Electricity.First battery pack 1 is to be set to interior built-in rechargeable battery packet, and the second battery pack 2 is removably to change electric battery pack.
At a distance of very far, the electricity of current first battery pack 1 and the second battery pack 2 can not be arrived for the destination 30 of this navigation and starting point 10
Up to the destination of guidance path, if so, return step S300, if it is not, then return step 400.
As shown in figure 4, searching for nearest charging station discovery charging station 21 along guidance path, charging station 22, charging station 23, filling
Power station 24, charging station 25, charging station 26, charging station 27, charging station 28, charging station 29 and current location starting point 10, purpose
Ground 30 is used as network node, establishes the path between network node, forms network node map according to network node and path.
In a preferred embodiment, all-network node is traversed by starting point of the network node of current location, obtains net
By the first battery fully charged charging time and to second after the transit time in path between network node, and each node of arrival
What battery change electricity changes the electric time.
It in a preferred embodiment, is the center of circle from a upper node, the first current battery pack 1 and the second battery pack 2
The maximum distance that electricity can reach is for detection range destination in the range of radius apart from nearest network node as next
Node.Time needed for reaching each node is transit time, charging time and the sum of changes the electric time.
Various guidance path is generated by the path planning of these nodes in the present embodiment, only passes through exhibition below

Sail time T1, and to the charging time T2 that the first battery is fully charged estimated in recharging station 21 after charging station 21 and to the
What two batteries change electricity changes electric time T3.Charging time T2 refers to the first battery is required pre- from current electric quantity to what is be full of
Between timing, and changes electric time T3 and refer to the time needed for the second battery for replacing one block of full electricity.Self-charging station 21 reaches charging
Stand 24 time, include the running time T4 between charging station 21 and charging station 24, and to recharging station after charging station 24
In 24 the estimated charging time T5 that the first battery is fully charged and electric time T6 is changed to what the second battery change electricity.Self-charging
It stood for 24 times for reaching charging station 25, includes the running time T7 between charging station 24 and charging station 25, and arrive charging station
After 25 the charging time T8 that the first battery is fully charged estimated in recharging station 25 and electricity is changed to what the second battery change electricity
Time T9.Arrive at the destination 30 time of self-charging station 25 only includes running time T10 between charging station 25 and destination 30.
So carrying out the total time of path S1 are as follows: TS1=T1+T2+T3+T4+
T5+T6+T7+T8+T9+T10。
As shown in fig. 6, path S2 includes from starting point 10 successively by charging station 22, charging station 24, charging station 26, charging
It stands the process of 28 and destination 30, the total time for carrying out path S2 is TS2.Calculating about TS2 is referring to above, herein not
It repeats again.
