Specific embodiment
First embodiment
Fig. 1 is referred to, Fig. 1 shows that the flow for the vehicle energy optimum management method that the application first embodiment provides is shown
It is intended to, specifically comprises the following steps：
Whether step S110 judges battery capacity less than the first preset value, if so, performing step S120.
The concrete numerical value of battery capacity can be obtained by controller, controller is after the concrete numerical value of acquisition by itself and
Whether one preset value is compared, so as to judge the electricity of present battery less than the first preset value.If so, perform step
S120.Specifically, the first preset value can be the 15% of total electricity.
Step S120 if the battery capacity is less than first preset value, and receives compressor of air conditioner open command,
Then ignore the compressor of air conditioner open command.
When battery capacity is less than the first preset value, i.e., when battery capacity is less than the 15% of total electricity, then receive air-conditioning
During compressor open command, since electricity limits, compressor of air conditioner is not then turned on, to ensure there are enough electricity to supply electric vehicle
Operation.
Whether step S130 judges the battery capacity less than the second preset value, wherein, second preset value is less than institute
The first preset value is stated, if so, performing step S140.
Controller obtains the specific electricity of battery, since battery capacity is by aforementioned judgement, has been determined as less than the
One preset value, at this point, whether judging battery capacity again less than the second preset value, the second preset value is less than the one of the first preset value
A concrete numerical value, specifically, the second preset value can be the 10% of total electricity.If battery capacity is less than the second preset value, hold
Row step S140.
Whether step S140 judges the compressor of air conditioner in opening, if so, performing step S150.
Since electricity is already below the second preset value, it is in the state of more short of electricity.Therefore, can further judge
Whether compressor of air conditioner is in opening, if so, step S150 can be performed.
Step S150 sends out compressor of air conditioner out code.
Controller sends out compressor of air conditioner out code to compressor of air conditioner, to save electricity, better ensures that vehicle row
The continuation of the journey sailed.Controller can not only send out compressor of air conditioner out code, can be sent out warm wind out code.
The embodiment of the present application is detected to decide whether the equipment such as unlatching compressor of air conditioner by the surplus to power supply,
So as to fulfill optimizing management to vehicle energy.
Fig. 2 is referred to, Fig. 2 shows the specific steps schematic diagrames after step S150, specifically comprise the following steps：
