Specifically, referring to fig. 1, the control device of the vehicle-mounted charger disclosed in this embodiment includes a control module 100, a determination module 200, a primary power module 300, and a secondary power module 400.

The primary power module 300 is used to power the control module 100 in the enabled state.

The secondary power module 400 is used for supplying power to the main function module of the vehicle-mounted charger in an enabled state.

The judgment module 200 may be powered by the primary power module 300 or the secondary power module 400.

In a working state, that is, in a state where the primary power module 300 supplies power to the control module 100 and the secondary power module 400 supplies power to the main function module of the vehicle-mounted charger, the control module 100 is configured to forward the wake-up signal to the determination module 200 when receiving the wake-up signal, where the wake-up signal may be an external wake-up signal, such as a control pilot signal CP and a key start signal when an external charging gun is inserted into the vehicle-mounted charger, and the control pilot signal CP is a level or periodic level signal PWM, and the signal exists as long as the charging gun is connected to the vehicle-mounted charger. The wake-up signal may also be an internal system wake-up signal, such as a wake-up signal generated by a power management module, a power distribution module, a vehicle controller, and the like.

The judging module 200 is configured to judge whether the wake-up signal is valid, if the wake-up signal generated by the CP of the vehicle-mounted charger still exists after charging is completed, but it is detected that the battery voltage and the charging current have reached a full-power state, the wake-up signal generated by the CP is an invalid signal, and if it is judged that no valid wake-up signal exists, if it is judged that the external wake-up signal is invalid and no other internal system wake-up signal is received, it is judged that no valid wake-up signal exists, and the judging module 200 sends a prompt message indicating that no valid wake-up signal exists to the control module 100.

The control module 100 is further configured to control the secondary power module 400 to power off when receiving the prompt message that the judging module sends no valid wake-up signal, so that the vehicle-mounted charger enters a shallow sleep state.

Further, the control module 100 is further configured to control the primary power module 300 to power down when the wake-up signal is not received within a preset time period, so that the control device of the vehicle-mounted charger and the vehicle-mounted charger both enter a deep sleep state. That is, the condition that the primary power module is powered off is that no wake-up signal exists, and if the wake-up signal is still present, the primary power module is not powered off even if the wake-up signal is an invalid wake-up signal, so that frequent powering off and frequent waking up of the primary power module under the condition that the invalid wake-up signal exists all the time are avoided.

It can be seen that, the control device of the vehicle-mounted charger disclosed in this embodiment performs two-stage hierarchical wake-up and sleep control on the vehicle-mounted charger, and even when the vehicle-mounted charger fails and the vehicle-mounted charger is charged completely, the wake-up signal always exists due to the fact that the charging gun is always connected to the vehicle-mounted charger, and the judgment module can also judge that the wake-up signal is an invalid wake-up signal, so that the control module controls the secondary power module to power down, and therefore the vehicle-mounted charger enters a shallow sleep mode, only the primary power module with low power consumption enables at this time, unnecessary power loss is effectively reduced, and the endurance time of the low-voltage storage battery of the whole vehicle is prolonged.

The control module 100 controls the enabling of the secondary power module 400 to supply power to the main function module of the vehicle-mounted charger and realize two-stage hierarchical awakening control under the condition of receiving the effective awakening signal prompt message sent by the judgment module 200. If the control module 100 receives the prompt message of no valid wake-up signal sent by the determination module 200 and does not receive the wake-up signal within the preset time, the primary power module 300 is controlled to be powered off, and the control device enters the deep sleep state again.

When the determining module 200 is powered by the secondary power module 300 in the enabled state, in the deep sleep state, the control module 100 is further configured to control the primary power module 300 and the secondary power module 400 to be enabled under the condition that the wake-up signal is received, so that the secondary power module 300 supplies power to the determining module 200.

The determining module 200 receives the wake-up signal forwarded by the control module 100 in an operating state, and determines whether the wake-up signal is valid. The control module 100 is further configured to, when receiving the valid wake-up signal prompt message sent by the determination module 200, continue to control the enabling of the secondary power module 400 to supply power to the main function module of the vehicle-mounted charger.

Further, in the case that the determination module 200 is powered by the secondary power module 300 in the enabled state, in order to avoid that the control module 100 controls the secondary power module 400 to power down after receiving the prompt information of no valid wake-up signal sent by the determination module 200, the determination module 200 does not work any more, which results in that no valid wake-up signal prompt information is lost and the secondary power module is waken up by an external invalid wake-up signal continuously. Referring to fig. 3, in the present embodiment, a latch module 500 is disposed in the control device of the vehicle-mounted charger, the latch module 500 may be a status latch, an edge trigger, or the like, and the latch module 500 is powered by the primary power module 300.

The determining module 200 is further configured to send a prompt message indicating that there is no valid wake-up signal to the latching module 500 when it is determined that there is no valid wake-up signal. The latch module 500 is configured to store the prompt message of no valid wake-up signal and send the prompt message of no valid wake-up signal to the control module 100. The control module 100 is further configured to control the secondary power module 400 to power down when receiving the prompt message of no valid wake-up signal sent by the latch module 500, and control the primary power module 300 to power down when not receiving the wake-up signal within a preset time period. After the primary power module 300 is powered off, the prompt message of no valid wake-up signal stored in the latch module 500 is cleared.

Further, in order to subdivide the functions of the control module 100 disclosed in the above embodiments, please refer to fig. 4, the control module includes a detection module 101 and a power enable module 102.

The detecting module 101 is configured to receive the wake-up signal, send the wake-up signal to the determining module 200, and receive the prompt message of the valid wake-up signal or the prompt message of the invalid wake-up signal sent by the determining module 200.

And the power supply enabling module 102 is used for controlling the primary power supply module 300 and the secondary power supply module 400 to be enabled or powered down under the control of the detection module 101.

In summary, when the control device of the vehicle-mounted charger and the vehicle-mounted charger are in deep sleep states and an external wake-up signal exists, the power enabling module 102 enables the primary power module 300 and the secondary power module 400 at the same time, the secondary power module 400 supplies power to the judging module 200 and the main function module of the vehicle-mounted controller, and when the judging module 200 judges that the wake-up signal is invalid, the latch module 500 is controlled to output a latch signal to the power enabling module 102, so that the secondary power module 400 is controlled to be powered off, so that only the primary power module 300 and the corresponding low-power-consumption module work, and the main function module and the judging module 200 of the vehicle-mounted controller are in shallow sleep states and have low loss. When the external wake-up signal disappears and no other wake-up signal exists, the primary power module 300 is powered off, the control device of the vehicle-mounted charger and the vehicle-mounted charger are all in a deep sleep state, and the electrical signal latched by the latch module 500 in the primary power module 300 is cleared, so that the situation that the secondary power module 400 cannot be enabled in the presence of the external wake-up signal next time can be avoided.

It should be noted that other wake-up signals may also enable the second power module 400 through the power enable module 102, and particularly when the second power module 400 further supplies power to the non-vehicle charger function module, such as an all-in-one product integrated with other function modules, if there is no other wake-up signal, the second power module 400 is in a power-off state when the external wake-up signal is invalid. In addition, the hierarchical awakening and dormancy control strategy is also suitable for other similar occasions, such as timely dormancy of a whole vehicle power supply system when a vehicle key is forgotten to be pulled out, low power consumption is guaranteed, and cruising ability is improved.
