[0017] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this document.

[0018] With the popularity of electric bicycles and electric tricycles, batteries, especially lithium batteries, are widely used, and the unsafe conditions caused by batteries have attracted great attention from users. Most of the accidents such as explosions and combustion during battery charging are caused by overcharging of the battery. Overcharging of the battery will increase the internal pressure of the battery, damage the structure, and generate a large amount of gas inside the battery, which will increase the internal pressure of the battery, causing the battery to deform, leak, and even explode; over-discharging of the battery will also cause the same harm to the battery. Whether the battery pack used in electric vehicles has overcharge and over-discharge protection functions, that is, whether the BMS (Battery Management System) of the battery pack has overcharge and over-discharge protection functions and the effectiveness of the protection functions are becoming increasingly important in battery use. Batteries without protection functions or with failed protection functions are extremely unsafe. Therefore, there is an urgent need for a charging system that can help users understand whether the battery they are using has a protection function to meet users' needs for battery safety.

[0019] In order to solve the above problems, the embodiment of the present disclosure provides a battery charging system with a safety detection function, which can realize a rapid safety detection after the battery is charged. Figure 1 As shown, it mainly includes a charging compartment 10, a charging system 20, a safety detection system 30 and a control system 40, and the control system 40 completes the coordinated control of the charging compartment 10, the charging system 20 and the safety detection system 30 to realize the charging operation and safety detection operation of the battery.

[0020] Specifically, the charging compartment 10 is mainly used to accommodate the battery 100 to be charged. Its shape and size can be set according to the commonly used battery size, or directly adopt a conventional charging compartment design. It should be noted that the charging compartment 10 should at least include electrodes corresponding to the positive and negative poles of the battery 100, and lead out positive and negative electrodes for charging or testing to serve as the positive and negative poles for connecting the battery 100 to the outside world. In addition, the charging compartment 10 should also have fire and explosion-proof functions, and temperature sensors and simple fire-fighting devices can be further installed inside it.

[0021] The charging system 20 mainly includes a sampling circuit 21 for real-time acquisition of battery power parameters, a DC charging power supply 22 for charging the battery 100 in the charging compartment 10, and a first switch group Q1 for switching the connection relationship between the charging compartment 10 and the DC charging power supply 22 and the safety detection system 30. Figure 1 As shown in the connection relationship, the sampling circuit 21 and the charging compartment 10 are always connected, which is equivalent to the sampling end of the sampling circuit 21 being continuously connected to the positive and negative poles of the charging compartment 10 (that is, the positive and negative poles presented to the outside by the battery 100) to ensure real-time power parameter collection; and the DC charging power supply 22 and the charging compartment 10 are controlled by the first switch group Q1 to determine whether they are connected.

[0022] In this embodiment, the power parameters collected by the sampling circuit 21 are primarily the battery's charging voltage and charging current. The specific circuit structure of the sampling circuit 21 can directly adopt a conventional sampling circuit design, and this embodiment does not limit its specific circuit structure implementation. The DC charging power supply 22 needs to meet the rated charging voltage of the battery 100. Its specific output voltage is typically 12V, or a DC charging power supply with adjustable output voltage can be selected based on actual needs, and the output voltage of the DC charging power supply can be adjusted in real time through the control system. The first switch group Q1 is primarily used to control the object actually connected to the charging compartment 10. If it is connected to a DC charging power supply, it indicates that it is currently in the charging process. If it is connected to the safety detection system 30, it indicates that it is currently in the safety detection process.

[0023] The safety detection system 30 in this embodiment primarily includes a high current generator 31 for detecting the battery's overcharge protection function, a variable load 32 for detecting the battery's over-discharge protection function, and a second switch group Q2 for switching the connection between the battery 100 and the high current generator 31 and the variable load 32, respectively. Whether the overcharge protection function test or the over-discharge protection function test is performed during the battery safety detection process depends on the specific connection object of the second switch group Q2. Finally, a control system 40 is used to control the switching of the first switch group Q1 and the second switch group Q2 to switch the connection between the battery and the charging system and the safety detection system, respectively. Simultaneously, the control system 40 uses the power parameters collected by the sampling circuit 21 as the basis for switching the switch groups, and determines the battery's charging results and safety detection results based on the power parameters under different battery operation conditions.

[0024] In some embodiments, the first switch group Q1 includes at least a first switch K1 and a second switch K2, and the second switch group Q2 includes at least a third switch K3 and a fourth switch K4. Each of the first to fourth switches K1, K4 is a single-pole double-throw (SPDT) switch. Specifically, the control system 40 adjusts the active terminals of the SPDT switches to connect the battery to different devices. In conjunction with the specific implementation functions of the switches, the fixed terminal of the first switch K1 is connected to the positive terminal of the battery 100, and the active terminal of the first switch K1 is connected to the first terminal of the DC charging power source 22 or the fixed terminal of the third switch K3. The fixed terminal of the second switch K2 is connected to the negative terminal of the battery 100, and the active terminal of the second switch K2 is connected to the second terminal of the DC charging power source 22 or the fixed terminal of the fourth switch K4. The active terminal of the third switch K3 is connected to the first terminal of the high-current generator 31 or the first terminal of the variable load 32. The active terminal of the fourth switch K4 is connected to the second terminal of the high-current generator 31 or the second terminal of the variable load 32. It should be noted that the single-pole double-throw switch used in the switch of this embodiment can be a mechanical switch, or can be implemented by an electromagnetic switch such as a solenoid valve or a relay, as long as the same function can be achieved. In addition, the two switches in the first switch group Q1 are synchronously controlled during actual regulation, that is, when the dynamic terminal of the first switch K1 is adjusted, the dynamic terminal of the second switch K2 is also adjusted synchronously. Similarly, when the dynamic terminal of the third switch K3 is adjusted, the dynamic terminal of the fourth switch K4 is also changed synchronously.

[0025] When the battery charging system of this embodiment is actually used, the battery should be charged first. After the charging operation is completed (i.e., the battery is fully charged), a safety check should be performed to ensure that the power parameter collection results during the safety check are accurate. Specifically, when the control system 40 determines that a new battery has been placed in the charging compartment 10, the control system 40 controls the active end of the first switch K1 to connect to the first end of the DC charging power supply 22, and controls the active end of the second switch K2 to connect to the second end of the DC charging power supply 22 to perform the charging operation on the battery 100. At the same time, during the charging process, the control system 40 continuously obtains the charging voltage and charging current of the battery 100 through the sampling circuit 21 to determine the current charging state of the battery. When the charging voltage reaches the rated voltage of the battery, it indicates that the battery is fully charged and the subsequent safety check steps can be performed.

[0026] In some embodiments, the battery charging system may have an operating interface. After the user places the battery into the charging compartment, the user can input the battery type, rated voltage, battery capacity and other parameters of the battery on the operating interface. The operating interface is communicated with the control system 40, and can be specifically presented through the display screen, and combined with input devices (such as a keyboard, mouse, or a touch panel on the display screen, etc.) to complete the input of the corresponding battery parameters. The control system 40 then obtains the above-mentioned battery parameters as the basis for regulating the various operating processes of the battery.

[0027] When the control system 40 determines that the charging voltage has reached the rated voltage of the battery, it controls the active terminal of the first switch K1 to connect to the fixed terminal of the third switch K3, and controls the active terminal of the second switch K2 to connect to the fixed terminal of the fourth switch K4, thereby performing a battery safety check. In practice, the battery safety function tested in this embodiment primarily refers to detecting whether the battery is equipped with a BMS board with overcharge and over-discharge protection functions and determining whether the BMS board is functioning properly. It does not test the overcharge or over-discharge protection of the battery itself.

[0028] The safety detection operation of this embodiment mainly includes the detection of the overcharge protection function and the over-discharge protection function, that is, respectively detecting the protection function of the BMS board for the battery under high current charging and high current discharging conditions. Specifically, when detecting the overcharge protection function, the control system 40 first controls the active end of the third switch K3 to be connected to the first end of the high current generator 31, and controls the active end of the fourth switch K4 to be connected to the second end of the high current generator 31, so that the positive and negative ends of the battery are connected to the two output ends of the high current generator 31; then, the control system 40 can adjust the output current of the high current generator 31 to perform an overcharge operation on the battery 100. The output current of the high current generator 31 can be set to a first preset multiple of the battery capacity C of the battery 100, for example, using a high current of 1C to 2C to charge the battery 100, and The charging voltage and charging current of the battery fed back by the sampling circuit 21 are detected in real time to determine the effectiveness of the battery overcharge protection function. Since the safety detection operation is performed after the charging operation is completed, the charging voltage collected by the sampling circuit during the overcharging process must be greater than or equal to the rated voltage of the battery. On this basis, if the charging current is detected to be 0 within the first preset time, it means that the battery has an overcharge protection function, that is, the battery has a BMS board and the BMS board functions normally. If the charging current is not detected to be 0 within the first preset time, it means that the battery does not have overcharge protection and there may be a safety hazard.

[0029] In some embodiments, the first preset time length can be set to any time length between 30 seconds and 150 seconds. If the first preset time length is too long, the excessive charging current may easily damage the battery, but too short a time length may cause inaccurate detection results. Therefore, this embodiment can adopt, for example, 120 seconds as the first preset time length to simultaneously meet the accuracy of the detection results and the safety of the battery detection process.

[0030] Specifically, when detecting the over-discharge protection function, the control system 40 controls the active end of the third switch K3 to connect to the first end of the variable load 32, and controls the active end of the fourth switch K4 to connect to the second end of the variable load 32. Simultaneously, the control system 40 adjusts the resistance of the variable load 32 to over-discharge the battery 100, causing the battery 100 to discharge at a current that is a second preset multiple of the battery capacity C, for example, 2C to 4C, which is 2 to 4 times the battery capacity. The control system 40 then detects changes in the charging voltage to determine the effectiveness of the battery over-discharge protection function. Within the second preset time period, if the control system 40 detects that the charging voltage becomes zero, the battery is determined to have the over-discharge protection function. Otherwise, the battery does not have the over-discharge protection function, which may pose a safety hazard. It should be noted that the variable load 32 is primarily a resistor with a variable resistance, and the control system controls the discharge current of the battery 100 by adjusting the resistance of the variable load 32.

[0031] In some embodiments, the second preset time duration is any duration between 1 and 5 seconds. For example, 5 seconds is used as an example. The control system begins timing when the second switch group Q2 is switched to connect to the variable load. If the charging voltage is detected to be 0 within 5 seconds, the battery is deemed to be in over-discharge protection mode. Otherwise, the battery is not protected. It should be noted that during the over-discharge protection detection process, if the charging voltage does not reach 0 within the second preset time duration, the control system 40 actively controls the active terminal of the third switch K3 and / or the fourth switch K4 to disconnect from the variable load 32, placing the battery in an open circuit state to prevent excessive discharge current from causing battery failure.

[0032] In fact, there is no specific execution order for the overcharge protection function test and the over-discharge protection function test performed on the battery. The control system can independently control whether to connect the variable load or the high current generator first. This embodiment does not limit the specific connection order.

[0033] In some embodiments, the control system 40 is further configured to, after the safety check operation on the battery 100 is completed, control the active terminal of the first switch K1 to connect to the first terminal of the DC charging power source 22, and control the active terminal of the second switch K2 to connect to the second terminal of the DC charging power source 22, so that the battery returns to a charging state. This is to replenish some power loss that may occur during the safety check, and to prevent the battery from being in a continuous overcharge or over-discharge state, which could affect battery safety. Furthermore, the control system 40 can also display the test results of the battery safety check on the user interface to intuitively inform the user of the current battery safety performance and charging results. In particular, if the battery has a safety hazard, the user can be promptly notified to prevent danger during subsequent use.

[0034] It should be understood that the specific form of the battery charging system disclosed in this embodiment can be a household battery charging device, which uses an independent charging compartment in conjunction with a control system (and display device) set in the compartment body to complete the charging operation and safety detection operation of the household electric vehicle battery. In fact, the battery charging system can also be a shared charging cabinet, which is formed by setting up an array of charging compartments to form the main body of the charging cabinet. Each charging compartment is configured with an independent charging system and safety detection system to meet the parallel implementation of processes in different charging compartments. The control system can control all charging compartments separately and record the safety detection results. When a user uses a shared charging cabinet to charge the battery, the control system can record its corresponding connection method and send a message to the user after the charging process and safety detection process are completed to prompt him to remove the battery. At the same time, the message can further carry the test results of the safety test to facilitate the user to understand the safety performance of its battery.

[0035] This embodiment uses a control system in conjunction with a switch group to switch between the battery charging process and the safety testing process. A high-current generator and a variable load are used during the safety testing process to detect whether the battery has overcharge and over-discharge protection. This allows for rapid safety testing during the charging process, helping users effectively troubleshoot battery safety and improving safety. Furthermore, using high current to detect overcharge and over-discharge directly and quickly changes the battery's state, effectively increasing the speed of battery testing and reducing adverse effects on the battery or circuit during testing.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
