[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Circuit breakers with built-in trip motors;

[0034] A first quick cable connector, one end of which is used to electrically connect to the battery pack, and the other end of which is electrically connected to the input end of the circuit breaker;

[0035] A second fast cable connector, one end of which is used to electrically connect to the discharge dummy load, and the other end of which is electrically connected to the output end of the circuit breaker; a battery parameter acquisition module, which is used to electrically connect to the battery pack;

[0036] A battery monitoring host, electrically connected to the battery parameter acquisition module;

[0038] The power module has an input end electrically connected to the other end of the first fast cable connector, and an output end electrically connected to the battery monitoring host, the serial port I / O control module and the trip motor in the circuit breaker.

[0039] The utility model can quickly connect the battery pack and the discharge dummy load by utilizing the first quick cable connector and the second quick cable connector, without removing the connecting cable between the battery pack and the charging rectifier device, thus avoiding the cumbersome cable connection and removal work in the prior art, and having high efficiency. In addition, the utility model effectively combines the circuit breaker, the battery parameter acquisition module, the battery monitoring host, the serial port I / O control module and the discharge dummy load, so that the battery pack capacity verification work is "simplified" and compatible with equipment from different manufacturers; at the same time, the battery pack capacity verification work is effectively managed by automatic control. During the battery capacity verification process, the power parameters of the battery pack are collected by the battery parameter acquisition module. The battery monitoring host stores the power parameters of the battery pack collected by the battery parameter acquisition module under the charge and discharge state, and outputs control instructions to the serial port I / O control module in combination with the threshold set internally. The serial port I / O control module forwards the instructions to the circuit breaker to control the action of the tripping motor in the circuit breaker, and finally the circuit breaker is automatically tripped (disconnected) to terminate the capacity verification work, making the battery pack capacity verification work more automated, greatly improving the automation level of the battery capacity verification work, improving work efficiency and equipment utilization, saving labor costs, reducing safety operation risks, and ensuring the safety of staff and equipment.

[0040] In some embodiments, the present invention further includes:

[0041] A power switch is electrically connected between the input end of the power module and the other end of the first fast cable connector. The first fast cable connector is specifically a current terminal block; the power switch is connected to the other end of the first fast cable connector through the input end of the circuit breaker.

[0042] Specifically, the positive and negative poles of the battery pack are connected to the power cable to the current terminal block, and the current terminal block is connected to the input end of the circuit breaker. After the power supply of the device is drawn from the input end of the circuit breaker, it passes through the power switch to the power module. The power module supplies power to the serial port I / O control module, the battery monitoring host, and the trip motor in the circuit breaker, so that the serial port I / O control module, the battery monitoring host, and the trip motor in the circuit breaker work normally, thereby ensuring that the battery pack capacity verification work is carried out normally. The setting of the power switch is convenient for controlling the state of the power supply of the power module to the outside, and thus convenient for controlling whether to carry out the battery pack capacity verification work at any time.

[0043] In some embodiments, the second quick cable connector includes a copper busbar electrically connected to the output end of the circuit breaker, and a quick connection button disposed on the copper busbar and used to electrically connect the discharge dummy load.

[0044] Specifically, the output end of the circuit breaker is connected to a copper bar, and the copper bar is equipped with a quick wiring button, through which the discharge dummy load can be quickly connected to the device of the utility model and removed from the device of the utility model.

[0045] In some embodiments, the utility model further comprises: a display, which is electrically connected to the battery monitoring host and the output end of the power module. Preferably, the display is a touch display; wherein the touch display and the battery monitoring host are connected by an RJ45 network cable.

[0046] Specifically, the touch display can set various parameters of the battery pack, including the number of single cells in the battery pack, the capacity of the battery pack, the charge and discharge voltage threshold alarm value, the internal resistance reference value, etc.; at the same time, the touch display can also display the various power parameters collected by the battery parameter acquisition module, for example, in the form of graphics and tables.

[0047] In some embodiments, the battery pack includes a plurality of single batteries connected in series; the battery parameter acquisition module includes:

[0051] A plurality of temperature collection units are electrically connected to the plurality of single storage batteries in a one-to-one correspondence;

[0052] Among them, one current acquisition unit, multiple voltage acquisition units, multiple internal resistance acquisition units and multiple temperature acquisition units are all electrically connected to the battery monitoring host.

[0053] Specifically, one current acquisition unit, multiple voltage acquisition units, multiple internal resistance acquisition units, and multiple temperature acquisition units are electrically connected to the battery monitoring host in a hand-in-hand manner via an RJ45 network cable, and the battery monitoring host automatically corresponds to the numbering of the single cells in the battery pack through Modbus protocol communication.

[0054] Specifically, the battery parameter acquisition module of the present invention can collect the voltage, internal resistance and temperature of the battery pack. Compared with the existing method of only collecting the voltage of the battery pack, the present invention manages the battery more timely and accurately. During the battery pack capacity verification process, the capacity verification work is automatically terminated according to the battery cut-off voltage, capacity, time and other thresholds, making the battery pack capacity verification work more automated.

[0055] In some embodiments, the battery monitoring host and the serial port I / O control module are electrically connected via an RS485 cable.

[0056] In some embodiments, the rated voltage of the battery pack is DC24V or DC220V; correspondingly, the power module is specifically a DC24V to DC12V power module or a DC220V to DC12V power module.

[0057] The overall working process of the utility model is as follows:

[0058] 1. When checking the capacity of the battery pack, first connect the positive and negative cables of the discharge dummy load directly to the quick connection button and close the circuit breaker.

[0059] 2. Set various threshold parameters such as battery cut-off voltage, discharge capacity, discharge time, etc. on the touch display according to the specifications of the battery pack, and send them to the battery monitoring host.

[0060] 3. Start the discharge dummy load, and the battery monitoring host will automatically store the discharge data.

[0061] 4. During the capacity verification of the battery pack, if any of the conditions such as the battery cut-off voltage, discharge capacity, and discharge time are met, the battery monitoring host immediately outputs a control instruction to the serial port I / O control module, the normally open contact of the serial port I / O control module closes, the circuit breaker trip motor is powered on, the circuit breaker is automatically disconnected, and the discharge dummy load stops working.

[0062] 5. Use the touch display USB interface to automatically read the battery pack capacity verification data.
