So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
An embodiment of the present invention provides a charging control method, which is applied to a vehicle having a charging control device, and as shown in fig. 1, the method mainly includes:
The vehicle is a vehicle which needs a starter to obtain electric quantity capable of driving a crankshaft of the engine to rotate when the engine is ignited; wherein the starter is connected with the engine.
Optionally, the vehicle is a vehicle having a first power source (also commonly referred to as a battery). The electric quantity in the storage battery is at least used for supplying power to a starter connected with the engine so as to meet the requirement that the starter drives the crankshaft of the engine to rotate and realize the successful starting of the engine. For example, the vehicle may be a vehicle having a battery, such as a conventional automobile, a plug-in hybrid automobile, an electric automobile, or the like.
In one embodiment, the acquiring the electric quantity of the first power source of the vehicle includes:
monitoring status information of an engine of the vehicle;
and when the state information meets a first preset condition, acquiring the electric quantity of a first power supply of the vehicle.
Wherein the first preset condition comprises:
the state of the engine of the vehicle for N times is failed in starting; wherein N is a positive integer.
Here, the value of N may be set actively by a user or set by the charging control device according to actual conditions. For example, the charge control device may be set according to environmental factors such as altitude, air pressure, temperature and humidity.
Illustratively, the charge control device adjusts the value of N according to seasonal variations, setting N to 3 for winter; for spring and autumn, the charging control device sets N to 2; for summer, N is set to 1.
And 102, judging whether the electric quantity of the first power supply is lower than a first threshold value.
Here, the first threshold may be a minimum value of the amount of electricity that the starter is supported to rotate the crankshaft of the engine, or may be greater than the minimum value, and may be set according to actual needs.
And 103, if the electric quantity of the first power supply is lower than the first threshold, judging whether the electric quantity of a second power supply of the vehicle-mounted electronic equipment is higher than a second threshold.
The vehicle-mounted electronic equipment is electrically connected with the charging control equipment of the vehicle.
Here, the in-vehicle electronic apparatus is an electronic apparatus having a second power source, for example, a battery.
For example, the vehicle-mounted electronic device may be a walk-substituting tool having a battery, such as an electric balance car, an electric scooter, or the like. The vehicle-mounted electronic equipment can also be a portable charger integrating power supply and charging functions, such as a vehicle-mounted charger.
And 104, if the electric quantity of the second power supply is higher than the second threshold value, controlling the vehicle-mounted electronic equipment to charge the first power supply of the vehicle.
In an optional embodiment, the controlling the in-vehicle electronic device to charge the vehicle includes:
controlling the first power supply and the starter to change from a connection state to a disconnection state;
and controlling the first power supply and the vehicle-mounted electronic equipment to change from the unconnected state to the connected state.
Fig. 2 is a schematic diagram illustrating a connection relationship between a charging control device and a vehicle-mounted electronic device according to an embodiment of the present invention; as shown in fig. 2, the vehicle 10 includes a charge control apparatus 11, a first power source 12, a starter 13, an engine 14; the charging control device 11 is connected with a first power supply 12, the first power supply 12 is connected with a starter 13 through a normally closed relay 15, and the starter 13 is connected with an engine 14; the first power supply 12 is further provided with a normally open relay 16 at one end, and the normally open relay 16 is changed from an unconnected state to a connected state with the in-vehicle electronic device 20 when receiving the second control instruction.
Specifically, one end of the normally closed relay 15 is connected to a first end of the first power supply 12, and the other end of the normally closed relay 15 is connected to the starter 13; one end of the normally open relay 16 is connected to the second end of the first power source 12, and the other end of the normally open relay 16 may be connected to the in-vehicle electronic device 20.
In one embodiment, the controlling the first power source and the starter to be in a disconnected state from the connected state includes:
generating a first control instruction, and controlling a normally closed relay to be changed from a closed state to an open state based on the first control instruction; one end of the normally closed relay is connected with the first end of the first power supply, and the other end of the normally closed relay is connected with the starter;
the control of the first power supply and the vehicle-mounted electronic equipment from the unconnected state to the connected state includes:
generating a second control instruction, and controlling the normally-open relay to be changed from an open state to a closed state based on the second control instruction; one end of the normally open relay is connected with the second end of the first power supply, and the other end of the normally open relay is connected with the vehicle-mounted electronic equipment.
That is to say, when the electric quantity of the first power source 12 is not lower than the first threshold, the first power source 12 and the starter 13 are in a connection state through the normally closed relay 15, and the first power source 12 supplies power to the starter 13, so as to meet the requirement that the starter 13 drives the engine 14 to rotate by the crankshaft, and the engine 14 is successfully started. When the electric quantity of the first power supply 12 is lower than a first threshold value, the normally closed relay is changed from a closed state 15 to an open state, and the first power supply 12 and the starter 13 are changed from a connected state to an open state; the normally open relay 16 changes from the open state to the closed state, changing the first power supply 12 and the in-vehicle electronic device 20 from the unconnected state to the connected state, thereby enabling the in-vehicle electronic device 20 to charge the first power supply 12.
In an optional implementation, the controlling the in-vehicle electronic device to charge the vehicle further includes:
detecting the electric quantity of the first power supply;
judging whether the electric quantity of the first power supply is higher than a third threshold value;
and when the electric quantity of the first power supply is higher than the third threshold value, controlling the first power supply and the starter to change from a disconnected state to a connected state.
Here, the third threshold value may be equal to the first threshold value; the third threshold may also be greater than the first threshold, but a difference between the third threshold and the first threshold is less than or equal to a preset value.
That is to say, when the vehicle-mounted electronic device charges the first power supply, if the electric quantity stored in the first power supply reaches the third threshold value, the first power supply and the starter are controlled to be changed from a disconnected state to a connected state, so that the electric quantity in the first power supply can meet the requirement that the starter drives the engine, the engine can be started successfully, and the engine can be started as soon as possible when the electric quantity of the first power supply reaches the third threshold value.
In an optional implementation, the controlling the in-vehicle electronic device to charge the vehicle further includes:
when the state of the engine is detected to be changed from failed start to successful start,
and controlling the first power supply and the vehicle-mounted electronic equipment to be changed from a connection state to a disconnection state.
That is, when the in-vehicle electronic device 20 charges the first power supply 12, if it is detected that the state of the engine 14 has changed from failed to successful, the first power supply 12 can be charged and the connection with the in-vehicle electronic device 20 is disconnected after the engine 14 has been successfully started, so that the amount of power of the in-vehicle electronic device 20 can be saved.
In an optional implementation, the controlling the in-vehicle electronic device to charge the vehicle further includes:
detecting the power type of a power supply port of the vehicle-mounted electronic equipment; wherein the power supply port is used for supplying power to the vehicle;
and if the power type is alternating current, rectifying the alternating current output by the power supply port, and charging the first power supply by using the direct current obtained after rectification.
Here, the first power source is charged by direct current; if the vehicle-mounted electronic equipment outputs alternating current, the alternating current needs to be rectified firstly, and then the rectified direct current is used for charging so as to protect a first power supply in a vehicle.
In an embodiment, the method further comprises: when the power supply voltage of the first power supply reaches a preset voltage threshold value, the first power supply supplies power to the charging control equipment; when the power supply voltage of the first power supply does not reach a preset voltage threshold value, switching to a mode that a second power supply of the vehicle-mounted electronic equipment supplies power to the charging control equipment;
and under the condition that the second power supply of the vehicle-mounted electronic equipment supplies power to the charging control equipment, when the condition that the starting failure of the engine is changed into the starting success is detected, the first power supply is switched to supply power to the charging control equipment.
Here, the charge control apparatus requires a certain amount of electricity to monitor the state information of the vehicle engine, and performs a corresponding control operation when the state information of the vehicle engine satisfies a first preset condition. Generally, the amount of power required by the charging control device is much smaller than that required by the starter, that is, when the amount of power in the first power source is not enough to supply to the starter, it is possible to maintain the amount of power required by the charging device; when the electric quantity in the first power supply is not enough to maintain the electric quantity required by the charging control equipment, if the electric quantity of the first power supply is 0, the vehicle-mounted electronic equipment can be charged for the charging control equipment in a mode of switching a power supply interface; when the state of the engine is detected to be changed from the failed starting to the successful starting, the charging control equipment is switched to the first power supply to supply power to the charging control equipment due to the fact that the engine can supply power to the first power supply successfully after the engine is started, and therefore the electric quantity of the vehicle-mounted electronic equipment can be saved.
In the technical scheme of the embodiment, the charging control equipment acquires the electric quantity of a first power supply of the vehicle; judging whether the electric quantity of the first power supply is lower than a first threshold value; if the electric quantity of the first power supply is lower than the first threshold, judging whether the electric quantity of a second power supply of the vehicle-mounted electronic equipment is higher than a second threshold; the vehicle-mounted electronic equipment is electrically connected with the charging control equipment of the vehicle; and if the electric quantity of the second power supply is higher than the second threshold value, controlling the vehicle-mounted electronic equipment to charge the first power supply of the vehicle. Therefore, when the electric quantity of the first power supply of the vehicle is lower than the first threshold value, if the electric quantity of the vehicle-mounted electronic equipment electrically connected with the charging control equipment of the vehicle is higher than the second threshold value, the vehicle-mounted electronic equipment is controlled to charge the first power supply of the vehicle, so that the vehicle can be charged through the vehicle-mounted electronic equipment, and the problem that the vehicle cannot be started when the electric quantity of the first power supply of the vehicle, such as a storage battery, is too low is solved.
