TECHNICAL FIELD

[0002] The battery box is the power source of the new energy vehicle, and its product quality is crucial. After the battery box is assembled and discharged on the production line, it needs to be charged and discharged for testing to verify whether the battery box meets the design specifications. To test the battery box, the power capacity of the factory building needs to meet the 500KW power requirement at the test station. When the factory building is temporarily rented and the power capacity of the factory building cannot meet the power requirement, if the power capacity is expanded, a large amount of money needs to be invested, and there are problems of long cycle, slow approval, and short rental period.

[0046] Many specific details are set forth in the following description to provide a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this specification. Therefore, this specification is not limited to the specific implementations disclosed below.

[0049] Current testing methods have stringent requirements for charging and discharging functions and capacity testing of high-capacity battery systems. They require corresponding power capacity to support the continuous operation of high-power equipment, and require the purchase of expensive and large charging and discharging cabinets. The equipment has limitations such as large footprint, inability to move quickly, and the need for appropriate cable laying layout. Each discharge is converted into an ineffective electronic load and released through the charging cabinet, resulting in serious economic waste.

[0050] The purpose of the embodiments in this specification is to provide a portable charge / discharge testing and power replenishment solution under specific conditions.

[0051] This specification provides a battery testing method, and also relates to a battery testing system, a computing device, a computer-readable storage medium, and a computer program, which are described in detail in the following embodiments.

[0052] Figure 1 A flowchart of a battery testing method according to an embodiment of this specification is shown. The battery testing method is applied to a battery testing system, which includes a charge / discharge integrated machine, a battery bracket, a test battery box, a test matching battery box, and a client. The battery bracket is provided with a charge / discharge interface, the test battery box is placed on the battery bracket and electrically connected to the charge / discharge interface, and the test battery box is communicatively connected to the client. The battery testing method specifically includes the following steps.

[0053] Step 102: When the client receives the battery test command, control the charging and discharging interface of the battery bracket to connect with the charging and discharging machine, and control the charging and discharging machine to connect with the test battery box.

[0054] A schematic diagram of a battery testing system provided in the embodiments of this specification is shown below. Figure 2 As shown, the battery testing system includes a charge / discharge integrated machine, a battery bracket, a test battery box, a battery box bracket, a test matching battery box, and a client. The test battery box is communicatively connected to the client.

[0055] In practical applications, the client is a smart terminal.

[0056] A schematic diagram of a battery holder provided in the embodiments of this specification is shown below. Figure 3 As shown, the battery bracket is equipped with a battery positioning seat, a charging interface, and a discharging interface. When the test battery box is placed on the battery bracket, the battery positioning seat and the test battery box are in a limiting fit, and the charging interface and the discharging interface are electrically connected to the test battery box respectively. The battery box bracket is equipped with a test matching battery box. The charging and discharging machine has several plugs, some of which are used to be detachably connected to the charging interface or the discharging interface, and some of which are used to be electrically connected to the test matching battery box.

[0057] Specifically, when the client receives a battery test command, it needs to connect the charging and discharging interface of the battery holder to the charging and discharging unit, and connect the charging and discharging unit to the test battery box, so as to perform charging and discharging tests on the test battery box through the charging and discharging unit and the test battery box.

[0058] In the embodiments of this specification, when the test battery box is charged or discharged using the above-described battery testing system, the electrical energy between the test battery box and the test battery box can be transferred, thereby reducing energy waste and improving energy utilization.

[0059] In practical applications, the test battery box can be a larger energy storage battery, for example, a specially manufactured large-size battery box, or a reused energy storage battery box used in heavy-duty trucks. The test battery box can include a frame and multiple battery packs housed within the frame. This test battery box can be a new battery box or an old one, as long as the stored energy meets the charge-discharge test requirements.

[0060] In one optional embodiment, the charging and discharging unit has a plurality of charging guns;

[0061] Accordingly, the control of the charging / discharging interface of the battery holder is connected to the integrated charging / discharging machine, and the control of the integrated charging / discharging machine is connected to the test battery box, including:

[0062] The control section's insertion gun is detachably connected to the charging / discharging interface, and the control section's insertion gun is detachably connected to the test-fit battery box.

[0063] Specifically, the charging and discharging unit is equipped with at least two charging guns. In this embodiment of the specification, in order to enable the charging and discharging test of the test battery box using the battery testing system, some of the charging and discharging guns of the charging and discharging unit need to be detachably connected to the charging and discharging interface, and some of the charging and discharging guns need to be detachably connected to the test battery box to establish a physical connection, i.e. an electrical connection, between the charging and discharging unit and the battery bracket, and between the charging and discharging unit and the test battery box.

[0064] In one alternative embodiment, a charging interface is provided on the battery holder;

[0065] Accordingly, the step of controlling the charging / discharging interface of the battery holder to connect with the charging / discharging integrated machine when the client receives a battery test command includes:

[0066] When the client receives a battery charging test command, it controls the charging interface of the battery holder to connect with the charging and discharging machine.

[0067] Specifically, as mentioned above, the battery testing system can perform charging or discharging tests on the test battery box. The battery bracket is equipped with a charging interface. When the client receives a battery charging test command, it needs to control the charging interface to connect with the charging and discharging machine. That is, it controls the charging and discharging machine's plug to connect with the charging interface so that the electrical energy of the test battery box can be transferred to the test battery box through the plug to perform charging tests on the test battery box.

[0068] In one alternative embodiment, a discharge port is provided on the battery holder;

[0069] Accordingly, the step of controlling the charging / discharging interface of the battery holder to connect with the charging / discharging integrated machine when the client receives a battery test command includes:

[0070] When the client receives a battery discharge test command, it controls the discharge interface of the battery holder to connect with the charging and discharging machine.

[0071] Specifically, as mentioned above, the battery testing system can perform charging or discharging tests on the test battery box. The battery bracket is equipped with a discharge interface. When the client receives a battery discharge test command, it needs to control the discharge interface to connect with the charging and discharging machine. That is, it controls the charging and discharging machine's plug to connect with the discharge interface so that the electrical energy of the test battery box can be transferred to the test battery box through the plug to perform a discharge test on the test battery box.

[0072] In one optional embodiment, the charge-discharge integrated machine is communicatively connected to both the test battery box and the test-matching battery box.

[0073] Accordingly, when the client receives a battery test command, controlling the charging / discharging interface of the battery holder to connect with the integrated charging / discharging machine, and controlling the integrated charging / discharging machine to connect with the test battery box, includes:

[0074] When the client receives a battery discharge test command, it controls the relay in the discharge circuit inside the test battery box to close based on the battery discharge test command, so as to control the discharge interface of the battery bracket to connect with the charging and discharging machine.

[0075] The charging and discharging unit sends the charging command issued by the test battery box to the test matching battery box, and controls the relay in the charging circuit of the test matching battery box to close based on the charging command, so as to control the connection between the charging and discharging unit and the test matching battery box.

[0076] Specifically, the connection between the integrated charge / discharge machine and the charge / discharge interface and the test battery box mentioned in the aforementioned embodiments, or the connection between the charging / discharge machine's charging / discharge gun and the charge / discharge interface and the test battery box, all refer to physical connections. However, in the embodiments of this specification, merely establishing such physical connections is insufficient to enable the battery testing system to perform charge / discharge tests on the test battery box. This is because the test battery box and the test battery box contain charging circuits (charging loops) and discharging circuits (discharging loops). The relays in both the charging and discharging circuits are in an open state before the test begins. Therefore, it is necessary to close the relays in the control circuit to truly connect the integrated charge / discharge machine to the charge / discharge interface and the test battery box.

[0077] Based on this, it is necessary to first establish a communication connection between the charging and discharging unit and the test battery box, and then establish a communication connection between the charging and discharging unit and the test battery box. When the client receives the battery discharge test command, it wakes up the battery management unit of the test battery box based on the battery discharge test command, so as to control the relay in the discharge circuit in the battery box to close through the battery management unit, thereby realizing the connection between the discharge interface of the battery bracket and the charging and discharging unit, that is, the charging and discharging unit's plug.

[0078] Furthermore, in addition to controlling the closure of the relays in its discharge circuit, the test battery box can also generate a charging command and send the command to the integrated charge-discharge unit. The integrated charge-discharge unit then sends the charging command to the test battery box, thereby waking up the battery management unit of the test battery box. The battery management unit then controls the closure of the relays in the charging circuit of the test battery box, thus connecting the discharge unit (i.e., the charging-discharge unit's plug) to the test battery box.

[0079] In addition, when the client receives a battery charging test command, it wakes up the battery management unit of the test battery box based on the battery charging test command, so as to control the relay in the charging circuit in the battery box to close, thereby connecting the charging interface of the battery bracket to the charging and discharging machine, i.e., the charging and discharging machine's plug.

[0080] Furthermore, in addition to controlling the closure of the relays in its charging circuit, the test battery box can also generate a discharge command and send the command to the charge-discharge integrated machine. The charge-discharge integrated machine then sends the discharge command to the test battery box, thereby waking up the battery management unit of the test battery box based on the discharge command. The battery management unit then controls the closure of the relays in the discharge circuit of the test battery box, thus connecting the discharge integrated machine (i.e., the charging-discharge integrated machine's plug-in) to the test battery box.

[0081] Step 104: Perform a charge and discharge test on the test battery box using the aforementioned test method.

[0082] Specifically, after connecting the charging or discharging interface of the control battery holder to the integrated charge / discharge machine, and connecting the integrated charge / discharge machine to the test battery box, the test battery box can be charged by transferring the electrical energy from the test battery box to the test battery box through the integrated charge / discharge machine, or discharged by transferring the electrical energy released by the test battery box to the test battery box through the integrated charge / discharge machine.

[0083] In one optional implementation, the step of performing a charge-discharge test on the test battery box using the test kit includes:

[0084] The charging and discharging unit charges the test battery box with electrical energy from the test battery box, thereby performing a charging test on the test battery box.

[0085] Specifically, a charging interface is set on the battery bracket, and the client receives the battery charging test command and controls the charging interface of the battery bracket to connect with the charging and discharging unit. Then, the charging and discharging unit transmits the power of the test battery box to the test battery box to realize the charging test of the test battery box.

[0086] Alternatively, the step of performing a charge-discharge test on the test battery box using the aforementioned test method includes:

[0087] The charging and discharging unit releases the electrical energy in the test battery box and charges the test battery box with the released electrical energy to perform a discharge test on the test battery box.

[0088] Specifically, a discharge interface is set on the battery bracket, and the client receives the battery discharge test command and controls the discharge interface of the battery bracket to connect with the charging and discharging unit. Then, the discharge test of the test battery box is achieved by transmitting the electrical energy released by the test battery box to the test battery box through the charging and discharging unit.

[0089] In one alternative implementation, the charging and discharging machine has several charging guns, and the charging guns include a power-taking gun and a power-discharging gun.

[0090] Accordingly, the charge-discharge test of the test battery box using the test and the battery box includes:

[0091] Connect the power-taking gun of the integrated charge-discharge machine to the discharge interface of the battery holder to draw power from the test battery box. Connect the discharge gun of the integrated charge-discharge machine to the test battery box and charge the test battery box with the electrical energy released from the test battery box to perform a discharge test on the test battery box; or,

[0092] Connect the power-taking gun of the integrated charge-discharge machine to the test battery box to draw power from the test battery box. Connect the discharge gun of the integrated charge-discharge machine to the discharge interface of the battery bracket to charge the test battery box with the power of the test battery box to perform a charging test on the test battery box.

[0093] Specifically, when the client receives a battery charging test command, it means that the test battery box needs to be charged, which means that the test battery box needs to be charged through the test battery box. In this case, the test battery box is equivalent to needing to be discharged. Therefore, the power gun of the charge-discharge machine can be connected to the test battery box to draw power from the test battery box. In addition, the discharge gun of the charge-discharge machine also needs to be connected to the discharge interface of the battery bracket to charge the test battery box with the power of the test battery box, so as to carry out the charging test of the test battery box.

[0094] Additionally, when the client receives a battery discharge test command, it indicates that the test battery box needs to be discharged. This means that the electrical energy released by the test battery box needs to be stored through the test battery box. In this case, the test battery box is equivalent to needing to be charged. Therefore, the power-taking gun of the charge-discharge machine can be connected to the discharge interface of the battery bracket to draw power from the test battery box. The discharge gun of the charge-discharge machine can be connected to the test battery box to charge the electrical energy released by the test battery box into the test battery box for discharge testing.

[0095] It should be noted that the charging and discharging machine has two types of charging guns: a power-on gun and a power-off gun. The charging and discharging machine can automatically switch between the types of charging guns, meaning that at least some of the charging guns can be used as both power-on and power-off guns, eliminating the need for frequent disassembly and reassembly of the charging guns.

[0096] In practical applications, when performing discharge tests on the test battery box, the test battery box is first hoisted onto the battery bracket. An external debugging harness and CAN module are used to establish a communication connection between the client and the test battery box for convenient control and data acquisition. The power-taking gun of the integrated charge-discharge unit is connected to the discharge interface on the battery bracket to draw power. The discharge gun of the integrated charge-discharge unit is then connected to the test battery box for energy recovery. The client can send a discharge command to activate the relay in the discharge circuit within the test battery box. The charging and discharging power and various protection parameters of the integrated charge-discharge unit can then be set, and the integrated charge-discharge unit can be started to verify the discharge function of the test battery box. The discharged energy is then transferred to the test battery box for recovery through the integrated charge-discharge unit. Similarly, when performing charging tests on the test battery box, power can be drawn from the test battery box. The charging gun of the integrated charge-discharge unit is connected to the charging interface on the battery bracket, and the energy in the test battery box is transferred to the test battery box to verify the charging function.

[0097] Step 106: Monitor the status information of the test battery box during the test process through the client.

[0098] Specifically, since the client communicates with the test battery box, the client can collect and display the status information of the test battery box during the test process through the battery management unit of the test battery box.

[0099] In addition, the charging and discharging unit can also collect the status information of the test battery box during the test process, and then perform fault detection on the test battery box based on this status information. For example, it can determine whether the collected data such as temperature, current or voltage of the test battery box exceeds the preset threshold. If so, it can be determined that the test battery box has a fault. In this case, the fault information can be displayed on its visual interface and the test process can be stopped.

[0100] This specification provides a battery testing method in one embodiment applied to a battery testing system. The battery testing system includes a charge / discharge integrated machine, a battery bracket, a test battery box, a test-compatible battery box, and a client. The battery bracket is equipped with a charge / discharge interface. The test battery box is mounted on the battery bracket and electrically connected to the charge / discharge interface. The test battery box is communicatively connected to the client. The method includes: upon receiving a battery testing command from the client, controlling the charge / discharge interface of the battery bracket to connect to the charge / discharge integrated machine, and controlling the charge / discharge integrated machine to connect to the test-compatible battery box; performing charge / discharge testing on the test battery box through the test-compatible battery box; and monitoring the status information of the test battery box during the testing process through the client. This embodiment uses a test-compatible battery box for charge / discharge testing, achieving energy recovery, thereby reducing energy waste, improving energy utilization efficiency, and possessing the advantages of being green, energy-saving, and economical. In addition, the embodiments in this specification use this battery testing system to perform charge and discharge tests on the test battery box, which can improve the portability and mobility of the battery testing system, solve the problem that the site power capacity is insufficient to meet the requirements of high-power testing technology, and also help to avoid the waste of discharge energy when each mass-produced product is tested after it leaves the production line. Furthermore, it helps to reduce the need to purchase high-power charge and discharge equipment, and also helps to save the equipment site area and the cost of laying the equipment's power cables.

[0101] Corresponding to the above method embodiments, this specification also provides battery box embodiments, such as... Figure 4 As shown, the battery box may include a bottom frame, a top frame, and a middle frame. The bottom frame and the top frame are spaced apart, the middle frame is located between the bottom frame and the top frame, and the middle frame is connected to both the top frame and the bottom frame. A battery mounting space is formed between the bottom frame and the top frame. The top frame is used to connect to the hoisting equipment. The battery pack is set in the battery mounting cavity and is connected to both the top frame and the bottom frame.

[0102] This manual also provides examples of battery testing systems, such as... Figures 2 to 5As shown in the illustration, this specification provides a battery testing system, including: a test battery box, a test-fit battery box, a battery bracket, a battery box bracket, a charge / discharge integrated machine, and a client. The battery bracket is equipped with a battery positioning seat, a charging interface, and a discharging interface. When the test battery box is seated on the battery bracket, the battery positioning seat and the test battery box are in a limiting engagement. The charging interface and discharging interface are electrically connected to the test battery box, respectively. The test-fit battery box is mounted on the battery box bracket. The charge / discharge integrated machine has several charging ports; some of these ports are detachably connected to the charging interface or the discharging interface, and some of these ports are electrically connected to the test-fit battery box to perform power transfer between the test-fit battery box and the test battery box.

[0103] The test battery box can be a large energy storage battery, for example, a specially manufactured large-size battery box, or a reused energy storage battery box used in heavy-duty trucks. The test battery box can include a frame and multiple battery packs housed within the frame. This test battery box can be a new battery box or an old one, as long as the stored energy meets the charge-discharge test requirements.

[0104] The integrated charge / discharge unit utilizes a bidirectional energy conversion system to transfer electrical energy between the test battery box and the test-compatible battery box, enabling charging and discharging of the test battery box. The unit includes a power-taking gun and a discharge gun. During discharge testing, the test battery box is first hoisted onto a battery bracket. An external debugging harness and CAN module are used to establish communication between the test computer (client) and the test battery box for convenient control and data acquisition. The power-taking gun of the integrated charge / discharge unit is connected to the discharge interface on the battery bracket to draw power, while the discharge gun is connected to the test-compatible battery box for energy recovery. The test computer sends discharge commands to control the relay closure in the discharge circuit within the test battery box. The charging / discharging power and various protection parameters of the integrated charge / discharge unit can then be set. Starting the integrated charge / discharge unit verifies the discharge function of the test battery box, and the discharged energy is transferred to the test-compatible battery box for recovery. During charging tests, power can be drawn from the test battery box and connected to the charging interface on the battery bracket via the integrated charging gun. The power in the test battery box is then transferred to the test battery box to verify the charging function.

[0105] It should be noted that the charging and discharging machine has two types of charging guns: a power-on gun and a power-off gun. The charging and discharging machine can automatically switch between the types of charging guns, meaning that at least some of the charging guns can be used as both power-on and power-off guns, eliminating the need for frequent disassembly and reassembly of the charging guns.

[0106] It should be noted that the structure and principle of the charging and discharging machine have long been publicly available technology. The embodiments in this specification do not improve the structure and principle of the charging and discharging machine; commercially available products can be used directly.

[0107] In some possible implementations, the battery holder has an electrical connector in the middle, which is electrically connected to the charging port and the discharging port respectively. When the test battery box is seated on the battery holder, the electrical connector is electrically connected to the test battery box. The electrical connector may include a charging connector and a discharging connector, with the charging connector connected to the charging port and the discharging connector connected to the discharging port.

[0108] In some possible implementations, the charging and discharging interfaces are located on opposite sides of the battery holder. This facilitates wiring between the interfaces and electrical connectors, does not interfere with the placement of the test battery box, and makes full use of space.

[0109] In some possible implementations, at least two charging ports are provided on one side of the battery holder, and at least two discharging ports are provided on the other side of the battery holder. By providing two charging ports and two discharging ports, the charging efficiency and discharging efficiency are improved.

[0110] In some possible implementations, the battery holder includes an upper frame, a lower frame, and multiple uprights. The upper and lower frames are spaced apart, and the uprights are located between the upper and lower frames, connecting the upper and lower frames respectively. The battery positioning seat, charging interface, and discharging interface are all located on the upper frame. The lower frame can be stably supported on the ground. The design of the uprights increases the height of the upper frame, facilitating the insertion and removal of the charging gun.

[0111] In some possible implementations, the battery holder is also provided with multiple battery guide seats, and the battery guide seats are provided with inclined guide surfaces. As the test battery box gradually approaches the battery holder from top to bottom, it can contact the inclined guide surfaces, which guide the test battery box to sit on the battery holder.

[0112] In some possible implementations, the battery box bracket includes at least two bracket bodies, which are spaced apart and arranged in parallel. Each bracket body is provided with an electrical connector, a battery positioning seat and a battery guide seat. Each bracket body can be used to install a test-fit battery box.

[0113] In this implementation scheme, the battery box bracket has two support bodies, which can simultaneously hold two test battery boxes, increasing the overall capacity. The two test battery boxes can be used in conjunction with one test battery box for charge-discharge testing. Alternatively, the two test battery boxes can be used separately with two other test battery boxes for testing, improving testing efficiency.

[0114] In some possible implementations, the battery box bracket includes multiple connecting beams, each of which is located between two adjacent bracket bodies and connected at both ends to the two adjacent bracket bodies respectively. The connecting beams connect the two bracket bodies to form a single unit.

[0115] In some possible implementations, the battery testing system includes a housing with multiple power connectors inside. Each power connector is electrically connected to a test battery box and is used to connect to the charging / discharging gun of a charging / discharging machine. The power connector includes a charging interface and a discharging interface. By configuring the housing, the charging and discharging interfaces of two test battery boxes are integrated in the same location, facilitating connection to the charging / discharging gun.

[0116] The battery testing system may also include a charger to recharge the test battery box when the total capacity decreases due to multiple power switching during multiple test cycles, so that the test battery box can continue to effectively cooperate with the test battery box for charge and discharge tests.
