Reserved charging method, system and computer-readable storage medium

Abstract

A scheduled charging method, scheduled charging system, and computer-readable storage medium, the method comprising: executing the scheduled charging function; analyzing the fully charged capacity of a battery pack, judging whether the battery pack can be fully charged, and analyzing the fully charged capacity of the battery pack The steps include calculating the heat balance temperature that the battery pack can maintain when the charging system is charging according to the current maximum allowable charging power, and judging the heat balance temperature that the battery pack can maintain when charging according to the current maximum allowable charging power and the minimum temperature at which the battery pack can be fully charged. The relationship between temperature, according to the judgment result, it is determined that charging needs to be started immediately or at least one of the strategy analysis of the lowest charging cost, the strategy analysis of the least energy consumption during the charging process, and the optimal state of the battery pack are carried out; When it can be fully charged, at least one of the strategy analysis for realizing the lowest charging cost, the strategy for realizing the least energy consumption during charging, and the strategy for realizing the best state of the battery pack is carried out.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a scheduled charging method, a scheduled charging system and a computer-readable storage medium. Background technique [0002] For the reserved charging function of new energy vehicles, since the charging start time and charging time are mostly set by the user according to the subjective wishes, there may be inaccurate estimates of the full charging time, resulting in the situation that the car is still not fully charged when it is time to use the car. Or the peak and valley power policy is not fully considered when setting the charging time, resulting in high cost and poor economy even though the battery is fully charged. Moreover, the existing scheduled charging function usually uses the maximum capacity of the system after the scheduled charging time is completed. Charging will cause a large amount of heat generated during the charging process, and at the same time, the cooling system...

[0002] For the reserved charging function of new energy vehicles, since the charging start time and charging time are mostly set by the user according to the subjective wishes, there may be inaccurate estimates of the full charging time, resulting in the situation that the car is still not fully charged when it is time to use the car. Or the peak and valley power policy is not fully considered when setting the charging time, resulting in high cost and poor economy even though the battery is fully charged. Moreover, the existing scheduled charging function usually uses the maximum capacity of the system after the scheduled charging time is completed. Charging, resulting in a large amount of heat during the charging process, and at the same time need to start the cooling system to cool the battery pack, resulting in more energy loss during the charging process

[0003] In addition, because the charging and discharging performance of the battery pack is greatly affected by temperature, in a low temperature environment, after the charging start time is reached, the battery may not be fully charged due to the low temperature of the battery and poor charging and discharging performance, or it may need to be heated by a third party.
