Description

Technical Field

At present, the new energy automobile develops rapidly, and the storage battery is used as a standby power supply for the operation of the new energy automobile, so that the performance of the storage battery influences whether the automobile can work normally. Batteries for electric vehicles include high-voltage power storage batteries (providing power for motors, vehicle heaters (PTC), etc., abbreviated as "large batteries") and low-voltage 12V storage batteries (providing power for meters, controllers, etc., abbreviated as "small batteries"). When the vehicle is not started after long-time standing, the feeding phenomenon of the 12V storage battery is easy to occur, and the whole vehicle controller cannot wake up, so that high voltage cannot be generated, and the vehicle cannot be started.

In the related art, in order to solve the feeding problem of the 12V storage battery, basically, when the condition that the low-voltage storage battery needs to be charged is detected, a whole vehicle controller is awakened through a series of hardware modules, and the whole vehicle controller carries out high-voltage on the basis of an upper high-voltage condition. If a certain high voltage condition is not met, the high voltage is not met, and the storage battery cannot be charged.

However, the problem of the related technology is that the whole vehicle controller may continuously sleep and wake up when the low-voltage storage battery needs to be charged but the high voltage is not detected, and the main positive relay and the main negative relay may be continuously closed and disconnected, so that the probability of damage to the main positive relay and the main negative relay is increased and the failure rate of a hardware board of the whole vehicle controller is increased. Under the condition that high voltage is not available, the whole vehicle controller is not in a dormant state after being awakened, so that the electric quantity of the low-voltage storage battery is lower, and all modules are dormant to stop working, and therefore follow-up intelligent power supply cannot be realized.

Accordingly, it is intended that the present application covers the modifications and variations of this application provided they come within the scope of the appended claims (the claims) and their equivalents. The embodiments provided by the embodiments of the present application may be combined with each other without contradiction.

Before describing the technical solution provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application firstly specifically describes the problems existing in the related art:

At present, the new energy automobile develops rapidly, and the storage battery is used as a standby power supply for the operation of the new energy automobile, so that the performance of the storage battery influences whether the automobile can work normally. The battery of the electric automobile comprises a high-voltage power storage battery pack (for providing power for a motor, PTC and the like, hereinafter referred to as a large battery) and a low-voltage 12V storage battery (for providing power for an instrument, a controller and the like, hereinafter referred to as a small battery), when the automobile is not started for a long time, the phenomenon of feeding the 12V storage battery is easy to occur, the whole automobile controller cannot be awakened, the high voltage is further avoided, the automobile cannot be started, complaints of users are caused, and the use and the brand image of the automobile are influenced.

In general electric automobile design, low-voltage storage battery only charges whole car 12V battery through DCDC after the vehicle starts, provides continuous power to whole car low pressure power consumption system simultaneously, but can't realize the function of accomplishing the initiative moisturizing to 12V power during the vehicle is still put. And the other is a design (generally called intelligent power supply) for carrying out power supply by detecting the voltage condition of the storage battery, so that the power supply condition of the storage battery is reduced to a certain extent.

Fig. 1 is a schematic structural diagram of a power supply device according to the related art. As shown in fig. 1, the wake-up module 102 wakes up by KL15 (key) or a+ (charge) or the like under normal conditions, and then completes the high-voltage power-on flow. In the related art, basically, the low-voltage battery detection module EBS 'performs real-time voltage detection on the battery, and when the battery is in a power-up condition, the EBS' can inform the vehicle control module BCM 'through wireless communication (including Lin communication), the BCM' wakes up the whole vehicle controller VCU 'through a hard wire L2, and then the VCU' performs high-voltage operation according to the high-voltage condition, so as to perform power-up on the battery. Some schemes combine with the command module TBOX' to determine whether to power up at high voltage.

If the storage battery needs to be charged, the BCM ' wakes up the VCU ' through the L2, the VCU ' carries out high voltage according to the high voltage condition, and if a certain high voltage condition is not met, the high voltage is not applied, and the storage battery cannot be charged.

There are two cases at this time:

First, this wake-up procedure, because high voltage is not applied, the BCM ' stops waking up the VCU ' through the L2, but the VCU ' sleeps for a certain period of time, although high voltage is not applied. The latter EBS 'will wake up the VCU' again from the L2. If the upper high pressure condition is not met, the process is repeated. Therefore, the VCU 'is continuously and repeatedly dormant and wakes up, and the main positive relay and the main negative relay can be continuously and repeatedly sucked and disconnected, so that the probability of damage of the main positive relay and the main negative relay is increased, and the failure rate of a hardware board of the VCU' is increased.

The second is, this time wake up the power supply process, BCM ' can be continuous to wake up VCU ' through L2, although not having high voltage, but VCU ' also can not sleep, after a period of time like this, the battery electric quantity can be lower because by several controllers, and then lead to the controller of all modules (including ordinary electric module and VCU ' etc.) to stop working because of the electric quantity is low, and follow-up start can't, can only take the electricity to the battery through external power source, make the whole car carry out the power supply to the battery after high voltage. Thus, as with vehicles without intelligent power-up function, the vehicle is not started, causing customer complaints and brand image.

In order to solve the technical problems, the application provides a power supplementing device, a power supplementing method and electric equipment, and the core of the power supplementing device is that a protection device and a protection method on hardware and software are added on the basis of a normal power supplementing function, so that frequent wake-up start of a whole vehicle controller caused by sensor faults or other faults of the whole vehicle is avoided. In the power-down state, if the whole vehicle is frequently awakened and started, the probability of damaging parts such as a high-voltage relay is increased, the electricity of a storage battery is wasted, and the application can avoid the problems. The following first describes the power supply device of the present application.

Fig. 2 is a schematic structural diagram of a power supply device according to an embodiment of the present application, and as shown in fig. 2, the power supply device 200 may include: the system comprises a detection control module 210, a switch module 220 and a vehicle controller VCU.

The embodiment of the present application further provides an electric device, where the electric device 300 may include: a battery 201 and a recharging device 200.

The battery 201 is electrically connected to the power supplementing device 200, and the power supplementing device 200 is configured to supplement power to the battery 201 when the voltage state of the battery satisfies a preset power supplementing condition.

In some embodiments, the detection control module 210 is electrically connected to the battery 201, and is configured to detect a voltage of the battery 201, and send a wake-up signal and a power-up request when the voltage of the battery 201 meets a preset power-up condition.

In some embodiments, the preset power up condition may be that the detected voltage of the battery 201 is below X volts for more than Y seconds.

A first end of the switch module 220 is electrically connected to the detection control module 210. The switch module 220 is controlled by the vehicle control unit VCU.

The vehicle controller VCU is electrically connected to the second end of the switch module 220, and the vehicle controller VCU is configured to switch from the sleep state to the wake state in response to the wake signal when the switch module 220 is turned on, and to supplement power to the battery 201 in response to the power-up request when the vehicle meets the high-voltage power-up condition in the wake state.

The whole vehicle controller VCU is also used for acquiring the number of times of power-on fault when the vehicle does not accord with the high-voltage condition; when the number of the power-up faults is greater than or equal to a first preset threshold, the control switch module 220 is turned off; and enters a sleep state after the switch module 220 is turned off.

In the power supplementing device of the embodiment of the application, when the whole vehicle controller VCU does not meet the high-voltage power-on condition, the detection control module 210 always sends the power supplementing request, and as the whole vehicle controller VCU can acquire the power supplementing fault times, when the power supplementing fault times are greater than or equal to the first preset threshold value, the control switch module is disconnected, so that the wake-up signal and the power supplementing request sent by the detection control module 210 cannot reach the whole vehicle controller VCU and wake up after meeting certain times, and the situation that the whole vehicle controller VCU is repeatedly waken and always not dormant by the detection control module 210 when the whole vehicle controller VCU has the high-voltage power-on condition is avoided, thereby achieving the effect of avoiding device loss and not influencing the successful power supplementing condition when the whole vehicle controller VCU meets the high-voltage power-on condition.

Fig. 3 is another schematic structural diagram of a power supply device according to an embodiment of the present application, as shown in fig. 3, in some embodiments, the power supply device 200 further includes a lower electrical storage chip EEPROM, the lower electrical storage chip EEPROM is electrically connected to the vehicle controller VCU, and the lower electrical storage chip EEPROM is configured to add one to a value of a number of power supply failures when the vehicle controller VCU receives a power supply request once and does not supply power to the battery 201; the whole vehicle controller VCU is used for calling the number of power-on fault times from the lower electric storage chip EEPROM.

In some embodiments, the lower electrical memory chip EEPROM is integrated inside the vehicle controller VCU. Fig. 3 shows an example in which the electrical memory chip EEPROM is integrated inside the vehicle controller VCU, and the switch module 220 shows the relay K1.

With continued reference to fig. 3, in some embodiments, the detection control module 210 may include: a battery detection unit EBS and a vehicle control unit BCM.

The battery detection unit EBS is electrically connected to the battery 201, and is configured to detect a voltage of the battery 201, and send a power replenishment request when a duration of time that the voltage of the battery 201 is lower than the second preset threshold exceeds a third preset threshold. The voltage of the battery 201 should be the real-time voltage of the battery 201. For example, the battery detection unit EBS may be configured to issue a power replenishment request when detecting that the real-time voltage of the battery 201 is lower than 10V for 3S.

The vehicle control unit BCM is in communication connection with the storage battery detection unit EBS, and is used for responding to the power supplementing request and sending a wake-up signal and the power supplementing request to the whole vehicle controller VCU.

In some embodiments, the vehicle controller VCU is further configured to detect whether the voltage of the battery 201 reaches a full condition when the voltage of the battery 201 is full, perform power-up on the battery 201 when the voltage of the battery 201 is detected to not reach the full condition, and enter the sleep state when the voltage of the battery 201 is detected to reach the full condition.

In some embodiments, the lower electrical storage chip EEPROM is further configured to clear the number of power-up faults when the vehicle controller VCU detects that the voltage of the battery 201 reaches the full condition. The whole vehicle controller VCU is also used for controlling the switch module to be opened and enter a dormant state under the condition of resetting the times of the power-on fault.

With continued reference to fig. 3, the power replenishment device 200 may further include: a wake module 301 and a command module TBOX.

The wake-up module 301 is electrically connected with the vehicle controller VCU, and the wake-up module 301 is configured to switch the vehicle controller VCU from a sleep state to a wake-up state when a start of the vehicle or a charge of the vehicle is detected; the command module TBOX is used for waking up the whole vehicle controller VCU and sending a power supply request to the whole vehicle controller VCU; the lower electric storage chip EEPROM is also used for resetting the number of times of power-on fault when the wake-up module 301 wakes up the whole vehicle controller VCU.

In the application, the whole vehicle controller VCU has two wake-up modes, one wake-up mode is that the vehicle control unit BCM wakes up when receiving the power-up request, and the other wake-up mode is that the wake-up module wakes up directly. Under the condition that the wake-up module is directly waken up, the number of times of power-up faults is cleared, and the purpose is not to influence the next power-up request.

It should be noted that, no matter what way the power-up failure times are cleared, after the power-up failure times are cleared, the whole vehicle controller VCU controls the switch module 220 to be turned on so as to receive the next power-up request.

In some embodiments, the vehicle controller VCU is further configured to detect, after switching to the wake-up state, whether a power-up request is received, and if the power-up request is not received, whether the wake-up time exceeds a fourth preset threshold; and under the condition that the wake-up time exceeds a fourth preset threshold value, the whole vehicle controller VCU enters a dormant state.

In short, after the whole vehicle controller VCU is awakened, if no power-on request is made, and the awakening time is longer, the vehicle controller VCU automatically enters a dormant state; if the power supply request is made, the power supply is carried out when the upper high voltage condition is met; if there is a power-up request and the upper high voltage condition is not satisfied, the lower electrical storage chip EEPROM records the number of power-up faults, and when the number of power-up faults reaches a certain value, the switch module 220 is turned off. This avoids waking up the VCU back and forth due to a sustained high voltage failure. Until the VCU is awakened in a normal awakening manner (an awakening module), when power is turned on, the VCU clears the number of power-up faults recorded by the lower power storage chip eercom, and closes the switch module 220. Therefore, the function of the next power supply is not affected, and the VCU can be protected.

The embodiment of the application also provides a power supplementing method, and the power supplementing method is explained in detail below.

Fig. 4 is a schematic flow chart of a power supply method according to an embodiment of the present application, as shown in fig. 4, the power supply method 400 is applied to the foregoing power supply device, and the power supply method 400 may include: s401 to S405. The execution main bodies of the following steps are all the whole vehicle controller VCU.

S401, when the switch module is turned on, the switch module is switched from a sleep state to an awake state in response to an awake signal.

S402, in response to the power-up request in the awake state, if the vehicle meets the high-voltage power-up condition, the battery 201 is charged up.

In some embodiments, the upper high pressure conditions may include: only the pedal is taken down, the signal is effective, and DCDC is normal.

S403, acquiring the number of times of power-on fault when the vehicle does not meet the high-voltage power-on condition.

And S404, when the number of the power-on faults is greater than or equal to a first preset threshold value, the switch module is controlled to be disconnected.

S405, after the switch module is disconnected, the switch module enters a dormant state.

In conjunction with all the above embodiments, for convenience of understanding, fig. 5 is another flow chart of the power supply method according to the embodiment of the present application, and, as seen in conjunction with fig. 3 and fig. 5, the power supply method may include steps one to eight.

Step one, when the battery detection unit EBS judges that the electricity needs to be supplemented, an electricity supplementing request is sent to the vehicle control unit BCM through LIN communication.

And step two, after receiving the power supply request of the storage battery detection unit EBS, the vehicle control unit BCM outputs high level through a hard wire to wake up the whole vehicle controller VCU, and the step three is executed.

And step three, if the relay K1 is opened, stopping the flow, and if the relay K1 is closed, continuing to execute the step four.

Step four, the whole vehicle controller VCU is awakened by the vehicle control unit BCM, and whether a power supplementing request is received or not is judged; if not, executing the step five, and if so, executing the step six.

And step five, detecting whether the awakening time of the VCU exceeds a fourth preset threshold, if so, stopping the flow, enabling the VCU to sleep, and if not, continuing to execute the step four.

Step six, detecting whether the VCU meets the high-voltage power-on condition, if not, executing step seven, and if so, executing step eight.

Step seven, the VCU adds 1 to the number of power-up faults, and then writes the power-up faults into the lower electrical storage chip EEPROM, which is not less than a first preset threshold? If yes, the relay K1 is opened, then the VCU is dormant, and if not, the VCU is directly dormant.

And step eight, high voltage is applied to the whole vehicle, DCDC is enabled, and the storage battery is charged. Judging whether the voltage of the storage battery reaches the full charge condition, if so, the whole vehicle is put down to high voltage, and the VCU is dormant; if not, then step eight is continued.

The embodiment of the application provides a power supplementing method. Under the condition that the whole vehicle controller does not meet the high-voltage power-on condition, the detection control module can always send a power-on request, and as the whole vehicle controller can acquire the power-on fault times, when the power-on fault times are greater than or equal to a first preset threshold value, the control switch module is disconnected, so that a wake-up signal sent by the detection control module and the power-on request cannot reach the whole vehicle controller and wake up after meeting a certain number of times, and the situation that the whole vehicle controller is repeatedly waken and always does not sleep by the detection control module when the whole vehicle controller has the high-voltage fault is avoided, thereby achieving the effect of avoiding device loss, and not affecting the situation of successfully power-on when the whole vehicle controller meets the high-voltage power-on condition.
