Referring to fig. 1, a system block diagram of a charging control method according to the present invention is shown. The charging Control method provided by the invention is applied to a controller, and the controller can be, for example, a Vehicle Control Unit (VCU), can also be, for example, a Body Control Module (BCM), and can also be, for example, another controller different from the Vehicle Control unit and the Body controller. Next, the controller will be described as an example of a vehicle controller. In fig. 1, a BCM and a Direct-Direct Current (DC-DC) converter are connected to a battery through a Local Interconnect Network (LIN), respectively. An Intelligent Battery Sensor (IBS) is connected between the BCM and the Battery. The Battery Management System (BMS), the BCM, the Ignition Control Module (ICM), and the DC-DC are connected to the VCU through a Controller Area Network (CAN), respectively.
Referring to fig. 2, a schematic flow chart of a charging control method according to an embodiment of the present invention includes the following steps:
s201: and when the vehicle is in a dormant state, acquiring the residual electric quantity value of the storage battery according to a preset time interval.
When the vehicle is in a dormant state, the power supply of the vehicle is in a closed state, all doors of the vehicle are in a locked state, and a back door and a front engine room cover of the vehicle are in a closed state.
When the vehicle is in a dormant state, the vehicle body controller CAN acquire the residual electric quantity value of the storage battery through the intelligent battery sensor and send the residual electric quantity value of the storage battery to the vehicle control unit through the CAN bus, so that the vehicle control unit CAN acquire the residual electric quantity value of the storage battery. In order to reduce the consumption of the battery capacity of the vehicle controller and the vehicle body controller when the vehicle is in the sleep state, the vehicle controller may obtain the remaining capacity of the battery at preset time intervals, for example, the time intervals may be 1 hour or 3.5 hours or 5 hours.
S202: and if the residual electric quantity value of the storage battery is smaller than a first preset electric quantity value and the vehicle state meets the dormant charging condition, awakening the gateway and controlling the direct current-direct current converter DC-DC to charge the storage battery.
The remaining electric quantity value of the battery may be a percentage value, and the first preset electric quantity value may be 20% or 27% or 35%, for example. When the residual electric quantity value of the storage battery is smaller than the first preset electric quantity value, the residual electric quantity value of the storage battery is lower, and the electric quantity needs to be supplemented. When the vehicle meets the dormant charging condition, the DC-DC can be controlled to charge the storage battery by waking up the gateway. Therefore, when the residual electric quantity of the storage battery is low, the storage battery can be supplemented with electric quantity in time, the storage battery is prevented from being damaged due to insufficient electricity, and the service life of the storage battery can be prolonged. And, through preventing the electric shortage of storage battery, can guarantee the normal start and use of vehicle, improve the performance of vehicle and user's satisfaction.
Alternatively, the first preset electric quantity value may be, for example, 80% or 85%, in which case, when the remaining electric quantity value of the storage battery is lower than the first preset electric quantity value, the DC-DC is controlled to charge the storage battery, so that the remaining electric quantity value of the storage battery can be kept in a higher state in a shorter time. Therefore, the maintenance function of the storage battery can be realized, the storage battery is prevented from being vulcanized too fast, the health state of the storage battery is ensured, and the service life of the storage battery is prolonged. Also, the vehicle-leaving time of the vehicle in the sleep state can be extended.
For example, the sleep charging condition includes:
(1) a fault signal of the vehicle is not acquired;
(2) the residual electric quantity value of the power battery is larger than or equal to a second preset electric quantity value.
In the condition (1), the fault signal of the vehicle may include, for example, a vehicle low-voltage fault, a DC-DC operation fault, and a vehicle high-voltage interlock fault. And if the vehicle control unit does not acquire the fault signal of the vehicle, the vehicle is normal.
In the condition (2), the vehicle control unit controls the DC-DC to charge the battery, and actually converts the high voltage of the power battery into the low voltage of the battery. When the residual electric quantity value of the power battery is greater than or equal to a second preset electric quantity value, wherein the second preset electric quantity value can be 20% or 23% or 27%, for example, the DC-DC is controlled to charge the storage battery, so that the situation that the power battery is lack of electricity is caused in the process of converting the electric quantity of the power battery into the electric quantity of the storage battery can be avoided. If the power battery is insufficient, the vehicle may not run or may not run enough to the charging station after being powered on, and the use experience of the user is reduced.
By determining that the vehicle meets the dormant charging condition, the safety of the vehicle controller in the process of controlling the DC-DC to charge the storage battery (the charging process can not be stopped due to vehicle faults) can be improved, the power shortage of the power battery caused after the power battery charges the storage battery can be avoided, and the reliability of charging the storage battery is improved.
In an example, after controlling the DC-DC converter DC-DC to charge the battery, the method further includes:
and when the vehicle is judged to meet the charging stop condition, controlling the DC-DC to stop charging the storage battery.
Wherein the charge stop condition includes at least one of:
1) the residual electric quantity value of the storage battery is greater than or equal to a third preset electric quantity value, wherein the third preset electric quantity value is greater than or equal to the first preset electric quantity value;
2) the charging time of the DC-DC to the storage battery is longer than or equal to a preset charging time;
3) the residual electric quantity value of the power battery is smaller than a second preset electric quantity value;
4) acquiring a charging signal for charging a vehicle by a charging gun;
5) acquiring a fault signal of a vehicle;
6) and acquiring a starting signal of the vehicle.
In the condition 1), the third preset electric quantity value may be, for example, 90% or 95% or 100%, and generally, the third preset electric quantity value is greater than or equal to the first preset electric quantity value, so that the electric quantity of the storage battery can be ensured to be replenished. If the residual electric quantity value of the storage battery is greater than or equal to the third preset electric quantity value, the residual electric quantity value of the storage battery is higher, and the storage battery does not need to be charged. At this time, by controlling the DC-DC to stop charging the battery, overcharge of the battery can be avoided.
In the condition 2), generally, the remaining electric quantity value of the secondary battery may reach the third remaining electric quantity value before the charging period reaches the preset charging period, which may be, for example, 2 hours or 2.5 hours or 3 hours. If the charging time of the storage battery by the DC-DC is longer than or equal to the preset charging time, the charging process may be abnormal, and at the moment, the danger in the charging process can be avoided by controlling the DC-DC to stop charging the storage battery. Moreover, the situation that the power battery is always charged to the storage battery, so that the power battery is lack of power can be avoided.
In the condition 3), if the residual electric quantity value of the power battery is smaller than the second preset electric quantity value, it indicates that the residual electric quantity of the power battery is low. At this time, by controlling the DC-DC to stop charging the storage battery, it is possible to avoid the power shortage of the power battery.
In condition 4), the charging gun charges the vehicle, and actually the charging gun charges the power battery. When the charging gun charges the power battery, it needs to be ensured that the power battery is not in a working state. Therefore, the vehicle control unit feeds back a charging stop request to the battery management system to control the power battery to stop charging. And the vehicle control unit controls the DC-DC to stop charging the storage battery, so that the safety of the charging gun in the vehicle charging process can be ensured. If the DC-DC still charges the battery during the charging process of the charging gun to the vehicle, the temperature of the power battery is likely to rise, and if the temperature is severe, the vehicle may be caused to self-ignite. After controlling the DC-DC to stop charging the battery, the vehicle enters a charging mode.
In condition 5), when the vehicle fails, the charging process of the DC-DC to the storage battery cannot be stopped, the storage battery is overcharged, and even a safety accident is caused. In this case, by controlling the DC-DC to stop charging the battery, the above-described situation can be avoided.
In condition 6), the start signal of the vehicle may include, for example, an opening signal of a door, an opening signal of a front hood, and an opening signal of a trunk door. When the starting signal of the vehicle is acquired, the vehicle using requirement of the user or the requirement of the user for detecting the vehicle can be determined. At this time, the charging of the storage battery is stopped by controlling the DC-DC, so that the normal use of the vehicle and the detection of the vehicle by a user can be satisfied.
For example, the charge control method further includes: and outputting fault prompt information when the fault signal of the vehicle is acquired.
The vehicle control unit can send fault information to an instrument panel, and a user can know that a vehicle has a fault through characters or icons on the instrument panel and timely overhaul the vehicle. Optionally, the vehicle control unit may also send the fault information to a mobile device of the user, such as a mobile phone or a tablet computer, so that the user may know that the vehicle has a fault.
In an example, the charge control method further includes: and before the fault signal is cleared and/or in a preset period, when the charging frequency of the storage battery by the DC-DC is greater than or equal to the preset charging frequency, the DC-DC is not controlled to charge the storage battery.
If the DC-DC is controlled to charge the battery before the fault signal is cleared, a danger may occur during the charging process. By not controlling the DC-DC to charge the battery, the above-described situation can be avoided. In a preset period, for example, the preset period may be 5 days, 15 days or 30 days, and the number of times of charging the DC-DC to the storage battery is greater than or equal to a preset number of times of charging, for example, the preset number of times of charging is 2 times, 3 times or 4 times, which indicates that the vehicle may be in a sleep state all the time or that the health of the storage battery is degraded. In this case, if the DC-DC is still controlled to charge the storage battery, the remaining power of the power battery may be reduced, even the power battery may be insufficient, and finally the vehicle cannot run due to the power battery being insufficient after being powered on, which may reduce the user experience. By not controlling the DC-DC to charge the battery, the above can be avoided.
Next, referring to fig. 3, a flow of the charging control method will be further described. For convenience of description, the "controlling the DC-DC to charge the storage battery" is referred to as intelligent power supplement, and the "the residual electric quantity value of the storage battery is smaller than a first preset electric quantity value and the vehicle state meets the dormant charging condition" is referred to as intelligent power supplement condition.

S306: and if the intelligent power supply stopping condition is not met, continuing to perform intelligent power supply.
S307: and if the intelligent power supply condition is not met, returning to the step S302.
It should be noted that, in the intelligent power supply process, the vehicle software is prohibited from updating. And if the vehicle software is updated in the intelligent power supplementing process, the intelligent power supplementing process is stopped.
