DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all the embodiments.

[0032] Please refer to Figures 1 to 6 An embodiment provided by the application is a kind of integrated UPS power module system of data center IDC machine room, including input and output power distribution module 2, battery pack module 1, battery power control module 3, battery intelligent monitoring and management module 4, built-in temperature control module 5, automatic fault detection alarm module 6.

[0033] ​Input / output power distribution module 2 is used to complete the input and output distribution of system power. It is the main circuit in the system and its function is to protect the electrical components connected to it. Battery pack module 1 is the main energy storage unit of the system and provides power to the entire system. Battery power control module 3 is connected to battery pack module 1 and is used to monitor the charging and discharging current and voltage of the battery in real time, and to control the charging power and discharging power of battery pack module 1. Battery intelligent monitoring and management module 4 is connected to battery pack module 1 and is used to collect data on battery voltage, current, internal resistance and health status, so as to realize the monitoring of various states of battery pack module 1.

[0034] The built-in temperature control module 5 is installed in the cabinet of the battery pack module 1 and is used to monitor the ambient temperature and the battery temperature itself, and to adjust the ambient temperature and the battery temperature. The automatic fault detection and alarm module 6 is connected to the battery intelligent monitoring and management module 4 and the built-in temperature control module 5 and is used to diagnose various battery faults and generate alarm information.

[0035] The input / output power distribution module 2 includes an input / output circuit breaker 201, an output / output circuit breaker 202, a surge protector 203, and a multi-function energy meter 204. The input / output circuit breaker 201 and the output / output circuit breaker 202 provide overload protection, short-circuit protection, and undervoltage protection for the electrical components at each stage of the circuit. The surge protector 203 is used to protect the electrical components at each stage of the circuit from lightning overvoltage, operational overvoltage, and power frequency transient overvoltage. The multi-function energy meter 204 is used to measure the input and output power in the circuit.

[0036] Battery module 1 includes multiple battery compartments 101 and lithium battery packs 102. The lithium battery packs 102 are installed in the battery compartments 101, and the lithium battery packs 102 in the multiple battery compartments are connected in series by wires.

[0037] The battery power control module 3 includes a pulse width modulation unit 301, a charging voltage detection unit 302, a discharging voltage detection unit 303, and a discharging control switch 304. The pulse width modulation unit 301 and the charging voltage detection unit 302 are connected in parallel in the charging circuit of the battery pack module 1, the discharging voltage detection unit 303 is connected in parallel in the discharging circuit of the battery pack module 1, and the control switch is connected in series in the discharging circuit of the battery pack module 1.

[0038] The pulse width modulation circuit and voltage detection circuit are connected in parallel in the charging circuit of the battery pack module 1. The charging voltage detection unit 302 can detect the charging voltage of the lithium battery pack 102 during charging and feed back the detected voltage data to the pulse width modulation unit 301. The pulse width modulation unit 301 maintains the charging voltage of a single lithium battery pack 102 at 380V. The discharge voltage detection unit 303 detects the discharge voltage of the lithium battery pack 102 during charging and controls the on / off state of the entire battery pack module 1 in the discharge circuit through the discharge control switch 304.

[0039] The battery intelligent monitoring and management module includes: a data acquisition unit, used to collect the voltage and temperature of each battery cell, as well as the total current and internal resistance of the battery pack; a status evaluation unit, used to calculate the battery's state of charge, health status, and remaining life based on the collected data; and a data storage unit, used to store the battery's historical operating data and fault records.

[0040] The built-in temperature control module 5 includes: a temperature sensor array attached to the surface of the lithium battery pack 102 of the battery pack module 1, used to detect the ambient temperature and the internal temperature of the lithium battery pack 102; a semiconductor cooling chip and a heating chip, both installed on the front and rear sides of the battery compartment 101, used to actively heat or cool the battery compartment 101 and the lithium battery pack 102; a speed-regulating fan installed on one side of the battery compartment 101, used to circulate air inside the battery compartment 101; and a temperature control unit used to start or stop the semiconductor cooling chip, the heating chip, and the speed-regulating fan.

[0041] The built-in temperature control module 5 activates cooling, heating, or ventilation modes based on the ambient temperature and the operating temperature of the lithium battery pack 102, thereby regulating the ambient temperature and the operating temperature of the lithium battery pack 102. The built-in temperature control module 5 also includes an internal temperature detection unit, which is connected to the lithium battery cells and can directly detect the cell temperature. When the temperature of any lithium battery cell exceeds 30 degrees Celsius, the temperature control unit controls the semiconductor cooling chip and speed-regulating fan to start, thereby cooling the lithium battery cell.

[0042] When all internal temperature detection units detect that the temperature of the lithium battery cell is less than 30 degrees Celsius, the temperature control unit controls the semiconductor cooling chip and speed-regulating fan to stop operating, thereby avoiding excessive power waste.

[0043] When the temperature sensor detects that the ambient temperature is less than 10 degrees Celsius, the heating element is activated to heat the ambient temperature and maintain it at 20℃-25℃.

[0044] Based on the above embodiments, when the temperature sensor in the external environment detects that the ambient temperature is greater than 30 degrees Celsius, the temperature control unit first controls the thermoelectric cooler to run for 60 minutes. Under this operating state, the cold air generated by the thermoelectric cooler will gradually sink to the bottom of the battery compartment. After 60 minutes, the temperature control unit then controls the thermoelectric cooler to stop running and then turns on the variable speed fan to run for 60 minutes. The blowing action of the variable speed fan will rapidly circulate the cold air in the battery compartment. In this setting, the thermoelectric cooler and the variable speed fan run alternately. Compared with the thermoelectric cooler and the variable speed fan running simultaneously, the thermoelectric cooler in this setting will not experience the phenomenon of the newly generated cold air being blown away. The operation of the thermoelectric cooler alone allows the cooled air to settle, resulting in a better cooling effect. Moreover, at the same time, the thermoelectric cooler and the variable speed fan run independently rather than synchronously, which also reduces the overall energy consumption of the thermoelectric cooler and the variable speed fan.

[0045] The battery intelligent monitoring and management module 4 and the automatic fault detection and alarm module 6 upload the processed data and alarm information to the remote network terminal through the communication interface; the fault diagnosis logic of the automatic fault detection and alarm module 6 includes:

[0046] Voltage fault diagnosis: Determine whether the voltage of a single lithium battery pack 102 exceeds the preset overvoltage or undervoltage threshold;

[0047] Temperature fault diagnosis: Determine whether the temperature of a single lithium battery pack 102 exceeds the preset high or low temperature threshold;

[0048] Internal resistance fault diagnosis: By comparing the current internal resistance value of the lithium battery pack 102 with the initial internal resistance value of the lithium battery pack 102, it is determined whether the rate of change of the internal resistance of the lithium battery pack 102 exceeds the reasonable range.

[0049] Consistency fault diagnosis: By analyzing the voltage differences of each lithium battery pack 102, it is determined whether the voltage of each lithium battery pack 102 is the same.

[0050] The automatic fault detection and alarm module 6 features multi-level alarms, including early warning, general alarm, and emergency alarm. It performs different fault handling actions based on the fault level, including logging, audible and visual alarms, limiting charging power, or actively disconnecting the faulty battery circuit.

[0051] If the discharge voltage detection unit 303 detects that the voltage of a single lithium battery pack 102 is greater than 360V, it is considered overvoltage; if the voltage of a single lithium battery pack 102 is less than 280V, it is considered undervoltage. Overvoltage and undervoltage faults trigger an emergency alarm. In the emergency alarm, the automatic detection alarm module will issue an audible and visual alarm and actively cut off the discharge circuit of the faulty battery through the control switch in the battery power control module 3.

[0052] When the internal temperature detection unit detects that the cell temperature of a single lithium battery pack 102 is greater than 45°C, the entire lithium battery pack 102 is in a high temperature fault. The high temperature fault triggers the automatic fault detection alarm module 6 to generate a general alarm, activate the audible and visual alarm, and limit the charging current.

[0053] The automatic fault detection and alarm module 6 can detect the internal resistance of a single lithium battery pack 102. If the internal resistance of a single lithium battery pack 102 increases by more than 25% of the initial value, it is considered an internal resistance fault. At the same time, it can also detect the voltage of each lithium battery pack 102 and record and count the voltage of each lithium battery pack 102 to determine the consistency of all lithium batteries. If the voltage difference between the largest and smallest lithium battery pack 102 is >150mV, it is considered a consistency fault. In summary, the internal resistance fault and the consistency fault trigger an early warning. The storage unit in the automatic fault detection and alarm module 6 stores the warning, records it, and displays it on the network terminal.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
