Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1: as shown in fig. 1 and fig. 2, an energy supply system for a new energy automobile comprises a control unit 1, a first battery pack 2, a second battery pack 3, a first battery switch 4 and a second battery switch 5, wherein the first battery switch 4 and the second battery switch 5 are connected to the control unit 1 for controlling the first battery pack 2 and the second battery pack 3 to sequentially operate, the energy supply system further comprises an electric quantity monitoring unit 6, an input end of the electric quantity monitoring unit 6 is connected to the first battery pack 2 and the second battery pack 3, an output end of the electric quantity monitoring unit 6 is connected to the control unit 1, the first battery pack 2 is larger than the capacity of the second battery pack 3, the internal combustion generator 7 is connected to the second battery pack 3, when the electric quantity of the second battery pack 3 reaches a preset value, the internal combustion generator 7 is started to charge the second battery pack 3, both the first battery pack 2 and the second battery pack 3 are electrically connected to a motor driver 9, the motor driver 9 is connected with an automobile driving motor 8. Preferably, the first battery pack 2 is operated prior to the second battery pack 3.
The working principle is as follows: at the beginning of the vehicle, the control unit 1 controls the first battery switch 4 to be closed, the first battery is put into operation before the second battery pack 3, the first battery pack 2 is used for providing energy output, and the capacity of the first battery pack 2 is large so as to ensure that the vehicle has enough power energy and running mileage. When the electric quantity of the first battery pack 2 is reduced to the lowest protection value, for example, 5KWh, the electric quantity monitoring unit 6 monitors and transmits a signal to the control unit 1, the control unit 1 controls the first battery switch 4 to be switched off after the second battery switch 5 is switched on, at the moment, the second battery pack 3 is put into operation, and the second battery pack 3 provides power energy for the vehicle. Further, when the second battery pack 3 is reduced to a certain value, the internal combustion generator 7 is started, at this time, the internal combustion generator 7 only supplements power for the second battery pack 3, the internal combustion generator 7 can generate power to keep the energy density of the second battery pack 3 all the time, at this time, only the second battery pack 3 still provides power for the vehicle, the automobile driving motor 8 is also ensured to obtain stable and reliable energy supply, the part of the excessive internal combustion generator 7, which is converted from oil to electricity, stored in the battery is effectively reduced, the part of the energy density of the second battery pack 3, which is kept all the time, is increased, and the shortage of excess oil-electricity conversion efficiency when the internal combustion engine generates electricity on new energy is favorably overcome. Through long-term research and experimental inventor, it is found that when the capacity of the second battery pack 3 is 15KWh-30KWh and the capacity of the first battery pack 2 is 3-6 times that of the second battery pack 3, the electric vehicle has the best cruising ability under the same test conditions.
On the basis of the scheme, a quick charger is selected to charge the first battery pack 2 and the second battery pack 3, and the connection relation of specific electrical components is as follows: the first battery pack 2 and the second battery pack 3 are respectively electrically connected to the output end of the charger 12, and the input end of the charger 12 is connected to a charging socket (not shown). Preferably, the second battery pack 3 is automatically charged after the first battery pack 2 is fully charged at the time of charging to ensure a large capacity of the first battery pack 2 with sufficient electric power, and then the operation of the second battery pack 3 is reduced as much as possible to reduce unnecessary operation of the internal combustion generator 7.
Preferably, a first plug-pull piece 10 is connected between the first battery pack 2 and the charger, and a second plug-pull piece 11 is connected between the second battery pack 3 and the charger. The advantage of this arrangement is that when the charger fails, the external charger of the system can be selected directly through the first plug member 10 and the second plug member 11 to charge the vehicle quickly without waiting for the maintenance of the charger, and the vehicle can be charged at the same time of the maintenance of the charger.
