Description

Technical Field

[0001] The utility model relates to the field of electronic technology, in particular to a detection device for a 1P16S battery module. Background Art

[0002] The 1P16S battery module is a common lithium-ion battery pack configuration, widely used in electric vehicles, energy storage systems and other equipment with high energy efficiency requirements. The "1P16S" here represents the series-parallel connection of battery modules, where "1P" means that all battery cells are connected in parallel in only one group, that is, all battery cells operate at the same voltage, and the current can be increased by connecting all battery cells in parallel; "16S" means that there are 16 battery cells connected in series, and the voltage of each battery cell will be accumulated to form a higher total voltage output. For example, if the nominal voltage of each battery cell is 3.2V, then the total voltage of 16 battery cells after series connection is 52V.

[0003] With the development of new energy storage systems, battery modules have been widely used as core components. The detection and management of battery modules are the key to ensuring their normal operation.

[0004] Traditionally, battery module testing often involves using multiple testing devices to test various data points of the battery module separately. Computer equipment then integrates and processes the measured data to determine whether the battery module is operating normally. However, since this method involves using a large number of devices, workers need to frequently change testing equipment, which increases the workload and affects testing efficiency.

[0005] In addition, when testing battery modules at different locations, workers are required to carry a lot of testing equipment, which increases the workload of the workers.

[0006] Therefore, we propose a device that can reduce the workload of workers and improve the efficiency of battery module inspection. Utility Model Content

[0026] The technical solution of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, these are merely corresponding to the drawings of the present invention and are for the convenience of describing the present invention. They do not indicate or imply that the devices or components referred to must have a specific direction.

[0027] Example 1 is:

[0028] Combined with attachment Figure 1-2 The 1P16S battery module detection device includes a box 1, the box 1 is provided with a socket for connecting the battery module 7, and a screen 2;

[0029] The box body 1 is provided with a BMS module 3 electrically connected to the socket, and a power supply module 4 for supplying power to the screen 2 and the BMS module 3, and the BMS module 3 is electrically connected to the screen 2;

[0030] In addition, the box body 1 can also be provided with a button for controlling the start and stop of the power module 4, and a plurality of indicator lights, wherein the BMS module 3 controls the corresponding indicator lights to light up according to the status of the battery module 7 detected and judged, thereby reminding the staff of the status of the battery module 7 currently being detected;

[0031] It should be noted that the indicator light is also powered by the power module 4;

[0032] The screen 2 can receive the working status data of the battery module 7 collected and judged by the BMS unit, so that the staff can intuitively see the working status information of the battery module 7 during the inspection, so that the staff can quickly judge the operating status of the battery module 7;

[0033] In particular, the screen 2 adopts a display of model NL6448BC33-70K;

[0034] When the output wire of the battery module 7 is plugged into the socket, the BMS module 3 is connected to the battery module 7, and the detection process of the BMS module 3 is as follows:

[0035] 1) Data collection:

[0036] The BMS will periodically or continuously collect multiple key parameters of the battery module 7, including but not limited to:

[0037] Cell voltage: monitors the voltage of each battery module to detect any imbalance or fault;

[0038] Total Voltage: Measures the voltage of the entire battery pack.

[0039] Temperature: The built-in temperature sensor monitors the temperature of the battery module to prevent overheating or overcooling.

[0040] Current: Measures the current during charging and discharging for energy management and predicting remaining battery capacity.

[0041] Battery Pack SOCState of Charge: Estimates the remaining battery power.

[0042] SOHState of Health: Assess the health of the battery, usually by measuring internal resistance and comparing it with historical data.

[0043] 2) Data Analysis

[0044] The BMS analyzes the collected data and identifies any abnormal conditions such as voltage imbalance, excessively high or low temperatures, and excessive current.

[0045] 3) Communication and reporting:

[0046] The BMS communicates with screen 2 to display battery status information.

[0047] In addition, the power module 4 includes a battery 41 and an AC / DC step-down unit 42, and the box body 1 is provided with a charging socket, which is electrically connected to the battery 41 through the AC / DC step-down unit 42;

[0048] Since the battery 41 has an energy storage function, the power supply does not need to be replaced during the operation of the device, which means that long-term operation can be achieved, thereby improving the integration level of the device.

[0049] By connecting the charging socket to 220V AC power, the AC power can be rectified and stepped down by the AC / DC step-down unit 42 to charge the battery 41, thereby enabling the device to detect the battery module 7 for a long time, reducing the time required to replace the battery of the device, and thus improving the detection efficiency of the device.

[0050] In addition, it should be noted that when the battery 41 supplies power to the screen 2 and the BMS module 3, it will first step down the voltage to the voltage required by the corresponding module before supplying power to it.

[0051] Example 2 is:

[0052] On the basis of Example 1, the sockets are further limited, that is, the number of the sockets is set to multiple, and the multiple sockets are electrically connected to the BMS module 3; the increase in the number of sockets means that the device can simultaneously connect to multiple groups of battery modules 7, and simultaneously perform status detection on multiple battery modules 7 through the BMS module 3, that is, the staff can complete the status detection of multiple groups of battery modules 7 in one place, effectively reducing the workload of the staff and alleviating their work intensity.

[0053] In addition, a sorting module 5 and a control module 6 are provided in the box 1. The signal input end of the sorting module 5 is electrically connected to a plurality of sockets, and the selection control end of the sorting module 5 is electrically connected to the control module 6. Since the status of multiple groups of battery modules 7 need to be detected at the same time, the basic BMS module 3 needs to be improved, thereby making the structure of the BMS module 3 more complicated so that the detection of multiple groups of battery modules 7 can be completed at the same time.

[0054] Improvements to the basic BMS module 3 often involve:

[0055] 1) Hardware Architecture:

[0056] The BMS hardware design must be able to support the input of voltage, current, and temperature sensors of multiple battery packs, which means that the BMS motherboard needs to have sufficient input channels and sufficient processing power;

[0057] 2) Software algorithm:

[0058] The BMS software needs to be able to process and analyze data from multiple battery packs, perform independent SOCState of Charge and SOHState of Health calculations, and implement corresponding battery management strategies;

[0059] 3) Communication capabilities:

[0060] The BMS for multiple battery packs needs to have strong communication capabilities and be able to communicate with all battery packs at the same time; etc.

[0061] Therefore, through the sorting module 5, when multiple groups of battery modules are connected, different battery modules 7 can be controlled to connect with the BMS module 3. The basic BMS module 3 can be used to perform status detection on multiple groups of battery modules 7 respectively. Although the detection time is longer, it effectively simplifies the overall structure of the device.

[0062] It should be noted that the sorting module 5 specifically controls the operation of different battery modules 7 according to the control instructions issued by the control module 6;

[0063] The control module 6 is electrically connected to the BMS module 3 and the power module 4 respectively; the control module 6 can receive the detection progress of the battery module 7 in the BMS module 3. When the BMS module 3 completes the detection of a group of battery modules 7, it sends a control instruction to the sorting module 5, allowing the sorting module 5 to switch to another battery module 7, and allowing the BMS module 3 to detect the next group of battery modules 7.

[0064] In particular, the sorting module 5 adopts a CD4051BE model multiplexer.

[0065] In particular, the control module 6 uses an XC7A50T FPGA chip, which has:

[0066] ①High performance and low power consumption:

[0067] The chip uses an advanced 7nm process, which can provide high performance while maintaining low power consumption, and is suitable for application scenarios that require high performance and low energy consumption;

[0070] ③ Rich I / O resources:

[0071] Supports multiple high-speed I / O standards, such as PCIe, USB, HDMI, etc., to meet the interface requirements of different application fields;

[0072] ④Integrated storage resources:

[0073] With 50K logic cells and 1.2K RAM blocks, it can realize complex logic design and storage requirements, supports distributed storage and block RAM, and is suitable for high-speed data processing and storage;

[0074] ⑤Multifunctional application:

[0075] Applicable to multiple fields such as communications, medical treatment, industrial control, automotive electronics, etc., it can realize high-speed data transmission and processing, image processing, automatic control, intelligent driving and other functions;

[0076] ⑥High clock frequency:

[0077] Supporting clock frequencies up to 3.3GHz, it can handle large amounts of data and high-intensity computing tasks, providing fast processing speeds;

[0078] ⑦Low core voltage:

[0080] ⑧Support multiple configuration methods:

[0081] Including JTAG and SPI configuration methods to facilitate user programming and debugging;
