Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a wireless control circuit, a wireless control module and an energy storage device. Background Technology

[0002] Currently, technologies for storing electrical energy are widely used. For example, in a residential energy storage device, electrical energy can be stored using multiple independently configured energy storage batteries. These individual batteries can be extracted from the device for individual use, and locking and unlocking operations are performed via corresponding locking modules during battery insertion and removal. Referring to the published patent CN223269773U, it primarily uses Bluetooth for remote door opening, only achieving the remote door opening function. It cannot obtain the status information of the energy storage batteries, making it impossible to promptly detect faulty batteries.

[0003] Therefore, there is a need for a lock control technology solution for residential energy storage devices that can not only enable remote door opening but also obtain real-time status information of the energy storage battery. Utility Model Content

[0074] The first BMS interface P2 is used to connect to the BMS terminal of the first expanded capacity battery module, and its charge and discharge control terminal is electrically connected to the AC input terminal of the first rectifier module.

[0075] The positive DC output of the first rectifier module is electrically connected to the control input pin L1+ of the first lock socket P3, and its negative DC output is electrically connected to the output terminal of the output control switch and connected to the zero level GND_0.

[0076] The input terminal of the output control switch is electrically connected to the control output pin L1 of the first lock socket P3;

[0077] The power supply pin of the first lock socket P3 is used to connect to the first operating voltage VCC1, and its grounding pin GND1 is used to achieve grounding.

[0078] In this embodiment, the wireless module can be a conventional setup, such as an ESP32 module that includes both Bluetooth and Wi-Fi functionality. The main control module can be implemented based on a conventional microcontroller. It can interact with the outside world via the wireless module and with the main battery module via the communication module. It can remotely unlock the battery based on the BMS (Battery Management System) and obtain the status information of the energy storage batteries in the main battery module and the first expansion battery module in a timely manner, allowing for the timely detection of problematic energy storage batteries and facilitating timely maintenance. The communication module can be implemented based on a conventional CAN transceiver to convert the logic level signals of the MCU (main control module) into the differential level signals required by the CAN bus, and simultaneously convert the differential level signals received on the CAN bus back to logic level signals. The main BMS interface P1 is a conventional BMS interface used to connect to the BMS of the main battery module. The first BMS interface P2 is a conventional BMS interface used to connect to the BMS of the first expansion battery module. The first rectifier module can be implemented based on a conventional rectifier. The output control switch can be a conventional switch, including both on and off states. The first lock socket P3 can use a conventional electromagnetic lock interface. The charge / discharge control terminal of the first BMS interface P2 consists of CTL1 and CTL2 pins, used to implement the charge / discharge control of the first expanded capacity battery module. The first operating voltage VCC1 can be 12V. Zero level GND_0 can be understood as a voltage level of 0V.

[0079] In one specific implementation, the main battery module is defaulted to the main BMS interface P1. A first electromagnetic lock is connected to the first lock socket P3. The first electromagnetic lock is used to lock the door of the first battery compartment, which is used to accommodate the first expansion battery module. The output control switch is turned on. The power supply pin of the first lock socket P3 is connected to 12V, its ground pin GND1 is grounded, and its control output pin L1- is connected to zero level GND_0 through the output control switch. When the first battery compartment is empty, the first BMS interface P2 is idle, its CTL1 and CTL2 pins have no signal, the first rectifier module has no DC output, the control input pin L1+ of the first lock socket P3 is low, and the first electromagnetic lock is in the unlocked state. At this time, the first expanded battery module is placed into the first battery compartment. The first expanded battery module is electrically connected to the first BMS interface P2. The BMS in the main battery module controls the BMS in the first expanded battery module to enter charging mode. Charging control signals (which can be considered as AC power) are present on the CTL1 and CTL2 pins of the first BMS interface. The first rectifier module has DC power output. The control input pin L1+ of the first lock socket P3 is at a high level, and the first electromagnetic lock is in the locked state. When the first expanded battery module is in the first battery compartment, the BMS of the main battery module controls the BMS in the first expanded battery module to enter charging or discharging mode by default, or alternate between charging and discharging modes. That is, charging or discharging control signals (AC power) are always present on the CTL1 and CTL2 pins of the first BMS interface, and the first electromagnetic lock is always in the locked state. After a period of time, assuming the first expanded battery module needs to be removed, the external terminal can wirelessly send an unlock signal for the first battery compartment to the wireless module. The unlock signal is parsed by the main control module and sent to the BMS of the main battery module through the communication module. After receiving the unlock control signal, the BMS of the main battery module controls the BMS in the first expanded battery module to exit the current charging or discharging mode. The CTL1 and CTL2 pins of the first BMS interface have no charging or discharging control signal (no AC power), the first rectifier module has no DC power output, the control input pin L1+ of the first lock socket P3 becomes low, and the first electromagnetic lock enters the unlock state.

Its DC output positive pin is electrically connected to the negative terminal of the second diode D2 as the DC output positive terminal of the second rectifier module, and its DC output negative pin is electrically connected to the positive terminal of the second diode D2 as the DC output negative terminal of the second rectifier module.

[0089] In this embodiment, the first rectifier D10 and the second rectifier D20 can be conventional rectifiers, such as the DB107S rectifier. The first diode D1 and the second diode D2 can be conventional diodes, such as TVS diodes. In specific implementation, the output control switch can be connected to the circuit through a switch interface P0. The input terminal of the output control switch is connected to pin 1 of the switch interface P0, and its output terminal is connected to pin 2 of the switch interface P0. A conventional anti-reverse current D11 diode can be placed between the switch interface P0 and the control output pin L1- of the first latch socket P3. A conventional anti-reverse current D21 diode can be placed between the switch interface P0 and the control output pin L2- of the second latch socket P5. Figure 3 The CAN terminals of the first BMS interface P2 and the second BMS interface P4 can be represented by the CH and CL pins. The first BMS interface P2 and the second BMS interface P4 also include digital input (DI) and digital output (DO) pins in the BMS, which are the interfaces for status monitoring and control between the BMS and external devices. The digital output (DO) pin of the main BMS interface is connected to the digital input (DI) pin of the second BMS interface P4, the digital output (DO) pin of the second BMS interface P4 is connected to the digital input (DI) pin of the first BMS interface P2, and the digital output (DO) pin of the first BMS interface P2 is connected to the digital input (DI) pin of the main BMS interface. The first BMS interface P2 and the second BMS interface P4 also include XC1 and XC2 pins, connected in parallel to their respective digital input (DI) and digital output (DO) pins. A normally closed switch (which can be referred to as the first normally closed switch and the second normally closed switch) can be set between their respective XC1 and XC2 pins. When the first expanded battery module is connected to the first BMS interface P2, the first normally closed switch opens, and the BMS of the main battery module receives the connection signal of the first expanded battery module. When the second expanded battery module is connected to the second BMS interface P4, the second normally closed switch opens, and the BMS of the main battery module receives the connection signal of the second expanded battery module.

[0090] In one possible implementation, such as Figure 4 It also includes a first optocoupler module and a second optocoupler module;

[0093] In this embodiment, both the first and second optocoupler modules can be implemented based on conventional optocouplers to feed back the locking status of the electromagnetic locks on the first lock socket P3 and the second lock socket P5 to the main control module. The main control module can then feed back the locking status to an external terminal via a wireless module. The second operating voltage VCC2 can be 3.3V.

In specific implementation, when the first electromagnetic lock is in the unlocked state, the control input pin L1+ of the first lock socket P3 is at a low level. At this time, pins 1 and 2 of the first optocoupler U1 are connected, which in turn triggers the connection between pins 3 and 4, and the lock state LOCK1_STATE of the first electromagnetic lock is transmitted to the main control module in the form of a low level. When the first electromagnetic lock is in the locked state, the control input pin L1+ of the first lock socket P3 is at a high level.
