Specific embodiment
In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention also may be implemented in the other embodiments of details.In other situations, it omits to well-known system, system, electricity
The detailed description of road and method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Embodiment one:
As shown in Figure 1, present embodiments providing a kind of battery charge-discharge control method, specifically include:
Step S101: the charge and discharge time started of battery is obtained.
In a particular application, by introducing the concept of the times such as season, month, the morning, afternoon, evening, to determine battery
Management system enables battery management system adaptively to be adjusted according to temperature change in the temperature change of control charge and discharge process
Charge-discharge parameter is saved, realizes the charge and discharge control to battery.
In a particular application, it the charge and discharge time started for starting charge and discharge by obtaining battery in real time, is established by cable according to charge and discharge
Begin the temporal informations such as time determining locating at present season, month, period (morning, afternoon or evening).
In a particular application, battery management system real-time monitoring battery whether there is charging operations and discharge operation, work as electricity
Pond management system determines charge and discharge by reading the time of system clock when monitoring that battery starts to charge or starts electric discharge
Time started.
Step S102: variation of ambient temperature trend is obtained according to the charge and discharge time started.
In a particular application, it after being determined that battery starts the charge and discharge time started of charge and discharge, is established by cable according to the charge and discharge
Beginning, the time, to determine that the charge and discharge time started belongs to which, which and current time in season in month be the morning, the afternoon in one day
Or at night.It just can determine that out battery in charge and discharge according to the historical temperature data of Various Seasonal, different months, different periods
Variation of ambient temperature trend in journey.
In a particular application, due to Various Seasonal, different month, different periods temperature changing trend be it is different,
Such as the temperature change of the morning hours in spring is less than the temperature change of the morning hours of summer.Therefore, by obtaining different seasons
Section, a large amount of historical temperature data in different month and different periods determine each season, each according to historical temperature data
The temperature changing trend in month and each period.And by each season, each month, each period variation tendency with it is corresponding
Time be associated storage.
In a particular application, since the duration of battery charge or discharge can be estimated according to the remaining capacity of battery,
Therefore the period needed for can determine charge or discharge, determine battery in charge and discharge by the beginning charge and discharge time of battery
Temperature changing trend in length determines charge or discharge operation locating season, month and the period by the charge and discharge time started,
And then corresponding temperature changing trend is obtained from the database for storing time and temperature changing trend.
It is exemplary, if the beginning charge and discharge time is morning 8:00 on January 12, searched on January in spring-- from database
The corresponding temperature changing trend of noon 8:00.

Environment temperature rises, and then avoids the charge power of battery pack beyond security boundary.
In a particular application, when battery pack during discharge can by the road horsepower of current vehicle, locating season,
Time in locating one day reasonably optimizes discharge power curve, so that it is too fast effectively to avoid the temperature of battery pack from increasing, surpasses
Out the case where the security boundary of battery pack.
Illustratively, when the noon traveling under burning sun, it can suitably reduce power output, avoid temperature overshot in advance, keep away
It is excessive to exempt from power releasing, battery pack temperature is caused to increase too fast, the security boundary beyond battery pack.When at night or morning row
It is appropriate to decontrol power output dynamics the characteristics of reduction according to this period constant temperature if sailing, to maintain the temperature of battery
It is too fast that degree is unlikely to battery temperature decline.
In a particular application, charge power is reduced again after temperature variation curve ascensional range is larger, due to battery pack
The limitation of heat radiation power, battery pack temperature can also hysteresis quality raising, battery pack operational safety boundary will be exceeded, and can not be fast
Fast effectively control.
