As shown in fig. 2, in an embodiment, the endurance processor 14 of the electric vehicle body 10 may be a processor having a computing capability, such as a Micro Control Unit (MCU) or a Micro Processing Unit (MPU). The cruising processor 14 may obtain power supply vehicle replacement information according to the position information P output by the global positioning device 12, the destination information D input by the input unit 13, and the electric quantity information of the battery module 21 of the external power supply vehicle 20, wherein the power supply vehicle replacement information includes geographic information of at least one power supply vehicle replacement station R. In one embodiment, the electric vehicle body 10 or the external electric vehicle 20 may have a power detector (not shown) for detecting and obtaining the power information of the battery module 21 and providing the power information to the endurance processor 14.
As shown in fig. 2, in an embodiment, the electric vehicle body 10 may include a map database 19, the map database 19 includes geographic information of a plurality of electric vehicle replacement stations R and is electrically connected to the endurance processor 14, and the endurance processor 14 may calculate and obtain the electric vehicle replacement information from the map database 19 according to the position information P, the destination information D and the electric quantity information of the battery module 21. As shown in fig. 3, the endurance processor 14 may output a real-time electronic map M, on which the position information P (i.e. the real-time position of the electric vehicle) and the geographical position of the power supply vehicle replacement station R between the destination and the electric vehicle position may be indicated, wherein the power supply vehicle replacement station R may have the external power supply vehicle 20 therein for replacement. Therefore, the driver can know exactly where the external power supply vehicle 20 can be replaced in the process of driving to the destination, so that the electric vehicle can maintain endurance, long-distance driving is facilitated, and the driver can feel secure in the driving process.
In one embodiment, when the electric quantity information of the battery module 21 is smaller than the stored electric quantity value, the geographic information of the power supply vehicle change station R is the geographic information of the power supply vehicle change station R closest to the position information. For example, as shown in fig. 2 and fig. 3, the cruising processor 14 may only output the geographical information of the power supply vehicle replacement station R closest to the position information P when the electric quantity value of the battery module 21 is less than 20% (i.e., the stored electric quantity value), so as to remind the driver to replace the external power supply vehicle 20 with a new external power supply vehicle as soon as possible. In addition, in an embodiment, the endurance processor 14 may simultaneously send out a warning signal to remind the driver that the power information of the battery module 21 is smaller than the stored power value, for example, the warning signal may control a buzzer to send out an alarm or control the power supply vehicle change station R on the real-time electronic map M to flash.
In some embodiments, the geographic information of the power supply vehicle replacement station R closest to the position information P may be obtained by calculation of the cruising processor 14 itself, or by calculation of a device (e.g., a cloud device) outside the electric vehicle body 10.
In an embodiment, as shown in fig. 3, the cruising processor 14 may obtain a planned driving route T according to the destination information D and the position information P, and the geographic information of the power supply vehicle changing station R may be located on the planned driving route T. For example, the cruising processor 14 may be a processor of a navigation device, the destination information D input by the driver and the position information P of the electric vehicle calculate a navigation path (i.e. the driving schedule path T marked on the electronic map M of fig. 3), and the cruising processor 14 may mark only the geographic information of the power supply vehicle replacement station R located on the driving schedule path T, for example, only the geographic information of the power supply vehicle replacement station R within 1 km from the driving schedule path T. Therefore, the driver can replace the external power supply vehicle 20 with a new one nearby during the driving along the driving planning path T, thereby further saving time. In other embodiments, the cruising processor 14 may also transmit the destination information D and the position information P to an external device (e.g., a cloud computing device) through the communication unit, and the external device calculates the driving schedule path T and then transmits the driving schedule path T back to the cruising processor 14, which is not limited thereto.
In one embodiment, the replacement information of the electric vehicle may be calculated by a device external to the electric vehicle body 10. As shown in fig. 4, which is a system block diagram of a second embodiment of the power assisting system of the electric vehicle according to the present invention, in the present embodiment, the electric vehicle body 10 includes a wireless communication unit 18, such as a WiFi module, an IEEE802.11 module, or a cellular communication module (cellular system). The endurance processor 14 wirelessly sends the position information P, the destination information D, and the electric quantity information of the battery module 21 to a device (e.g., a cloud computing device) outside the electric vehicle body 10 through the wireless communication unit 18 to calculate and obtain the replacement information of the power supply vehicle, and the wireless communication unit 18 wirelessly receives and obtains the replacement information of the power supply vehicle returned by the external device and returns the replacement information to the endurance processor 14.
As shown in fig. 4, the power assisting system 1 may include a cloud server 30, and the cloud server 30 is connected to the wireless communication unit 18 of the electric vehicle body 10 in a wireless communication manner to receive the position information P, the destination information D and the electric quantity information of the battery module 21, and accordingly calculates the replacement information of the electric vehicle and transmits the replacement information back to the wireless communication unit 18. Thus, the calculation amount of the endurance processor 14 of the electric vehicle body 10 can be reduced.
As shown in fig. 3 and 4, in an embodiment, the cruising processor 14 can wirelessly output a power supply vehicle reservation information B to the power supply vehicle changing station R through the wireless communication unit 18 to reserve the external power supply vehicle 20 in the power supply vehicle changing station R, so as to prevent the driver from having no external power supply vehicle 20 available for changing when driving to reach the power supply vehicle changing station R.
As shown in fig. 4, in an embodiment, the external power supply vehicle 20 further includes a wireless charging unit 24, and the wireless charging unit 24 is electrically connected to the battery module 21. For example, the wireless charging unit 24 may be an induction coil, which generates electromagnetic induction when approaching the charger, and further generates induction current to charge the battery module 21. Thus, the driver can drive to the charging station with the wireless charger to charge the battery module 21 without detaching the external power supply vehicle 20.
As shown in fig. 5, in an embodiment, the battery module 21 of the external power supply vehicle 20 may include at least one battery pack 211 (e.g., two battery packs 211 in the present figure), and the vehicle replacement information may further include a required number of battery packs 211, that is, the driver may further know the number of battery packs 211 needed to go to the destination through the vehicle replacement information, so that the driver can know the required number of battery packs 211 in advance and estimate the cost and plan which vehicle replacement stations R should be used for replacing the external power supply vehicle 20 in advance. Alternatively, in another embodiment, the power supply vehicle replacement station R may have a plurality of different external power supply vehicles 20, the number of battery packs 211 of the battery modules 21 carried by each external power supply vehicle 20 is different, and if the driver knows that the required number of battery packs 211 is large through the power supply vehicle replacement information, the external power supply vehicle 20 with the large number of battery packs 211 may be selectively replaced, so as to reduce the number of times of replacing the external power supply vehicle 20.
Referring to fig. 5, a system block diagram of a third embodiment of the electric power assisting system for an electric vehicle according to the present invention is shown, wherein the electric vehicle body 10 itself may include a battery 111, the battery 111 is electrically connected to the electric motor 11, the endurance processor 14 is further electrically connected to the battery 111, the battery module 21 of the external electric vehicle 20 may include two sets of battery packs 211, and the endurance processor 14 may control the two sets of battery packs 211 to simultaneously supply power to the electric motor 10, or control the two sets of battery packs 211 to respectively supply power to the electric motor 11 and the battery 111. In some embodiments, the battery cell 111 may be a rechargeable battery such as a fuel cell, a chemical battery, a solar cell, a lithium ion battery, a lithium polymer battery, a nickel metal hydride battery, a lead acid battery, or a lithium battery.
For example, the endurance processor 14 may obtain a remaining electric energy value of the battery 111, the endurance processor 14 controls the two battery sets 211 to simultaneously supply power to the electric motor 11 when the remaining electric energy value is greater than a threshold value, and the endurance processor 14 controls the two battery sets 211 to respectively supply power to the electric motor 11 and the battery 111 when the remaining electric energy value is less than the threshold value. For example, when a remaining capacity value of the battery 111 is less than 15% of the total capacity, the endurance processor 14 controls one of the battery packs 211 to supply power to the electric motor 11 and the other battery pack 211 to supply power to the battery 111. Therefore, when the user still cannot reach the service vehicle replacement station R when the power of the battery module 21 is exhausted, the storage battery 111 can be used to continuously supply power to the electric motor 11 to avoid the dilemma of breaking down.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
