It sails in some turn-round of route terminal, it is battery A and battery B respectively that each bus, which is equipped with two pieces of batteries,；
(B) each charging unit has the charging current and charging voltage of setting, i.e., each charging unit can be in the model of setting
Enclose interior adjusting unit time charge volume q；
(C) detection of battery capacity is carried out to it when each bus is outbound out of electrical changing station and charges to computer automatically
It is interior, when bus, which has travelled one, is again introduced into electrical changing station afterwards back and forth, the electricity of its battery is detected and passes through calculating
Machine is compared with its battery capacity when previous outbound, power consumption X in one driving process back and forth is calculated, by upper
The secondary outbound time T to this during entering the station, the unit time charge volume q of charging unit is obtained according to the charging curve of battery
Upper limit value qmax, then according to qmaxObtain the charging unit in time T to the maximum charge amount R of battery,
Wherein t represents time variable；
(D) as X≤R, battery A currently in use on the bus is replaced, replaced battery A is put into charging dress
It sets and charges, another piece of reserve battery B is changed on bus, after waiting the bus to turn again to electrical changing station, battery B is changed
Under charge, battery A is changed on bus；
(E) as X > R, illustrate on the bus battery A currently in use close to the terminal of service life, i.e. battery A
Charge and discharge ability be decreased obviously, battery A is changed superseded, and changes bus with one piece of new battery.
The utility model has the advantages that changing battery methods using above-mentioned, two pieces of uses need to be only equipped with by making each bus in the process of running
Battery, that is, battery A and battery B is further provided with a small amount of new battery, can ensure the normal operation of electric bus, save public transport
The battery amount of purchase and operation cost of vehicle operator, improve the utilization rate of battery, reduce the quantity of spare new battery.The party
Method, which makes each bus enter charging station, can carry out the replacement of battery, can prevent bus travel in battery overdischarge
Behavior remains at the electricity in battery in the reasonable interval of setting, plays the role of protecting battery, further improve
The service life of battery reduces the purchase cost of battery.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
Below with reference to Fig. 1, the invention will be further described.
A kind of replacing options of electric bus battery, comprising the following steps:
(A) more than two charging units are installed in the electrical changing station of Electric Transit, which is arranged in public transport garage
It sails in some turn-round of route terminal, it is battery A and battery B respectively that each bus, which is equipped with two pieces of batteries,；
(B) each charging unit has the charging current and charging voltage of setting, i.e., each charging unit can be in the model of setting
Enclose interior adjusting unit time charge volume q；
