a charging pile, including a plurality of charging modules and an equalization control device for the charging modules in Embodiment 2. The charging modules are connected to the equalization control device, and the charging module has a built-in memory for storing its own accumulated working hours. The balance control device also has a built-in memory for storing the cumulative working hours of each charging module.

[0091] In the present invention, the charging pile dynamically adjusts the startup priority of the charging modules for subsequent charging according to the collected cumulative working hours of the internal charging modules according to its own balancing strategy, so that the working hours of each charging module are relatively balanced and the consistency of life is improved. Reduce maintenance frequency.

Abstract

In order to solve the technical problems of low utilization efficiency and unbalanced service life of a charging module in an existing charging pile, the invention provides a charging module equalization control method and control device, a charging pile and a storage medium. The equalization control method comprises the following steps: when charging request information is received, determining a charging power demand of the electric vehicle; acquiring starting priorities and output powers of a plurality of associated charging modules; determining a working module in the plurality of charging modules according to the charging power demand, the output power and the starting priority; controlling the working module to work, and obtaining the accumulated working duration sent by the working module under the preset condition, wherein the accumulated working duration is determined by the working module based on the historical working duration and the current working duration; and when the current charging process meets the charging stop condition, controlling the working module to stop working, and updating the starting priority of the plurality of charging modules according to the accumulated working duration of the working module. The starting priority is adjusted according to the accumulated working time.

Description

technical field [0001] The invention relates to the field of charging piles, in particular to an equalization control method of a charging module, a control device, a charging pile and a storage medium. Background technique [0002] With the popularity of electric vehicles, the charging pile market has also been well developed. For DC charging piles, the core component is the charging power module, hereinafter referred to as the charging module. The quality of the charging module and the length of its life directly affect whether the charging pile can operate normally in the market. At present, most manufacturers control the working mode of the charging module in a relatively simple way, such as starting all the charging modules at the same time to share the power for output, or using a fixed number and a fixed startup sequence to start the modules in sequence according to the requested power. to output. In the above two solutions, either the charging module cannot be used...
