[0003] Existing battery-swap electric vehicles and extended-range electric vehicles are equipped with external charging ports. These ports and charging systems serve only as a backup for range anxiety. Battery-swap vehicles can swap batteries faster than refueling, and are now widely used in taxis and other commercial vehicles. However, battery-swap refueling stations are primarily located in bustling urban areas, with fewer stations in suburban or remote areas. This leads to continued range anxiety for taxis during long-distance operations.

[0004] Extended-range electric vehicles can be powered by either oil or electricity, so there is no need to worry about range anxiety. However, compared to pure electric vehicles, extended-range vehicles have an additional fuel engine and generator, and also have their own fast-charging and slow-charging systems. The system is complex, resulting in higher manufacturing costs for extended-range vehicles. The high selling price has affected the acceptance and market share of extended-range vehicles. Summary of the Invention

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0048] Example 1

[0049] A battery-swap, range-extended electric vehicle without a charging port, comprising a battery-swap, range-extending unit, a drive motor, and a control unit.

[0050] As shown in Figures 1 and 2, the battery exchange unit includes a battery exchange battery 1 and a battery exchange lock body 2. The battery exchange battery 1, the drive motor, and the range extender unit are electrically connected to the control unit respectively, and the vehicle is not provided with an external charging port 56 and a charger 55 for replenishing power for the battery exchange battery 1 or the drive motor.

[0051] The existing battery replacement technology is fixed to the bottom of the vehicle's chassis through a battery replacement lock body 2. When the battery power is low, the vehicle needs to drive into a battery replacement station and use the battery replacement mechanism of the battery replacement station to quickly remove the battery replacement battery and replace it with a fully charged new battery.

[0052] Therefore, in the battery-swap extended-range electric vehicle of the present invention, the battery-swap battery can also be removed from the battery-swap extended-range electric vehicle. When the battery-swap battery on the vehicle is low on power, it can be replaced with another fully charged standard battery-swap battery. Since the present invention also provides an extended-range unit, the range extension can solve the anxiety of energy replenishment (using the existing complete refueling facilities), and the battery swap can also quickly replace the battery. In cities where there are battery swap stations and battery swaps are possible, the battery can be swapped at the battery swap station, and in places where there are no battery swap stations, refueling can be done directly. Therefore, the built-in charger and the high-voltage and low-voltage charging systems become a redundant setting. The existence of these two systems increases the difficulty of the system circuit and control system. By removing the charging port and the high or low-voltage charger, the purpose of reducing costs can be achieved while greatly simplifying and optimizing the control difficulty and integration difficulty of the connection circuit and control module. The motor driver can be used to directly control the battery.

[0053] In a feasible implementation manner, the vehicle includes wheels 57 and adopts a front-rear drive or four-wheel drive arrangement. The vehicle is provided with a front-wheel drive motor 61 at the front end and a rear-wheel drive motor 62 at the rear end. In this embodiment, the built-in charger 55 of the vehicle and the charging port 56 provided on the vehicle body are eliminated. At this time, the charger 55 and the charging port 56 represented by the dotted lines in Figure 1 represent components that can be eliminated.

[0054] As shown in FIG1 and FIG2 , a feasible implementation method is that the vehicle adopts a front-wheel drive arrangement, and the vehicle is only provided with a front-wheel drive motor 61 at the front end, while the vehicle's built-in charger 55 and the charging port 56 provided on the vehicle body are cancelled.

[0055] Furthermore, as shown in Figures 1, 2 and 3, the battery-swap battery 1 can be quickly connected to the bottom of the vehicle frame 4 through the battery-swap lock body 2.

[0056] As shown in Figure 4, the battery-swap lock 1 is also equipped with a quick-change water connector 11 and a quick-change electrical connector 12. These connectors are mature technologies in the market. The quick-change water connector 11 and the quick-change electrical connector 12 are connected to the control unit via an interface provided on the vehicle.

[0057] Furthermore, as shown in Figures 2 to 4, a avoidance groove 3 is provided on the top of the battery-swap battery 1. By providing a avoidance groove on the battery-swap battery, as shown in Figure 2, the avoidance groove 3 can provide a larger installation and disassembly space for the battery-swap battery 1 when the battery is swapped, so that the demand for battery swapping can be met. At the same time, when the battery is swapped, the exhaust pipe will not be affected and the exhaust pipe does not need to be disassembled. The cavity formed in the avoidance groove 3 is used to accommodate the exhaust pipe 51 and / or the oil pipeline of the vehicle-mounted wiring harness and / or the range extender unit. The oil pipeline is connected to the fuel tank 52 provided at the rear end of the vehicle, and the fuel tank 52 is connected to the external refueling port (not shown).

[0058] Furthermore, as shown in Figures 2 to 4, a quick-change water connector 11 and a quick-change electric connector 12 are provided on the top of the battery-swap battery 1. The quick-change water connector 11 can quickly complete a water connection with the vehicle's cooling system, and the quick-change electric connector 12 can quickly complete an electrical connection with the vehicle's internal system. On the one hand, it delivers electricity to the vehicle for use, and on the other hand, the internal control unit of the battery-swap battery 1 also quickly connects to the vehicle's control unit and accepts its control.

[0059] Furthermore, as shown in FIG5 , another feasible embodiment is that the quick water-change connector 11 and the quick electric connector 12 are arranged in the avoidance groove 3. In this case, the quick water-change connector 11 and the quick electric connector 12 are arranged in the avoidance groove 3 and close to the battery 1. This layout can avoid reserving installation space in the battery, ensuring that the battery is a complete whole. This can reduce the assembly and manufacturing difficulty of the battery, and prevent the quick water-change connector 11 and the quick electric connector 12 from affecting the battery when they are damaged or replaced. This can further improve safety.

[0060] Furthermore, the number of the avoidance groove 3 is 1. The avoidance groove 3 is set on the left side, right side or between the left and right sides of the battery 1. According to the layout requirements of the entire vehicle, the avoidance groove can be set in the middle or on both sides of the battery.

[0061] Furthermore, as shown in FIG6 , there are two avoidance grooves. The avoidance grooves include a first avoidance groove 31 and a second avoidance groove 32. The first avoidance groove 31 is set on the left or right side of the battery replacement battery 1, or two can be set at the same time (two are set in FIG6 ), and the second avoidance groove 32 is set between the left and right sides of the battery replacement battery 1.

[0062] 11 and 12 , the chassis of the vehicle includes a left battery-changing beam 41 and a right battery-changing beam 42 , wherein the left battery-changing beam 41 is provided with an escape space 43 for the passage of the engine exhaust pipe 44 . The escape space 43 may also be provided on the right battery-changing beam 42 .

[0063] The battery pack 45 is secured to the left and right battery-swap beams 41 and 42 via the battery-swap lock body 2. This battery pack configuration eliminates the need for a clearance slot for the exhaust pipe. This reduces the cost of new component manufacturing and design changes. Furthermore, the exhaust pipe is independently located from the battery pack, minimizing interference between assembly systems.

[0064] Furthermore, as shown in FIG1 , the range extender unit 5 further includes an engine 53 and a generator 54 ; the drive motor includes a front drive motor 61 and / or a rear drive motor 62 or a four-wheel drive motor;

[0065] The control unit 5 includes a motor controller 8 and a range extender controller (not marked, integrated with the engine or integrated with the motor controller or integrated with the control unit). The motor driver is connected to the drive motor and the battery replacement battery respectively. The range extender controller (not marked) is connected to the engine 53, the generator 54, and the battery replacement battery 1 respectively.

[0066] Example 2

[0067] As shown in Figure 7, the present invention discloses a refueling station for refueling the above-mentioned vehicles. The refueling station 7 is also provided with a refueling machine and a refueling gun 72 on the battery swap station 71, which is used to refuel the vehicle when the vehicle is refueling. The refueling station 7 is provided with a battery swap control unit, which includes a refueling calculation module, a battery swap settlement module, a cost summary output module, and a refueling mode selection module. At this stage, comprehensive refueling stations need to go to another place to continue refueling after charging. The entire refueling process is separated between charging and refueling, which is equivalent to paying twice, charging once and refueling once. It is cumbersome to use and the user experience is poor. In the refueling station of the present invention, battery swapping and refueling are completed in a centralized manner, and the user experience is better.

[0068] The battery swap control unit can include different parts, such as a refueling calculation module, a battery swap settlement module, a cost summary output module, and a refueling mode selection module. The refueling mode selection module is used to determine whether the vehicle's refueling is to be done by refueling or charging, or whether both refueling and charging are required; the refueling calculation module is used to calculate the amount of fuel and refueling costs when the vehicle is refueling; the battery swap settlement module is used to determine the cost of the vehicle's battery swap; and the cost summary output module can be used to summarize the costs of refueling and battery swapping for output or display.

[0069] Example 3

[0070] As shown in FIG8 , the present invention discloses an energy replenishment method, which is applied to the energy replenishment station 7 of the aforementioned embodiment. The energy replenishment method at least includes the following:

[0071] S1 performs an energy replenishment operation for the battery-swap extended-range electric vehicle in response to a consumer selecting an operation of battery swapping or refueling or both battery swapping and refueling; the energy replenishment operation is battery swapping or refueling or both battery swapping and refueling;

[0072] S11: The vehicle drives into the battery swap station of the energy recharging station and is limited to prevent movement. The battery swap platform on the battery swap station first removes the battery that needs to be replaced, and then sends the new battery to the bottom of the vehicle and installs it.

[0073] S12: After the vehicle enters the battery swap station of the charging station and is limited to prevent movement, the battery swap operation S11 is completed. If the consumer chooses to refuel at the same time, the staff will manually or automatically open the fuel cap through the machine and insert the fuel gun to prepare for refueling; then, refueling begins; the overall charging time is equal to the sum of the battery swap time + refueling time.

[0074] Or S11 and S12 are executed synchronously. At this time, the charging time is equal to either the battery replacement time or the refueling time. Synchronous execution can greatly improve the charging efficiency and reduce queuing congestion.

[0075] S2 obtains the replenishment result of the energy replenishment operation and processes the energy replenishment fee according to the replenishment result.

[0076] This step is the fee settlement step, in which the energy charging station 7 obtains the replenishment results of the energy replenishment operation after completing the energy replenishment operation, such as whether the battery replacement and refueling are completed, the parameters of the battery replacement, the amount of refueling operation, etc., and settles and determines the energy charging fee based on these replenishment results.

[0077] The refueling station is modified based on the existing public technology battery swap station. A refueling gun is installed next to the battery swap station, and the overall refueling system is incorporated into the settlement module of the entire battery swap system.

[0078] Example 4

[0079] As shown in Figures 9 and 10, a new type of energy replenishing station is provided with a standard battery replacement platform for at least two battery replacement systems on the battery replacement station 7 of the energy replenishing station, which is used to replace batteries for battery replacement vehicles with different battery replacement systems at the battery replacement station 96 of the same battery replacement station; the battery replacement system is not unified, which limits the practical application of the battery replacement technology route. Therefore, it is necessary to combine the battery replacement station with the gas station while allowing battery replacement vehicles with different battery replacement systems to also replace batteries at the same station, thereby improving the battery replacement utilization rate of the battery replacement station, reducing operating costs, and reducing the cost investment of enterprises in deploying battery replacement stations.

[0080] A conveying mechanism 95 is provided at the bottom of the battery exchange station 96. The conveying mechanism 95 has a battery conveyor belt 951. The conveying mechanism 95 is a guide rail or a conveyor belt, etc. A movable universal transport platform 9 is provided on the conveying mechanism 95; it is used to transport the first battery exchange standard platform 911 and the second battery exchange standard platform 921 of the at least two battery exchange systems to the battery exchange station 96. For example, the first standard battery exchange platform 911 is a private car battery exchange standard system, and the second battery exchange standard platform 921 is a commercial vehicle battery exchange standard system. In this way, vehicles of different standard systems can change batteries at the same battery exchange station; the two-way arrows in the figure represent the reciprocating conveying direction.

[0081] The conveying mechanism 95 is connected to the battery swap standard platform storage warehouse, which includes a warehouse 91 for the first battery swap standard platform and a warehouse 92 for the second battery swap standard. At least one battery swap standard platform is provided on the storage warehouse, and the battery swap standard platform includes at least a battery swap structure 98 and a lifting mechanism 99 for chassis battery swap; this is a general technology for chassis battery swap, and the present invention will no longer repeat each detailed component one by one.

[0082] The general battery swapping implementation methods for vehicles with different battery swapping systems are as follows:

[0083] The first step is to select a standard battery swap platform for different battery swap systems. After the vehicle stops at the battery swap station 96, the battery swap station identifies the vehicle type and determines whether it is an operating vehicle or a private car. Based on the identification result, the movable universal transport platform 9 transports one of the first battery swap standard platform 911 or the second battery swap standard platform 921 to the battery swap station 96 and limits it to prevent movement.

[0084] The second step is battery replacement. At this time, the battery replacement operation is performed according to the specific battery replacement steps of different battery replacement systems. For example, the operation of the battery replacement system for operating vehicles is as follows:

[0085] First remove the battery, and then transport the new battery from the battery warehouse (the battery warehouse 93 of the first battery exchange standard system and the battery warehouse 94 of the second battery exchange standard system) through a conveying mechanism (not shown in the prior art) to the top of the lifting mechanism 99 of the battery exchange standard platform. The lifting mechanism 99 lifts and supports the fully charged battery 97 to the bottom of the vehicle. The battery exchange mechanism 98 completes the locking operation of the fully charged battery 97, and the fully charged battery 97 is locked into the battery installation cavity 10 of the vehicle.

[0086] Removing the battery is the reverse operation of installing the battery, and the present invention will not describe it in detail.
