Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, general fuel vehicles are all provided with a parking air conditioner to provide better application driving experience for users. Since the driving environment of the vehicle may be in a hot or cold condition, the service time of the parking air conditioner may be long, and the general working power of the parking air conditioner is large, and further, in order to ensure the normal use of the parking air conditioner and the fuel vehicle, the parking air conditioner and the fuel vehicle are generally implemented in the following two ways:
1. for a vehicle only adopting a whole vehicle power battery pack, the whole vehicle power battery can independently supply power for electric equipment such as a parking air conditioner (high-power discharge equipment), and under the condition that the vehicle is in a static state and does not need to run, fuel oil does not need to be consumed to start a power assembly to supply power for the electric equipment. However, when the power assembly motor in the fuel vehicle is started, the power assembly motor is started to provide electric quantity through a power battery of the whole vehicle. At this time, two disadvantages exist, one of which is that the performance of the entire vehicle power battery pack is damaged due to the large current when the starting motor structure is started, and the other is that the motor structure cannot be started in a low-temperature environment (such as minus 20 ℃) due to the poor low-temperature starting performance of the entire vehicle power battery.
2. For a vehicle only using a starting battery pack, the starting battery needs to provide electric quantity for starting of a power assembly motor in the fuel vehicle and electrical equipment such as a parking air conditioner (high-power discharge equipment) at the same time, and in addition, a power generation assembly powered by fuel oil needs to supply power for the electrical equipment such as the parking air conditioner (high-power discharge equipment). At the moment, the power component of the fuel power drives the power generation component, if the fuel vehicle is in a static state and does not need to run, the electric equipment only adopts the fuel power for power supply, larger fuel is needed to be consumed, and the power component is seriously abraded. In addition, the high-power discharging equipment supplies power through the starting battery, so that the performance attenuation of the starting battery pack is serious, and the parking air conditioner cannot be supplied with power for a long time.
The starting operation of the starting motor structure simultaneously needs the combined action of the whole vehicle power battery pack and the starting battery pack, namely, the electric quantity of high-power electric equipment is provided by the whole vehicle power battery pack, so that the battery characteristic of the starting battery pack is ensured not to be lost. Although the defect problem of the implementation mode is solved, the current is relatively large when the starting motor structure is started, and the whole vehicle power battery pack has the battery characteristic of continuous discharging with small current, and when the times that the whole vehicle power battery pack and the starting battery pack jointly provide electric quantity for the starting operation of the starting motor structure are large, the battery characteristic of the whole vehicle power battery pack can be damaged to a certain extent.
Based on the above, the double-battery control system and the fuel vehicle provided by the embodiment of the invention can ensure the normal use of the parking air conditioner and the fuel vehicle, and simultaneously maintain the battery characteristics of the power battery and the starting battery of the whole vehicle.
The following is a detailed description by way of example.

In an alternative embodiment, the control unit 60 is further configured to monitor the voltage of the starting battery pack 30 when the ignition lock is in the power-on position, and to control the first electromagnetic contact 11 and the second electromagnetic contact 12 to open after a second preset time period when the voltage of the starting battery pack 30 reaches the voltage of the power generation assembly 53. At this time, the whole vehicle power battery pack 20 supplies power to the whole vehicle, so that the battery performance is prevented from being reduced due to the power feeding of the starting battery pack 30 when the starting motor structure 51 does not perform the starting operation.
Here, the second preset period of time may include 1 hour, at which time the starting battery pack 30 may be fully charged by up to about ninety percent.
