Embodiment 1

[0056] combine figure 1 As shown, the battery charging method of the power station battery proposed by the present invention includes:

[0057] Step S101: Determine the current power supply period, the power supply period includes non-valley power period and valley power period;

[0058] Step S102: When the current power supply period is the off-peak power period, obtain the demand for battery replacement and the number of batteries that are currently fully charged at the battery replacement station;

[0059] Step S103: compare the demand for battery replacement and the number of fully charged batteries;

[0060] Step S104: If the demand for battery replacement is greater than the number of fully charged batteries, calculate the target number of batteries to be charged according to the demand for battery replacement and the number of fully charged batteries, and charge the target number of batteries that are not fully charged;

[0061] Step S105: If the demand for battery re...

Embodiment 2

[0074] In Embodiment 2, when the current power supply period is a non-valley power period, the demand for power exchange and the number of fully charged batteries at the power exchange station are obtained in real time; the demand for power exchange and the number of fully charged batteries are compared in real time. At any time during the off-peak power period, observe and analyze the relationship between demand and supply (the number of fully charged batteries in the swap station) in real time, and then adjust the supply to ensure that the demand for power swaps is met in a timely manner.

Embodiment 3

[0076] In Embodiment 3, at the first time point, the battery replacement demand within the first time period and the number of fully charged batteries at the first time point are obtained, wherein the first time point is a time point before the valley power period , the first time period is the time period between the first time point and the start time point of the valley electricity period. Guaranteed to meet the demand for battery replacement within the first time period. The first time point and the first time period can be set by the user and can be adjusted. For example, the first time period can be set to two hours, and the first time point is two hours earlier than the start time point of valley power.

[0077] In Embodiment 3, it is possible to obtain only the historical battery swapping amount in the first time period, and calculate an average value based on the data of multiple days. Specifically, taking one month as an example, the actual number of battery replace...

Abstract

In order to solve the technical problem of high electricity cost for electric vehicles, the present invention proposes a battery charging method and system in a power station. The battery charging method of the power exchange station of the present invention includes: determining the current power supply period, and the power supply period includes a non-valley power period and a valley power period; The number of batteries; compare the demand for battery replacement with the number of fully charged batteries; if the demand for battery replacement is greater than the number of fully charged batteries, calculate the target number of batteries to be charged according to the demand for battery replacement and the number of fully charged batteries, which is the target number Charge the partially charged batteries; if the demand for battery replacement is not greater than the number of fully charged batteries, suspend charging for all partially charged batteries. The present invention utilizes the valley electricity period to charge, reduces the cost of electricity consumption; through the long enough time and opportunity of the nighttime gap, the battery is maintained with a small current, prolonging the service life of the battery and maximizing the use of the value of the power battery.

Description

technical field [0001] The invention relates to the field of new energy vehicle charging, in particular to a method and system for charging a battery in a power station. Background technique [0002] Most of the electric vehicles in the current market are charged with the vehicle, and the charging method is mostly DC fast charging or AC slow charging. The charging time is relatively random, and the cost of use is uncontrollable; and the batteries of battery replacement electric vehicles occupying a small part of the market can be replaced and disassembled. , the charging form is concentrated charging in a fixed area, and its charging strategy is relatively single, and periodic charging is carried out according to a single rule, which cannot effectively utilize the valley power period, resulting in high electricity costs. [0003] Therefore, it is necessary to provide a solution to solve the technical problem of high electricity cost for electric vehicles. Contents of the i...
