The following describes embodiments of the present invention with reference to the drawings, and further details of the embodiments of the present invention, such as the connection relationships between the components, the functions of the components, the operation principles, and the like are described. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves.
To facilitate understanding of the conditions defined in the present invention, the states of the electric loads and the battery mounted on the vehicle when the vehicle is running will be described.
In the existing vehicle, a plurality of belt connection parts are arranged between an engine and a water tank, and one of the belt connection parts is connected with a generator of the vehicle. When the vehicle runs, the belt obtains power transmitted from the engine along with the running of the vehicle engine, the generator is driven by the belt to generate current, one part of the current is supplied to most vehicle-mounted electric loads of the vehicle, and the other part of the current is used for charging a vehicle-mounted storage battery. Therefore, when the vehicle runs, the vehicle-mounted electric appliance on the vehicle is supplied with power by the generator, and the storage battery is not involved in auxiliary power supply unless the load of the generator is too large. Under the parking condition, the vehicle-mounted electric load is supplied with power by the storage battery, particularly when the vehicle is started, the storage battery is required to provide larger current to supply power to a starter of the vehicle, and under the parking condition, the generator does not operate, the storage battery cannot obtain a supplementary power supply, and further the condition of power shortage of the storage battery occurs. Therefore, the continuous power supply of the vehicle battery is a very important link.
The following description of the embodiments is mainly based on the definition of the vehicle in the parking condition. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a power supply system according to a first embodiment of the invention. As shown in fig. 1, the power supply system includes a battery 10, an uninterruptible power supply 11, and a load module 12. The battery 10 is connected to an uninterruptible power supply 11 for charging/discharging, and the battery 10 is connected to a load module 12 for supplying power. Under the parking condition, when the residual electric quantity value of the uninterruptible power supply 11 is smaller than or equal to the first electric quantity threshold value, the voltage value of the uninterruptible power supply 11 is smaller than or equal to the first voltage threshold value, and the residual electric quantity value of the storage battery 10 is larger than or equal to the first preset value, the storage battery 10 charges the uninterruptible power supply 11, and meanwhile, the uninterruptible power supply 11 stops discharging; under the parking condition, when the residual electric quantity value of the uninterruptible power supply 11 is greater than the second electric quantity threshold value, the voltage value of the uninterruptible power supply 11 is greater than the second voltage threshold value, and the residual electric quantity value of the storage battery 10 is less than or equal to the second preset value, the uninterruptible power supply 11 charges the storage battery 10; the first electric quantity threshold value is smaller than the second electric quantity threshold value, the second voltage threshold value is larger than the first voltage threshold value, and the first preset value is larger than the second preset value.
Specifically, first, in the case where the vehicle is running, both the uninterruptible power supply 11 and the battery 10 are replenished with electric power by the vehicle generator, and at this time, the uninterruptible power supply 11 is in a discharge stop state. Until the remaining capacity of the ups 11 is greater than 95% (it is understood that the remaining capacity is a percentage value of the total capacity) and the voltage value of the ups 11 is greater than 12.8V, the generator stops charging the ups 11, although the specific values are not limited thereto, and are merely used as an example, and the relationship between the values may satisfy the foregoing description.
Under the parking condition, when the residual electric quantity value of the uninterruptible power supply 11 is less than or equal to 40%, the voltage value of the uninterruptible power supply 11 is less than or equal to 10.5V and the residual electric quantity value of the storage battery 10 is greater than or equal to 70%, the storage battery 10 charges the uninterruptible power supply 11, and meanwhile, the uninterruptible power supply 11 stops discharging; under the parking condition, when the residual electric quantity value of the uninterruptible power supply 11 is greater than 85%, the voltage value of the uninterruptible power supply 11 is greater than 12V, and the residual electric quantity value of the storage battery 10 is less than or equal to 40%, the uninterruptible power supply 11 charges the storage battery 10.
In an embodiment, when the remaining electric quantity value of the ups 11 is greater than a third electric quantity threshold and the voltage value of the ups 11 is greater than a third voltage threshold, or the remaining electric quantity value of the battery 10 is less than a third preset value, the ups 11 stops charging, wherein the third electric quantity threshold is greater than the second electric quantity threshold, the third voltage threshold is greater than or equal to the second voltage threshold, and the third preset value is less than or equal to the first preset value.
Specifically, for example, when the remaining electric power value of the uninterruptible power supply 11 is greater than 95% and the voltage value of the uninterruptible power supply 11 is greater than 12.8V, or the remaining electric power value of the secondary battery 10 is less than 70%, the uninterruptible power supply 11 stops charging. It should be noted that the stop of charging of the ups 11 means that the battery 10 charges the ups 11 in a parking condition, or the generator charges the ups 11 in a vehicle running condition.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a power supply system according to another embodiment of the present invention. As shown in fig. 2, in one embodiment, the ups 11 is connected to the load module 12 to provide power to the load module 12.

in particular, the sensor module is fitted above the negative pole of the battery 10 (not shown in fig. 3) for detecting the residual electric quantity value of the battery 10 and sending it to the uninterruptible power supply 11. The data processing module 112 may be a 16-bit μ C module, and is configured to calculate a residual electric quantity value of the ups 11, process data parameters such as a residual electric quantity value/voltage/current of the ups 11, and monitor the charging and discharging control module 113. The uninterruptible power supply 11 further includes a storage module for storing various data parameters inside the uninterruptible power supply 11. It should be noted that the parameters of the ups 11 are the parameters of the power body 110 in this embodiment.
In an embodiment, the charging and discharging control module 113 further includes an application algorithm module, and the application algorithm module is configured to output an optimal charging current value by using a BP genetic algorithm according to the residual electric quantity value and the voltage value of the uninterruptible power supply 11.
Specifically, the weight and the threshold of the BP network are optimized in parallel by using a genetic algorithm, that is, the residual electric quantity value and the voltage value of the uninterruptible power supply 11 are optimized, so that the defect that the BP network is locally optimal when the weight and the threshold are optimized is avoided, and the optimal charging current value is output.
In an embodiment, the uninterruptible power supply 11 further includes a filtering module, the filtering module is connected to the charge and discharge control module 113, and the filtering module uses a capacitor circuit to process the current so as to stabilize the charge and discharge current of the uninterruptible power supply 11.

Specifically, although the vehicle-mounted electric load is supplied with power by the generator during the running of the vehicle, the situation that the generator fails is not eliminated, and when the whole vehicle is subjected to a collision experiment, the vehicle-mounted electric load is supplied with power by the storage battery 10, and the voltage of the storage battery 10 is reduced to 2V in the range of 10ms to 90ms during the collision, so that the problem that the doors of some vehicles cannot be automatically unlocked is caused, and if the storage battery 10 is solely used for supplying power, the problem that the doors of some vehicles cannot be automatically unlocked during the collision is caused, so that the safety rating of the vehicles is influenced. In the embodiment, the storage battery 10 and the uninterruptible power supply 11 are used for supplying power together, and the storage battery 10 and the uninterruptible power supply 11 can be charged mutually to keep the normal working state of the storage battery 10 and the uninterruptible power supply 11, so that the problem can be solved well.
