Description

Technical Field

[0001] The present invention relates to the field of vehicle battery replacement technology, and in particular, to a vehicle battery replacement method and system. Background Art

[0002] With the rapid development of science and technology, new energy vehicles are gradually replacing traditional fuel vehicles with their environmental protection, fast power response, low noise, light vibration, and relatively low maintenance costs. When users consider whether to buy new energy vehicles, their main concerns usually include short driving range and long charging time. Battery swap stations can effectively solve these two problems. New energy vehicle battery swap stations use a fast battery swap mode, which can complete battery replacement in just a few minutes, greatly saving charging time. At the same time, battery swap stations generally have a high degree of automation and can be unmanned, providing convenient services for car owners.

[0003] At present, due to the limitation of charger power, battery swap stations usually equip each charging station with a charger. When a vehicle comes to swap batteries, it is necessary to ensure that there is at least one charging station in the station without a battery to place the battery removed from the vehicle, and then install the battery in another charging station on the vehicle. This will cause a charger to be idle for a long time, resulting in unnecessary waste of resources. In addition, during peak hours, due to the large number of vehicles swapping batteries, the waiting time may be long and the efficiency of the battery swap station is low. Summary of the invention

[0022] In some embodiments, the vehicle battery replacement method further includes:

[0023] Step S151, based on the presence of a second vehicle in the battery swapping area after the first vehicle leaves the battery swapping area, obtaining the power of the charged battery in the priority charging station;

[0043] This embodiment discloses a method for replacing a battery in a vehicle 40, such as Figure 1 As shown, it may include:

[0044] Step S11, based on the first vehicle arriving at the battery swapping area, the battery swapping robot 30 moves the first low-power battery on the first vehicle to the turnover charging station 23;

[0045] Step S12, based on moving the first low-power battery to the turnover charging station 23, disconnecting the electrical connection between the priority charging station 21 and the charger 10 corresponding to the priority charging station 21, and connecting the turnover charging station 23 to the charger 10 corresponding to the priority charging station 21;

[0046] Step S13, based on the electrical connection between the priority charging station 21 and the charger 10 corresponding to the priority charging station 21 being cut off, the battery swapping robot 30 moves the charged battery of the priority charging station 21 to the first vehicle; wherein, the priority charging station 21 is closer to the first vehicle in the battery swapping area than the ordinary charging station 22; and the turnover charging station 23 is closer to the first vehicle in the battery swapping area than the ordinary charging station 22.

[0047] In this embodiment, new energy vehicles have the advantages of being environmentally friendly and having low maintenance costs, but they usually have long charging times and short driving ranges. Battery swap stations can effectively solve these two problems. Battery swap stations are usually equipped with chargers 10 at charging stations. The batteries are removed from the vehicle and then installed in the charging stations on the vehicle 40. The battery swap system of the vehicle 40 may include a charger 10, a charging station 20, a battery swap robot 30, and a vehicle 40. Figure 2 As shown, the charging station 20 may include a priority charging station 21, multiple ordinary charging stations 22, and a turnover charging station 23. Each ordinary charging station 22 can be electrically connected to a charger 10, and a priority charging station 21 can be electrically connected to a charger 10. The charger 10 corresponding to a priority charging station 21 can be electrically connected to a turnover charging station 23. A priority charging station 21 and a turnover charging station 23 can be connected to a charger 10 at the same time. Due to the power limitation of the charger 10, two charging stations cannot be charged at the same time. Therefore, when the priority charging station 21 is charged, the turnover charging station 23 is powered off. When the turnover charging station 23 is powered on, the priority charging station 21 is powered off. As shown Figure 3 As shown, the vehicle 40 may include a vehicle body 41 and a battery replacement battery 42. The battery replacement battery 42 may be used to provide power to the vehicle body 41, and the battery replacement battery 42 may be detachably connected to the vehicle body 41, so that the battery replacement battery 42 is convenient to replace.

[0048] like Figure 1 As shown, the battery replacement method for vehicle 40 may include steps S11 to S13, and the steps will be described in detail below.

[0049] In step S11, since the battery replacement system of vehicle 40 cannot replace batteries for multiple vehicles 40 at the same time, when multiple vehicles need to replace batteries, vehicles 40 can queue up in order. The first vehicle in the queue can be the first vehicle, and the vehicle behind the first vehicle is the second vehicle. The battery replacement system of vehicle 40 can recognize that after the first vehicle enters the battery replacement area, the turnover charging station 23 is idle. After receiving the battery replacement signal from the battery replacement system of vehicle 40, the battery replacement robot 30 can move the first low-power battery on the first vehicle to the turnover charging station 23, and the turnover charging station 23 can be closer to the vehicle 40 than the ordinary charging station 22. In this way, the first low-power battery can be charged faster, thereby improving the battery replacement efficiency, and it is also convenient for the first vehicle to leave space to replace the charged battery.

[0050] In step S12, when the first low-power battery is moved to the turnover charging station 23, the priority charging station 21 can be electrically disconnected from the charger 10 corresponding to the priority charging station 21. The turnover charging station 23 can be electrically connected to the charger 10 corresponding to the priority charging station 21 to ensure that the charger 10 can be efficiently used to charge the battery. The first low-power battery has a lower power than the charged battery in the priority charging station 21 and therefore has a higher charging efficiency. By dynamically adjusting the connection between the charging station and the charger 10, the use efficiency of the charger 10 can be maximized.

[0051] In step S13, after the electrical connection between the priority charging station 21 and the charger 10 corresponding to the priority charging station 21 is cut off, the battery-swapping robot 30 can move the charged battery of the priority charging station 21 to the first vehicle. This can prevent sparks from being generated during battery replacement, which can easily cause electric shock to the charging connector. The contact resistance at the contact point of the charging connector will increase during the next charging, which can easily cause heat and lead to safety hazards. This can improve safety and increase the life of the charging cable. The priority charging station 21 can be closer to the first vehicle in the battery replacement area than the ordinary charging station 22, so that the first vehicle can be replaced more quickly and the battery replacement efficiency can be improved. The turnover charging station 23 can be closer to the first vehicle in the battery replacement area than the ordinary charging station 22. This can ensure that the distance between the turnover charging station 23 and the first vehicle is short, the working path of the battery replacement robot 30 is short, and the working efficiency of the battery replacement robot 30 is improved.

[0052] In some embodiments, the vehicle 40 battery replacement method further includes:

[0053] Step S141, based on moving the charged battery of the priority charging station 21 to the first vehicle, obtaining the common charging station 22 with the highest power of the charged battery among the common charging stations 22;

[0054] Step S142 , based on the common charging station 22 having the highest power level of the charged battery, the charged battery with the highest power level among the charged batteries is moved to the priority charging station 21 .

[0055] In this embodiment, the battery replacement method for vehicle 40 may further include steps S141 to S142, and each step may be described in detail below.

[0056] In step S141, when the charged battery of the priority charging station 21 is moved to the first car, the ordinary charging station 22 with the highest power among the charged batteries in the ordinary charging station 22 can be obtained. Charging resources can be managed more intelligently. In this way, in the subsequent process, the battery with higher power can continue to be supplied to the second car. The battery with low power can continue to be charged at the ordinary charging station 22, and the charging speed is faster than the battery with higher power. Ensure that all batteries can be used reasonably, thereby improving the efficiency of the entire vehicle 40 battery replacement system.

[0057] In step S142, when the common charging station 22 with the highest power of the charged battery is obtained, the charged battery with the highest power among the charged batteries can be moved to the priority charging station 21. In this way, for the vehicle 40 and the owner who need to charge, when the charged battery of the priority charging station 21 is replaced, a battery with a higher power can be obtained, and the priority charging station 21 is closer to the vehicle 40 than the common charging station 22, which helps to reduce waiting time and improve battery replacement efficiency.

[0058] In some embodiments, the vehicle 40 battery replacement method further includes:

[0059] Step S143, based on the fact that the charged battery with the highest power among the charged batteries moves to the priority charging station 21, and there is no first vehicle in the battery swapping area, a vehicle 40 in the battery swapping area is obtained;

[0060] Step S144, based on the fact that there is no vehicle 40 in the battery exchange area, the first low-power battery in the turnover charging station 23 is moved to the idle ordinary charging station 22.

[0061] In this embodiment, the battery replacement method for vehicle 40 may further include steps S143 to S144, and each step may be described in detail below.

[0062] In step S143, after the charged battery with the highest power among the charged batteries is moved to the priority charging station 21, and the first vehicle has left the battery swap area, it is possible to identify whether there are any remaining queued vehicles 40 in the battery swap area. This is convenient in the subsequent process, by judging whether there are any remaining queued vehicles 40 in the battery swap area, the position of the first low-power battery in the turnover charging station 23 can be determined, and whether the charging station connected to the charger 10 corresponding to the priority charging station 21 is the priority charging station 21 or the turnover charging station 23.

[0063] Step S144, if it is detected that there is no vehicle 40 in the battery exchange area. At this time, if there is no vehicle 40 waiting for battery exchange, the first low-power battery in the turnover charging station 23 can be moved to the idle ordinary charging station 22. In this way, the charger 10 connected to the idle ordinary charging station 22 does not need to be idle for a long time, and the first low-power battery can be charged. At this time, the first rechargeable battery with low power can be charged faster and more efficiently than the battery with high power. At this time, the turnover charging station 23 is idle. Later, when the battery in the priority charging station 21 is not fully charged, a car needs to be replaced, and the low-power battery can be conveniently placed in the turnover charging station 23.

[0064] In some embodiments, the vehicle 40 battery replacement method further includes:

[0065] Step S145, based on the first low-power battery in the turnover charging station 23 moving to the idle common charging station 22, the power of the charged battery in the priority charging station 21 is obtained;

[0066] Step S146 , based on the fact that the charged battery in the priority charging station 21 is a fully charged battery, the charged battery in the priority charging station 21 is moved to the turnover charging station 23 .

[0067] In this embodiment, the battery replacement method for vehicle 40 may further include steps S145 to S146, and each step may be described in detail below.

[0068] Step S145, after the first low-power battery in the turnover charging station 23 is moved to the idle common charging station 22, the power of the battery after charging in the priority charging station 21 can be obtained. By understanding and judging the power of the battery after charging in the priority charging station 21, it can be timely determined whether to move the battery out of the priority charging station 21 in the future.

[0069] Step S146, if the obtained charged battery in the priority charging station 21 is a fully charged battery, the charged battery in the priority charging station 21 can be moved to the turnover charging station 23. In this way, the fully charged battery can be conveniently replaced with the car when waiting for the car to come next time, and the low-charged battery in the car can be replaced with the priority charging station 21, and the priority charging station 21 can be closer to the charger 10 corresponding to the priority charging station 21 than the turnover charging station 23, and the charging loss is smaller, which is conducive to improving the charging efficiency.

[0070] In some embodiments, the vehicle 40 battery replacement method further includes:

[0071] Step S147, based on the charged battery in the priority charging station 21 moving to the turnover charging station 23, the electrical connection between the charger 10 corresponding to the priority charging station 21 and the turnover charging station 23 is disconnected, and the charger 10 corresponding to the priority charging station 21 is electrically connected to the priority charging station 21.

[0072] In this embodiment, the battery replacement method of the vehicle 40 may further include step S147:

[0073] In step S147, after the charged battery in the priority charging station 21 is moved to the turnover charging station 23, the electrical connection between the charger 10 corresponding to the priority charging station 21 and the turnover charging station 23 can be disconnected. The battery in the turnover charging station 23 is fully charged and does not need to be charged at this time, so the electrical connection can be disconnected. And the charger 10 corresponding to the priority charging station 21 can be electrically connected to the priority charging station 21, so that when a vehicle 40 comes later, the low-power battery in the vehicle 40 can be placed in the priority charging station 21. Since the low-power battery has less power, it can be charged very quickly, which is conducive to improving the charging efficiency. Moreover, the priority charging station 21 can be closer to the charger 10 corresponding to the turnover charging station 23 than the priority charging station 21, and the charging loss is smaller, which is conducive to improving the charging efficiency.

[0074] In some embodiments, the vehicle 40 battery replacement method further includes:

[0075] Step S148, based on the fact that the charged battery in the priority charging station 21 is not fully charged, the electrical connection between the charger 10 corresponding to the priority charging station 21 and the turnover charging station 23 is disconnected, and the charger 10 corresponding to the priority charging station 21 is electrically connected to the priority charging station 21.

[0076] In this embodiment, the battery replacement method of the vehicle 40 may further include step S148:

[0077] In step S148, if the charged battery in the priority charging station 21 obtained is a partially charged battery, the electrical connection between the charger 10 corresponding to the priority charging station 21 and the turnover charging station 23 can be disconnected, so that when a subsequent vehicle 40 comes, the low-power battery in the subsequent vehicle 40 can be placed in the turnover charging station 23 for charging. Since the low-power battery has a small amount of power, it can be charged very quickly, thereby improving the charging efficiency. And the charger 10 corresponding to the priority charging station 21 can be electrically connected to the priority charging station 21, because the battery in the priority charging station 21 is a partially charged battery, and the electrical connection can be maintained to allow the partially charged battery to continue charging to supply the vehicle 40 that needs to be replaced. Moreover, the priority charging station 21 can be closer to the charger 10 corresponding to the priority charging station 21 than the turnover charging station 23, and the charging loss is smaller, which is conducive to improving the charging efficiency.

[0078] In some embodiments, the vehicle 40 battery replacement method further includes:

[0079] Step S151, based on the presence of a second vehicle in the battery swapping area after the first vehicle leaves the battery swapping area, obtaining the power of the battery after charging in the priority charging station 21;

[0080] Step S152, based on the fact that the power of the battery after charging in the priority charging station 21 is less than the first set value, the charger 10 corresponding to the priority charging station 21 is electrically disconnected from the turnover charging station 23, and the charger 10 corresponding to the priority charging station 21 is electrically connected to the priority charging station 21;

[0081] Step S153, based on the fact that the charger 10 corresponding to the priority charging station 21 is electrically disconnected from the turnover charging station 23, the second low-power battery on the second vehicle is moved to the idle common charging station 22;

[0082] Step S154, based on the second low-power battery being moved to the idle common charging station 22, the charged battery in the priority charging station 21 is moved to the second vehicle.

[0083] In this embodiment, the battery replacement method for vehicle 40 may further include steps S151 to S154, and each step may be described in detail below.

[0084] Step S151, when the first car leaves the battery swap area and there is a second car in the battery swap area, the power of the battery after charging in the priority charging station 21 can be obtained. Subsequent operations can be performed by judging whether the battery after charging reaches a set value.

[0085] Step S152, if the power of the battery after charging in the priority charging station 21 is less than the first set value (the first set value can be 90% of the battery power), the electrical connection between the charger 10 corresponding to the priority charging station 21 and the turnover charging station 23 can be disconnected, and the charger 10 corresponding to the priority charging station 21 can be electrically connected to the priority charging station 21. Because the power of the battery in the priority charging station 21 is less than the first set value at this time, the battery charging speed still has room to increase. At this time, allocating electricity to the priority charging station 21 can improve the charging efficiency. Because the priority charging station 21 can be closer to the charger 10 corresponding to the priority charging station 21 than the turnover charging station 23, the charging loss is smaller.

[0086] Step S153, after the charger 10 corresponding to the priority charging station 21 is electrically disconnected from the turnover charging station 23, the battery swap robot 30 can move the second low-power battery on the second vehicle to the idle ordinary charging station 22. Because the charger 10 corresponding to the priority charging station 21 is electrically disconnected from the turnover charging station 23 at this time, an instruction can be given to the battery swap robot 30 to start the battery swap operation. During this period of time, the charger 10 corresponding to the priority charging station 21 can charge the rechargeable battery in the priority charging station 21.

[0087] Step S154, during the time when the battery swap robot 30 moves the second low-power battery to the idle ordinary charging station 22, the charger 10 corresponding to the priority charging station 21 is electrically connected to the priority charging station 21. If the power of the battery in the priority charging station 21 is less than the first set value based on the factory setting of the battery charging, the charging rate is faster. During this period, the power of the battery in the priority charging station 21 can be increased faster, so that the driver can get as much mileage as possible in a single battery swap. At this time, the battery swap robot 30 can move the charged battery in the priority charging station 21 to the second car.

[0088] In some embodiments, the vehicle 40 battery replacement method further includes:

[0089] In step S155 , based on the charged battery in the priority charging station 21 leaving the priority charging station 21 , the charger 10 corresponding to the priority charging station 21 is electrically disconnected from the priority charging station 21 , and the charger 10 corresponding to the priority charging station 21 is electrically connected to the turnover charging station 23 .

[0090] In this embodiment, the battery replacement method of the vehicle 40 may further include step S155:

[0091] Step S155, when the charged battery in the priority charging station 21 leaves the priority charging station 21, there is no battery in the priority charging station 21, and the charger 10 corresponding to the priority charging station 21 can be disconnected from the electrical connection with the priority charging station 21, and the charger 10 corresponding to the priority charging station 21 can be electrically connected to the turnover charging station 23. In this way, the first low-power battery in the turnover charging station 23 can be charged, and the charging rate is fast at this time, and the next vehicle 40 that needs battery replacement can be quickly supplied for battery replacement, which is conducive to improving the battery replacement efficiency of the battery replacement station.

[0092] In some embodiments, the vehicle 40 battery replacement method further includes:

[0093] Step S1521, based on the fact that the power of the battery after charging in the priority charging station 21 is greater than or equal to the first set value, the second low-power battery is moved to the idle common charging station 22;

[0094] Step S1522, based on the second low-power battery being moved to the idle common charging station 22, the charged battery in the priority charging station 21 is moved to the second vehicle.

[0095] In this embodiment, step S152 may also include step S1521 to step S1522, and each step may be described in detail below.

[0096] Step S1521, if the power of the battery after charging in the priority charging station 21 is greater than or equal to the first set value (the first set value can be 90% of the battery power), the power has reached the first set value, and the charging speed is slow and inefficient, so the power resources can be allocated to the first low-power battery in the turnover charging station 23. The first low-power battery has a low power, and its own power is low during charging. The charging speed is fast based on the factory settings of the battery charging. When a car comes, the charged battery with a higher power can be quickly replaced in the car, which can improve the efficiency of battery replacement at the battery replacement station. At this time, the battery replacement robot 30 can move the second low-power battery to the idle ordinary charging station 22, and the ordinary charging station 22 can charge the second low-power battery.

[0097] Step S1522, after the battery swap robot 30 moves the second low-power battery to the idle ordinary charging station 22, an instruction can be given to the battery swap robot 30 to move the charged battery in the priority charging station 21 to the second car. In this way, the power of the charged battery in the priority charging station 21 is greater than or equal to the first set value, and the power is high enough to be transferred to the second car. The priority charging station 21 is closer to the car than the ordinary charging station 22, and the working path of the battery swap robot 30 is short, which improves the working efficiency of the battery swap robot 30.

[0098] In this embodiment, a vehicle 40 battery replacement system is provided, which can be applied to any of the vehicle 40 battery replacement methods in the above embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the battery replacement system of vehicle 40 includes:

[0099] Vehicle 40, vehicle 40 includes a vehicle body 41, a battery replacement battery 42; the vehicle body 41 is electrically connected to the battery replacement battery 42; the vehicle body 41 and the battery replacement battery 42 are detachably connected; a charger 10; a charging stand 20, the charging stand 20 includes a priority charging station 21, multiple ordinary charging stations 22, and a turnover charging station 23; a priority charging station 21 is electrically connected to a charger 10; each ordinary charging station 22 is electrically connected to a charger 10; the charger 10 corresponding to the priority charging station 21 is electrically connected to the turnover charging station 23; The charging station 23 is electrically connected; the priority charging station 21 is closer to the vehicle 40 in the battery swapping area than the ordinary charging station 22; the turnover charging station 23 is closer to the vehicle 40 in the battery swapping area than the ordinary charging station 22; the battery swapping robot 30, the battery swapping robot 30 includes a machine body 31, a walking part 32, and a grabbing part 33; the walking part 32 is detachably connected to the machine body 31; the walking part 32 provides power for the movement of the machine body 31; the grabbing part 33 is detachably connected to the machine body 31; the grabbing part 33 grabs the battery swapping battery 42.

[0100] In this embodiment, if Figure 2 , Figure 3 , Figure 4 As shown, the vehicle 40 battery replacement system may include:

[0101] Vehicle 40, charger 10, charging station 20, battery exchange robot 30. Vehicle 40 may include a vehicle body 41 and a battery exchange battery 42. The vehicle body 41 may be electrically connected to the battery exchange battery 42, so that the battery exchange battery 42 can provide power to the vehicle body 41. The vehicle body 41 may be detachably connected to the battery exchange battery 42, and the detachable connection allows the battery to be replaced in time when the battery performance is poor, thereby ensuring the performance and range of the vehicle 40. The charging station 20 may include a priority charging station 21, multiple ordinary charging stations 22, and a turnover charging station 23. A priority charging station 21 may be electrically connected to a charger 10, and each ordinary charging station 22 may be electrically connected to a charger 10. In this way, the charger 10 can supply power to the priority charging station 21 and the ordinary charging station 22 for the vehicle 40 to exchange power. The charger 10 corresponding to a priority charging station 21 may be electrically connected to a turnover charging station 23. In this way, the charging resources of the charger 10 can be conveniently and reasonably allocated. During the charging process of the turnover charging station 23 and the battery swap station, the charger 10 is always used for power supply and does not need to be idle. When charging the priority charging station 21, the turnover charging station 23 is powered off. When the turnover charging station 23 is powered on, the priority charging station 21 is powered off. The priority charging station 21 can be closer to the vehicle 40 in the battery swap area than the ordinary charging station 22, and the turnover charging station 23 can be closer to the vehicle 40 in the battery swap area than the ordinary charging station 22. In this way, when replacing the battery of the vehicle 40, the battery swap robot 30 can take out the battery from the priority charging station 21 or the ordinary charging station 22 for replacement. The working path is shorter than when taking out the battery from the ordinary charging station 22 for replacement, which saves more time and can improve the battery swap efficiency. The battery swap robot 30 may include a machine body 31, a walking part 32, and a grabbing part 33. The walking part 32 can be detachably connected to the machine body 31. When the walking part 32 fails or needs maintenance, the detachable connection allows technicians to easily remove and reinstall the walking part 32, which can simplify the maintenance process and reduce maintenance costs. The walking part 32 can provide power for the movement of the machine body 31, so that the robot can move autonomously in different environments. This enables the robot to reach designated locations and perform various tasks as needed. The robot can reach the working area quickly and accurately, improving the robot's work efficiency. The gripping part 33 can be detachably connected to the machine body 31. This connection method makes it unnecessary to replace the robot as a whole when a problem occurs with the gripping part 33, thereby reducing maintenance costs. The gripping part 33 can grab the battery replacement battery 42. This makes it convenient for the battery replacement robot 30 to easily replace batteries for vehicles 40 that need battery replacement.
