Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example one
Referring to fig. 1, a method for controlling battery charging according to a first embodiment of the present invention is applied to a server, where the server is communicatively connected to an electric vehicle through a vehicle-mounted communication box of the electric vehicle, the electric vehicle includes a power battery and a battery connected to the power battery, the server may be implemented by software and/or hardware, and the method specifically includes steps S01 to S03.
And step S01, acquiring the current start-stop ratio of the storage battery, wherein the start-stop ratio is the ratio of the charging time length and the dormancy time length of the storage battery.
The start-stop ratio is a ratio of charging time length and dormancy time length of the storage battery, the dormancy refers to a state of the storage battery after the vehicle is powered off (namely, flameout and parking), and the storage battery needs to supply power to some electronic components (such as a vehicle-mounted communication BOX (T-BOX)) of the vehicle in the state and simultaneously requires to reserve electric quantity required by starting the vehicle.
By way of example and not limitation, in some cases of this embodiment, step S01 may specifically include:
acquiring the charging time of the last charging of the storage battery;
acquiring the current timing duration of a dormancy timer to obtain the current dormancy duration, wherein the dormancy timer starts timing after the electric vehicle is powered off;
and calculating to obtain the current start-stop ratio according to the current dormancy time length and the charging time length.
That is to say, the server is provided with a dormancy timer, when the electric vehicle is powered off, the vehicle-mounted communication box reports the power off information of the vehicle to the server, and at the moment, the server enables the dormancy timer to start timing, so that the current dormancy duration of the storage battery (namely the vehicle) can be mastered constantly, and the current start-stop ratio of the storage battery can be known constantly. The last charging time of the storage battery also needs to be reported to the server by the vehicle-mounted communication box.
And step S02, judging whether the current start-stop ratio is smaller than a start-stop ratio threshold value.
Specifically, the start-stop ratio threshold is data obtained by analyzing the server according to the capacity of the 12V storage battery and the whole power consumption of the automobile dormancy. For example, if the amount of electricity of the battery charged for 1 hour is approximately equal to the amount of electricity required for 8 days of sleep, that is, the battery charged for 1 hour can be used for 8 days of sleep, the start-stop ratio limit value is 1/8, and at this time, if the start-stop ratio limit value is set as the start-stop ratio threshold value, when the current start-stop ratio is equal to the start-stop ratio threshold value, if the vehicle is started right now, because the amount of electricity of the battery is nearly exhausted at this time, the vehicle still can be started or the vehicle still needs to be started by repeated ignition. Therefore, in particular implementations, to prevent the battery from being starved, the start-stop ratio threshold is typically set to a greater ratio limit, such as 1/6, to ensure that the battery still has sufficient charge to meet the vehicle start when the current start-stop ratio equals the start-stop ratio threshold.
When the current start-stop ratio is judged to be smaller than the start-stop ratio threshold value, the storage battery is in a power-shortage state, and step S03 is executed; and when the current start-stop ratio is judged to be not less than the start-stop ratio threshold, the storage battery is not in a power-shortage state, and the monitoring is not required to be continuously carried out.
And step S03, sending a charging instruction to the power battery through the vehicle-mounted communication box so that the power battery charges the storage battery.
It should be noted that, when the electric vehicle is in the Ready state or the ON electric state, the power battery may reversely charge the 12V storage battery, the Ready state is the vehicle driving state, and the ON electric state may not supply power to the driving motor, so that the vehicle may not drive. In particular implementations, therefore, the vehicle-mounted communication box may send an ON electrical command to the power battery to turn ON the power battery to charge the battery in step S03.
In summary, in the storage battery charging control method in the above embodiments of the present invention, the vehicle-mounted communication box is connected to the server, the server monitors the current start-stop ratio of the storage battery, and when the current start-stop ratio of the storage battery is lower than the set threshold, the vehicle-mounted communication box sends the charging instruction to the power battery, so that the power battery charges the storage battery, thereby better avoiding the occurrence of phenomena such as power shortage and power exhaustion of the storage battery after the vehicle is flamed out for a long time, and further better ensuring that the vehicle can still be normally started after flameout for a long time.
Example two
Referring to fig. 2, a battery charging control method according to a second embodiment of the present invention is applied to a server, where the server is communicatively connected to an electric vehicle through a vehicle-mounted communication box on the electric vehicle, the electric vehicle includes a power battery and a battery connected to the power battery, the server may be implemented by software and/or hardware, and the method specifically includes steps S11 to S15.
And step S11, acquiring the current start-stop ratio of the storage battery, wherein the start-stop ratio is the ratio of the charging time length and the dormancy time length of the storage battery.
And step S12, judging whether the current start-stop ratio is smaller than a start-stop ratio threshold value.
When the current start-stop ratio is judged to be smaller than the start-stop ratio threshold value, the storage battery is in a power-shortage state, and step S13 is executed; and when the current start-stop ratio is judged to be not less than the start-stop ratio threshold, the storage battery is not in a power-shortage state, and the monitoring is not required to be continuously carried out.
And step S13, judging whether the residual capacity of the power battery is larger than a capacity threshold value.
When the SOC of the residual electric quantity of the power battery is judged to be larger than the electric quantity threshold value, which represents that the electric quantity of the power battery is sufficient, the steps S14-S15 are executed; and when the SOC of the residual electric quantity of the power battery is judged to be not more than the electric quantity threshold value, representing that the electric quantity of the power battery is insufficient, not starting power supplement, and further ensuring the self residual electric quantity of the power battery.
And step S14, sending a charging instruction to the power battery through the vehicle-mounted communication box so that the power battery charges the storage battery.
And step S15, when the charging time of the storage battery reaches a charging time threshold value, sending a charging stopping instruction to the power battery through the vehicle-mounted communication box.
Generally, the capacity of a 12V storage battery mounted on an electric vehicle is generally fixed, and the 12V storage battery can be substantially fully charged when the power battery is charged for 1 hour, so that the charging time threshold can be set to 1 hour, that is, the power battery stops charging the storage battery after being started for 1 hour to charge the storage battery, and the waste of electric energy and the damage of the storage battery due to the overlong charging time are avoided.
Further, in some cases of the present embodiment, after the step of determining whether the remaining capacity of the power battery is greater than the capacity threshold, the method further includes:
and if not, pushing the electric vehicle power shortage prompt to a user terminal of the electric vehicle so as to prompt a user to supplement power for the vehicle as soon as possible.
Further, in some optional embodiments of the present invention, the method for controlling battery charging may further include:
periodically acquiring the total capacity and the dormancy power consumption of the storage battery;
and calculating to obtain a new start-stop ratio threshold according to the total capacity of the storage battery and the dormancy power consumption so as to update the start-stop ratio threshold regularly.
It should be noted that after the vehicle is equipped with the electronic device, the sleep power consumption of the storage battery is increased, so that the original charge for 1 hour can be used for 8-day sleep of the storage battery and is changed into only 7-day use of the storage battery, if the comparison and analysis are still performed according to the original start-stop ratio threshold value, the wrong judgment that the storage battery is actually insufficient, but the server still considers that the storage battery is not insufficient can occur, and in this case, the vehicle still cannot be started normally. Therefore, in the embodiment, the start-stop ratio threshold value is periodically updated by periodically acquiring the total capacity and the sleep power consumption of the storage battery, so that the phenomenon of the wrong judgment is better avoided.
By way of example and not limitation, in some cases of this embodiment, the step of calculating a new start-stop ratio threshold according to the total capacity of the storage battery and the hibernation power consumption includes:
calculating to obtain a start-stop ratio limit value according to the total capacity of the storage battery and the dormancy power consumption;
and increasing the limit value of the start-stop ratio by a preset buffer value to obtain the new threshold value of the start-stop ratio.
It can be understood that the number of days that the storage battery can maintain the sleep operation in the full-charge state can be calculated according to the total capacity of the storage battery and the sleep power consumption of each day, and the start-stop ratio limit value is 1/8 if the storage battery is fully charged for 1 hour and the sleep operation in the full-charge state can be maintained for 8 days. Since a certain buffer space is generally reserved in order to prevent the battery from being short of power, that is, the start-stop ratio threshold value is generally set to be larger than the start-stop ratio limit value, the start-stop ratio limit value is increased by the preset buffer value, so that a new start-stop ratio threshold value can be obtained, for example, the start-stop ratio is increased from 1/8 to 1/6.
