Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to an integrated energy storage and charging device and equipment. Background Technology

[0002] An integrated energy storage and charging device is a system that organically combines photovoltaic energy storage and charging devices. It can both store electrical energy and provide charging services for various electrical devices when needed. With the vigorous development of the new energy industry and the ever-increasing demand for efficient energy utilization, integrated energy storage and charging devices will play a key role in building smart grids, promoting green travel, and achieving sustainable energy development, becoming an important development direction in the future energy field.

[0003] Currently, existing integrated energy storage and charging devices have significant shortcomings in battery safety monitoring and protection, resulting in poor overall safety. For battery safety monitoring, most devices rely solely on simple temperature sensors for anomaly detection; however, this single monitoring method is insufficient to accurately capture early signs of battery thermal runaway. When a battery in an integrated energy storage and charging device catches fire, the fire spreads rapidly within a short time, releasing large amounts of toxic and harmful gases. This not only causes severe damage to surrounding equipment and the environment but also endangers human lives. Due to the lack of effective firefighting measures, personnel are often helpless when faced with battery fires and can only wait for firefighters to arrive, which significantly delays firefighting efforts and increases the losses caused by the fire.

If pressed, it generates emergency stop status information. The overpressure sensor is installed at each output terminal of the charging module and monitors the output voltage of the energy storage and charging body. When the output voltage exceeds a set threshold, it generates overpressure status information. The water level sensor is installed in areas of the integrated energy storage and charging device 100 where water may accumulate. The water level sensor detects the water level inside the device and generates water level status information when the water level exceeds a safe height. The access control switch can be a mechanical switch installed on the edge of the door or the door frame of the integrated energy storage and charging device 100. When the door is opened, the switch pops up and generates access control status information. After receiving the safety status information, the first control module 114 and the second control module 119 can perform corresponding operations according to the preset processing strategy. Upon receiving an emergency stop status message, the first control module 114 stops the energy storage operation, and the second control module 119 stops the charging operation to ensure the safety of personnel and equipment. Upon receiving an overvoltage status message, the second control module 119 controls the charging module to reduce the voltage. Upon receiving water level status information and access control status information, the first control module 114 issues an alarm.

[0083] In one possible implementation, see [reference] Figure 4 As shown, the charging compartment 110 of the integrated energy storage and charging device 100 is also equipped with a fault warning module 125;

[0084] The input terminal of the fault warning module 125 is connected to the first control module 114 and the second control module 119;

[0085] The fault warning module 125 is used to provide audible and visual alarms under the control of the first control module 114 and the second control module 119.

[0086] exist Figure 4In the integrated energy storage and charging device 100 shown, a fault warning module 125 is disposed on the side of the integrated energy storage and charging device 100. The input terminal of the fault warning module 125 is connected to the output terminals of the first control module 114 and the second control module 119 via wires. The first control module 114 monitors the operating status of the energy storage device, and the second control module 119 monitors the operating status of the charging device 117 in real time. When a fault is detected in either the energy storage device or the charging device 117, the first control module 114 and the second control module 119 control the fault warning module 125 to activate an audible and visual alarm. The audible alarm can use a buzzer to emit alarm sounds of different frequencies and rhythms, and the visual alarm can use flashing lights of different colors to distinguish different fault types. The fault warning module 125 can use a high-brightness LED flashing light as a visual alarm, with different colors corresponding to different faults. A high-decibel buzzer is used as the audible alarm device, with different alarm sound modes set to correspond to different faults.
