Orientation or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of description the utility model and simplification
Description, rather than the device or element of instruction or hint meaning must have specific orientation, with specific azimuth configuration and behaviour
Make, therefore it is not intended that to limitation of the present utility model.
As shown in figure 1, fuel vehicle start battery power supply circuit include with two feeder ears to be used for be electrical equipment 1
The startup lithium battery group 3 powered with engine 2, electrical equipment 1, engine 2 are respectively connected between two feeder ears, are powered
Circuit also includes at least one super capacitor 4 being serially connected being connected between two feeder ears.I.e. start lithium battery group 3 with
Electrical equipment 1, engine 2 are in parallel respectively, and the super capacitor 4 being serially connected is as overall also in parallel with starting lithium battery group 3.Its
In, the capacitance of each super capacitor is preferably 350F, the quantity of super capacitor preferably >=5, and be serially connected.Other
In embodiment, super capacitor capacity can also change adjustment, as needed depending on, the scope of protection of the utility model it
It is interior.
Wherein, starting lithium battery group 3 includes at least one lithium battery 31 being serially connected and for detecting each lithium battery
Voltage battery controller 32.That is, the battery controller 32 can enter to the voltage of each lithium battery 31
Row detection.Specifically, battery pack controls 32 devices to be connected by multiple pins with the positive pole and negative pole of each lithium battery 31.
In the present embodiment, the quantity of lithium battery 31 is four and is serially connected, then battery controller 32 then by five pins with it is every
The positive pole of one lithium battery 31 is connected with negative pole.Specifically, two of which pin is connected to the lithium electricity of a wherein outermost end
