Detailed Implementation

[0013] The following descriptions of the embodiments are made with reference to the accompanying drawings, illustrating specific embodiments in which the present invention can be implemented. Directional terms used in this invention, such as up, down, front, back, left, right, inside, outside, side, etc., are merely for the purpose of referring to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding the present invention, and not for limiting the present invention. In the drawings, structurally similar units are denoted by the same reference numerals.

[0014] The following description, in conjunction with the accompanying drawings, further clarifies the specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit.

[0015] See appendix Figures 1 to 2The present invention includes an energy storage battery 1 and a controller 2. The energy storage battery 1 is provided with a first control circuit 101, a second control circuit 102, a charging and discharging circuit 103, a first display circuit 104 and a plurality of battery packs 105. The second control circuit 102 is connected to the first control circuit 101, the charging and discharging circuit 103 and the first display circuit 104 respectively. The battery packs 105 are connected to the first control circuit 101 and the second control circuit 102 respectively. The charging and discharging circuit 103 is provided with a plurality of relays 106 controlled by the second control circuit 102.

[0016] The controller 2 is equipped with a third control circuit 201 and a second display circuit 202 and a rotary switch 203 connected to the third control circuit 201. A connecting wire group 3 is provided between the controller 2 and the energy storage battery 1. The third control circuit 201 sends instructions to the second control circuit 102 for controlling the relay 106 through the connecting wire group 3.

[0017] Furthermore, the rotary switch 203 is used to select and confirm the function of the third control circuit 201.

[0018] Furthermore, the first control circuit 101 collects the SOC, SOE, and SOH data of the battery pack 105 and sends them to the second control circuit 102. The second control circuit 102 sets a set of independent address codes for each battery pack 105 for factory identification, so that the controller 2 can retrieve the SOC, SOE, and SOH data of the battery pack 105 and display the data on the second display circuit 202.

[0019] When the energy storage battery 1 and controller 2 are not connected, the tabs on the energy storage battery 1 are not powered. In this case, even short-circuiting the two positive and negative tabs on the energy storage battery 1 will not cause a short circuit. At the same time, it also avoids the risk of the circuit board inside the energy storage battery 1 malfunctioning due to prolonged power supply, making the circuit board and battery pack 105 inside the energy storage battery 1 safer. If the energy storage battery 1 is stolen alone, it cannot be used without a suitable controller 2 connected to it.

[0020] When the energy storage battery 1 is needed, it is simply connected to the controller 2. The third control circuit 201 energizes the first control circuit 101 and the second control circuit 102, activating them. At this time, the first control circuit 101 detects the temperature and voltage of each battery pack 105 and sends this data to the third control circuit 201 via the second control circuit 102. The third control circuit 201 displays this data on the second display circuit 202. By selecting the function to start the battery pack 105 via the rotary switch 203, the third control circuit 201 sends a command to the second control circuit 102 to start the battery pack 105. The second control circuit 102 controls the relay 106 to connect the complete charging and discharging circuit, allowing the battery pack 105 to discharge or be charged. Through the above design, the safety of the energy storage device 1 is greatly guaranteed, and the controller 2 acts as the key to unlock the energy storage device 1.

[0021] This newly developed product disclosed in this utility model is an EMS integrated module specifically designed to implement control functions for energy storage batteries. The first control circuit 101 has an AFE analog front-end chip for acquiring SOC, SOE, and SOH data of the battery pack 105, and the second control circuit 201 has an MCU chip for circuit control.

[0022] Function 1: The EMS integrated module collects data based on charging / discharging current, temperature, and the ratio of stored capacity to total capacity in the battery pack. It then calculates the SOC, SOE, and SOH values, saves the data, and transmits it to the charge / discharge controller via protocol communication. The current battery status is displayed.

[0023] Function 2: High-level equilibrium:

[0024] The battery pack 105 exhibits inconsistencies due to internal differences or varying external usage conditions. Furthermore, variations in electrolytic density, temperature, and self-discharge rates among individual battery packs during use can lead to inconsistencies that accumulate over time. These inconsistencies primarily affect the following aspects:

[0025] 1. Reduce overall capacity

[0026] 2. Shortens battery life

[0027] 3. Limit overall charging and discharging power

[0028] 4. Impact on battery safety performance

[0029] When the EMS is connected to the charge / discharge controller 2 in the system, the second display circuit 202 will display the health status of the battery pack 105, display the voltage of each battery pack 105, and also display the voltage difference between each battery pack 105.

[0030] When maintenance is required, press the maintenance entry button, and the system will automatically repair the battery. The repair process is as follows: the charger voltage is stopped by relay 106, and the battery voltage is stopped before the SOC value is calculated to obtain accurate data. Then, another 5V power supply is used to quickly replenish the battery pack 105 with the highest voltage in the 16-cell battery pack 150 as a reference value, so that the voltage of each group is consistent and the battery pack 105 returns to the optimal state.

[0031] Function 3 Battery Address Code ID:

[0032] Each battery pack 105 has its own address code ID card at the factory, which allows the status and information of the battery pack 105 to be viewed during remote operation and maintenance or system operation and maintenance. This makes it more convenient for energy storage use. In the energy storage cabinet, hundreds of battery packs 105 are used in series and parallel. Because they have electronic ID cards with address codes, the system can easily check the health status of each battery, which facilitates operation and maintenance and brings the batteries back to their optimal state.
