Description

Battery swapping methods at battery swapping stations

This application is a divisional application of a Chinese patent application with the filing date of November 30, 2017, the application number being 2017112442213, and the invention title being “Shuttle Battery Pack Replacement Equipment and Power Swapping Station Including the Same”.

Technical field

The invention relates to a power swapping method in a power swapping station.

Background technique

At present, vehicle exhaust emissions are still an important factor in environmental pollution. In order to control vehicle exhaust, people have developed natural vehicles, hydrogen fuel vehicles, solar vehicles and electric vehicles to replace fuel-based vehicles. Among them, the most promising application is electric vehicles. Current electric vehicles mainly include direct charging and quick-change types.

Quick-swap electric vehicles require a battery-swapping trolley to replace their batteries. The battery-swapping trolley includes a vehicle-carrying platform and battery-swapping equipment located on the vehicle-carrying platform. The existing power-swapping equipment's moving chassis and battery tray are connected through a scissor-type support. When the scissor-type support is not extended, its height is relatively high, causing the power-swapping equipment to be installed in a vehicle platform. The overall height of the battery swapping trolley is relatively high, which requires a deep pit on the battery swapping platform to allow the battery swapping trolley to enter the bottom of the car. This greatly increases the construction cost of the battery swapping station. Moreover, due to the need to set up pits, the battery swapping trolley raises the height of the battery swapping station. The overall height of the battery platform increases the height of the ramp connecting the battery exchange platform, which reduces the passability of driving vehicles.

Both the first driving part 160 and the second driving part 170 include a screw nut transmission mechanism and a rotary motor that drives the screw of the screw nut transmission mechanism to rotate, thereby realizing linear motion of the first motion frame 121 and the second motion frame 131 . Screw nut transmission mechanisms and rotating electrical machines have been widely used in the prior art, and will not be described in detail here. Of course, those skilled in the art can also use other devices such as linear motors as the first driving part 160 and the second driving part 170 .

The first driving part 160 , the second driving part 170 and the lifting driving unit 184 are all controlled by a control unit. The control unit may be a control device provided in the shuttle battery pack replacement device 100 , or may be a controller using the shuttle battery pack replacement device 100 . The battery pack replacement device 100 is the overall control device of the battery swap station.

When it is necessary to disassemble the battery of the vehicle, the shuttle battery pack replacement device 100 first moves to the bottom of the vehicle. The first driving part 160 and the second driving part 170 receive the instruction and cause the first movement frame 121 and the second movement frame 131 to first move laterally to a predetermined position, and then the lifting driving unit 184 receives the instruction and causes the lifting frame 106 to rise to a predetermined position. position. At this time, the first fork 122 forks the lock base for locking the battery pack on the vehicle, the second fork 134 forks the vehicle's battery, and the unlocking mechanism 123 unlocks the battery lock so that the battery is no longer locked to the vehicle. Then, The first moving frame 121 remains stationary, while the second moving frame 131 moves in a direction away from the first moving frame 121, so that the battery is separated from the vehicle. After the battery is separated from the vehicle, it falls on the tray 133, and then the lifting frame 106 moves downward. As the battery moves downward, the shuttle battery pack replacement device 100 drives away from the bottom of the vehicle with the removed battery.

When the battery of the vehicle needs to be installed, the shuttle battery pack replacement device 100 moves to the bottom of the vehicle with the fully charged battery. The first driving part 160 and the second driving part 170 receive instructions and cause the first movement frame 121 and the second movement frame 121 to move. The frame 131 first moves laterally to a predetermined position, and the lifting drive unit 184 receives the instruction and causes the lifting frame 106 to rise to the predetermined position. At this time, the first fork 122 forks the lock base for locking the battery pack on the vehicle, and the second fork 122 134 forks the fully charged battery, and then the first movement frame 121 remains stationary, while the second movement frame 131 moves toward the direction close to the first movement frame 121, so that the battery is fixed to the vehicle and the unlocking mechanism 123 locks the battery to the vehicle. on the vehicle.

As shown in Figure 13, the battery swap station includes: a charging room (not shown), a battery swap platform 190, a lifting mechanism 191 and a shuttle battery pack replacement device 100.

The lifting mechanism 191 is provided on the power exchange platform 190 and is used to lift the vehicle 200 on the power exchange platform 190 . The lifting mechanism 191 is generally a pillar for supporting the four wheels of the vehicle 200 . In Figure 13, the lifting mechanism 191 is in a raised state.

The shuttle battery pack replacement device 100 can travel between the battery replacement platform 190 and the charging room, and is used to transport the fully charged battery 210 in the charging room to the vehicle 200 or transport the battery 210 removed from the vehicle 200 to the charging room. to charge.

When the shuttle battery pack replacement device 100 is loaded with batteries 210 (whether they are batteries removed from the vehicle 200 or fully charged batteries) and needs to be entered and exited from the bottom of the vehicle 200 , the lifting mechanism 191 lifts the vehicle 200 upwards. , to allow the shuttle battery pack replacement device 100 to enter and exit the bottom of the vehicle 200 smoothly.

Since the shuttle battery pack replacement equipment 100 adopts a cam mechanism, its height is relatively low (the total height of the equipment is 175 mm), and the four cams 181 are lifted simultaneously by 80 mm, while the height of the bottom plate of the vehicle 200 from the ground is generally 190 mm. . After the vehicle 200 enters the battery swap platform 190, the shuttle battery pack replacement device 100 can directly enter the bottom of the vehicle 200, and the shuttle battery pack replacement device 100 is lifted 80 mm to lock or unlock the battery. After the battery is removed, the lifting mechanism 191 lifts the vehicle 200 by 200 mm to allow the shuttle battery pack replacement device 100 to remove the battery from the bottom of the vehicle 200 .

Since the overall height of the shuttle battery pack replacement device 100 is reduced, the battery swap platform 190 of the battery swap station does not need to be provided with a deeper pit to allow the shuttle battery pack replacement device 100 to enter the bottom of the vehicle 200. Therefore, the battery swap platform 190 The overall height of the battery exchange platform 190 is reduced, so that the height of the up ramp and down ramp to enter the power exchange platform 190 can be reduced to 230 mm (the original height is 480 mm), further reducing the difficulty of driving the vehicle 200. The lengths of the up ramps and down ramps are also reduced accordingly, from the original 7345 mm and 4545 mm to 4500 mm and 3000 mm, thereby reducing the construction cost of the power swap station.

Although specific embodiments of the present invention have been described above, those skilled in the art will understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
