How to improve the safety of the storage battery during charging will be described in detail below with reference to the specific embodiments and the accompanying drawings.
Example one
Referring to fig. 2, a method for charging a battery according to a first embodiment of the present invention is applied to a communication module of a vehicle, and the method includes steps S10 to S14.
And step S10, controlling a storage battery sensor to monitor the battery capacity of a storage battery of the vehicle in real time in the flameout process of the vehicle.
The battery sensor calculates the battery capacity of the storage battery by monitoring the voltage, the current and the temperature of the storage battery, the battery capacity signal provided by monitoring the voltage, the current and the temperature of the storage battery is more accurate and intelligent, and the problem that the read capacity value is inconsistent with the actual capacity value of the storage battery due to the fact that the capacity value is directly read by a battery management system under the conditions of aging of the storage battery and the change of the ambient temperature is solved.
And step S11, when the battery electric quantity of the storage battery is lower than a first preset electric quantity threshold value, sending a charging request to a user.
Further, when it is detected that the battery power of the storage battery is lower than the first preset power threshold, a charging request is sent to the user, and it can be understood that, when it is detected that the battery power of the storage battery is lower than the first preset power threshold, that is, the storage battery needs to be charged at this time to prevent the storage battery from being fed after being left at rest for a long time, specifically, the first preset power threshold may be set to 20%, 30% or 40%, and a selection may be made according to an actual situation, and the charging request is sent to the user to remind the user that the storage battery is being fed, so as to prompt the user that the storage battery needs to be charged.
Specifically, in some optional embodiments of the present invention, the charging request is sent to the car networking platform, the car networking platform forwards the charging request to the user, and the user can receive the charging request forwarded by the car networking platform through the mobile app and issue an instruction through the operation of the mobile app to determine whether to charge the storage battery.
And step S12, when receiving a charging command which is a command issued by the user according to the charging request, acquiring the voltage state of the power battery pack.
In order to further increase the safety of the storage battery during charging, when an instruction issued by a user according to a charging request is received as a charging instruction, the storage battery needs to be charged at this time to prevent feeding, and the voltage state of the power battery pack is obtained to determine whether the voltage state of the power battery pack is suitable for charging the storage battery.
More specifically, after receiving a charging request pushed by a mobile phone APP, a user sends a command by operating the APP on the mobile phone, where the command includes a "charging command" and a "no-charging command", and when receiving a charging command issued by the user according to the charging request, the power battery pack is controlled to charge the storage battery, for example and without limitation, in this embodiment, when the mobile phone APP receives the charging request sent by the car networking platform, the mobile phone APP displays a charging interface, where the charging interface includes "charging" and "no-charging" areas, the user can send the charging command or no-charging command by clicking the area corresponding to "charging" and "no-charging", control the power battery pack to charge the storage battery by issuing the "charging command", and issue the "no-charging command", that is, the storage battery does not need to be charged, for example, in actual life, under certain specific circumstances, when the storage battery is lower than the first preset electric quantity threshold value, when a user receives a charging request, a 'non-charging instruction' needs to be issued to not charge the storage battery, wherein specific situations include but are not limited to that the user needs to drive a vehicle in a period close to the period when the charging request is received or the vehicle is parked to a charging unsuitable period (such as a high magnetic field area or a high dust area).
Step S13, determining whether the voltage state satisfies a preset charging condition; if yes, go to step S14.
Specifically, when the battery is charged, certain requirements are imposed on the voltage value and the stability of the voltage, for example, when the voltage value of the power battery pack is too high or the voltage value of the power battery pack is unstable, the storage battery can be damaged by directly charging the storage battery, therefore, by judging whether the voltage state meets the charging state of the storage battery, therefore, the safety of the storage battery during charging is improved, and it can be understood that the voltage state comprises the current voltage value of the power battery pack and the floating range of the voltage value of the power battery pack within a period of time, the preset charging condition is the voltage value suitable for charging the storage battery corresponding to the preset charging condition and the floating range of the voltage value suitable for charging the storage battery within a period of time, specifically, the storage battery can be charged within a certain range by setting the voltage value, or the magnitude of the change in the voltage value over a period of time is within a predetermined range.
And step S14, controlling the power battery pack to charge the storage battery.
Specifically, when the voltage state meets the preset charging state, it is indicated that the power battery pack is in a state capable of charging the storage battery, that is, the power battery pack is controlled to charge the storage battery.
In summary, in the storage battery charging method in the above embodiments of the present invention, the storage battery sensor is used to monitor the battery power of the storage battery in real time, and when the battery power is lower than the first preset power threshold, a charging request is sent to a user, and the user can feed back a charging instruction according to the charging request and obtain the voltage state of the power battery pack, so as to determine whether the power battery pack can currently charge the storage battery, thereby avoiding charging the storage battery when the power battery pack is not suitable for charging, and solving the problem of low safety of the storage battery during charging in the prior art.
Example two
Referring to fig. 3, a method for charging a battery according to a second embodiment of the present invention is applied to a communication module of a vehicle, and the method includes steps S20 to S27.
And step S20, controlling a storage battery sensor to monitor the battery capacity of a storage battery of the vehicle in real time in the flameout process of the vehicle.
And step S21, when the battery electric quantity of the storage battery is lower than a first preset electric quantity threshold value, sending a charging request to a user.
And step S22, when receiving a charging command which is a command issued by the user according to the charging request, acquiring the voltage state of the power battery pack.
Specifically, in an actual situation, there may be a situation that the user cannot accept the charging request or is difficult to issue an instruction in time, for example, the user is in a meeting or bathing and cannot acquire information pushed by the mobile phone APP in time, or communication between the mobile phone of the user and the internet of vehicles is damaged, based on this, in some optional embodiments of the present invention, when an instruction issued by the user according to the charging request is not accepted within a preset time, the voltage state of the power battery pack is directly acquired, and more specifically, the preset time may be set to 30min, 60min, and 75min and may be set according to the actual situation.
Step S23, determining whether the voltage state satisfies a preset charging condition, if not, performing step S24, and if so, performing step S25.
And step S24, controlling the power battery pack to charge the storage battery through a second charging circuit, wherein a voltage stabilizing module is arranged on the second charging circuit and used for stabilizing the voltage of the power battery pack.
And step S25, controlling the power battery pack to charge the storage battery through a first charging circuit.
Specifically, two charging circuits, namely a first charging circuit and a second charging circuit, are arranged between the power battery pack and the storage battery, the first charging circuit and the second charging circuit are connected through a circuit change-over switch, and only one of the first charging circuit and the second charging circuit can be conducted through the circuit change-over switch; the second charging circuit is provided with a voltage stabilizing module, the power battery pack is connected with the DCDC module through the voltage stabilizing module, the voltage stabilizing module on the second charging circuit can stabilize unstable voltage output by the power battery pack, and when the voltage state meets the preset charging condition, the power battery pack is controlled to charge the storage battery through the first charging circuit; and when the voltage state does not meet the preset charging condition, controlling the power battery pack to charge the storage battery through the second charging circuit.
When the voltage state does not satisfy the preset charging condition, the storage battery needs to be charged through the second charging circuit, however, since the voltage stabilizing module also belongs to a power consuming element, the power consumption of the storage battery can be consumed when the voltage stabilizing module is frequently used for charging, and in practice, the voltage stabilizing effect of the voltage stabilizing module is not satisfactory, even if the voltage is stabilized through the voltage stabilizing module, the output voltage sometimes appears unstable, and a certain damage can be caused to the storage battery, most importantly, the voltage output by the power battery pack is stabilized through the voltage stabilizing module, only the voltage received by the storage battery can satisfy the preset charging condition, but the power battery pack still has the unstable voltage condition, therefore, when the voltage state does not satisfy the preset charging condition, the voltage state of the power battery pack is repaired in a preset mode, the voltage state of the power battery pack is fundamentally stabilized, wherein the preset mode is any one of restarting the power battery pack and waiting for self-repairing of the power battery pack.
As can be understood, there are many factors that cause the voltage state of the power battery pack to be unstable, for example, sudden instability at a certain time or external environmental factors affect the instability of the voltage state of the power battery pack at a certain moment or a certain time period, so that the voltage state of the power battery pack can be repaired by restarting the power battery pack or self-repairing the power battery pack.
Based on this, in some alternative embodiments of the invention:
when the voltage state does not meet the preset charging condition, the voltage state of the power battery pack is repaired according to a preset mode;
in the process of repairing the voltage state of the power battery pack, judging whether the battery electric quantity of the storage battery is lower than a second preset electric quantity threshold value, wherein the second preset electric quantity threshold value is lower than the first preset electric quantity threshold value;
if not, the voltage state of the power battery pack is restored to meet the preset charging condition, and the power battery pack is controlled to charge the storage battery through the first charging circuit;
