Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle battery swapping, and particularly to a battery swapping and charging system for electric vehicles that can quickly disassemble and assemble standardized modular brick batteries. Background Art

[0002] Most of the battery packs of existing electric vehicles are designed, installed, and fixed according to the spatial dimensions of the vehicle chassis layout. The battery accounts for more than 50% of the cost of electric vehicles. The high battery price makes the overall cost of electric vehicles relatively high, which affects the large-scale and rapid popularization of electric vehicles. To solve this problem, many enterprises adopt a battery swapping mode in which the electric vehicle and the battery box are separated and the vehicle and battery are separated. The battery box is operated and managed by a third party, resulting in a significant reduction in the overall vehicle price. In the current vehicle-battery separation battery swapping mode, different manufacturers design and adapt different battery boxes according to different vehicle models. Since the battery boxes are non-standard designed according to different vehicle models, they cannot be standardized, mass-produced, and modularly replicated, making it difficult to promote across the industry. Moreover, they cannot be quickly disassembled and assembled, which is time-consuming and laborious. To solve the above problems, a battery swapping and charging system for electric vehicles that can quickly disassemble and assemble standardized modular brick batteries is designed.

The driver selects the vehicle model through the mobile terminal or the electronic control terminal prepared by the battery swapping station. The battery transportation robot module automatically matches the handling robot module and the empty battery transportation board according to the vehicle model instruction issued by the electronic control terminal. The driver drives the electric vehicle into the battery swapping lane at a fixed position. The staff controls the battery robot to drive towards the designated position of the battery swapping lane through the robot remote control for position alignment. Guided by the battery installation guide column, the top of the battery robot rises, driving the battery transportation board to move upward, so that the battery slot at the top of the battery transportation board is inserted and connected to the bottom of the standard module brick battery. The top of the battery robot continues to rise until the pressure sensor is set on the upper plane of each standardized module brick battery corresponding to the lower plane of the pressing beam to send a pressing signal and a wireless signal is sent through the corresponding sensing circuit attached to the BMS parallel control unit and displayed on the robot remote control. At this time, the staff controls the electric telescopic rod of the electric control battery compartment locking sub to retract through the robot remote control and the corresponding control circuit attached to the BMS parallel control unit, so that the battery compartment locking sub is separated and unlocked from the battery locking sub. The staff controls the battery robot to descend, disassemble the standard module brick battery and move it to the charging component, select the charging component corresponding to the vehicle model, and control the top of the battery robot to move upward so that the positive electrode socket and negative electrode socket of the standard module brick battery are connected to the charging positive electrode plug and charging negative electrode plug of the charging component. At this time, the staff controls the electric telescopic rod of the electric control charging rack locking sub of the charging component to extend, so that the electric control charging rack locking sub is clamped with the battery locking sub, and the standard module brick battery is fixed on the charging frame for charging;While one staff member disassembles the standardized modular brick battery, another staff member remotely controls the battery robot to move to the charging component where the fully charged standardized modular brick battery is stored, and performs the same operations as those for the standardized battery modular brick battery from which the battery compartment locking sub - assembly is removed. The fully charged standardized modular brick battery is taken out, and after being taken out, it is moved under the electric vehicle for position alignment. Guided by the battery installation guide posts, the top of the battery robot rises, driving the battery transport plate upward, so that the positive socket, negative socket, and low - voltage signal socket of the standardized modular brick battery are respectively connected to the positive plug, negative plug, and low - voltage signal plug. The top of the battery robot continues to rise until the lower plane of the pressing beam corresponds to the upper plane of each standardized modular brick battery, and a pressure sensor emits a pressing signal and a wireless signal is sent through the corresponding sensing circuit attached to the BMS parallel control unit and displayed on the robot remote control. At this time, the staff member controls the electric telescopic rod of the electric control battery compartment locking sub - assembly to extend through the robot remote control and the corresponding control circuit attached to the BMS parallel control unit, so that the battery compartment locking sub - assembly is clamped and locked with the battery locking sub - assembly. The standardized modular brick battery is fixedly installed on the standardized frame - type battery compartment through the battery compartment locking sub - assembly and the battery locking sub - assembly to supply power to the electric vehicle;

[0064] Among them, if the unmanned battery replacement application of the unmanned battery replacement station is to be realized, it is necessary to control the charging robot to implement the automatic route planning setting and automatic control function in the prior art. Through the preset program, the above - mentioned manual process operations are realized through automatic control, and then the battery replacement function is realized.

[0065] As Figure 14-15 shown, in order to meet the special needs of the skate - type low - floor chassis electric vehicle, the present invention specially designs the vehicle electric lift 20. Among them, the vehicle electric lift 20 adopts the same technology as the battery robot 11. After the skate - type low - floor electric vehicle 22 parks at the preset battery replacement position, the staff member remotely controls the open ends of the four vehicle electric lifts 20 to insert into the four tires from the side, and then controls the vehicle electric lift 20 to lift, lifting the vehicle to the set height and locking it. Then the battery transport robot module 21 can enter from the side under the standardized frame battery compartment and separate, disassemble, or clamp and lock the standardized modular brick battery in the standardized frame battery compartment in the same way as above.
