Description

Technical Field

[0001] The present invention relates to the field of photovoltaic energy storage, and in particular to a method and system for low-power transportation, storage and awakening of energy storage batteries. Background Art

[0002] In the photovoltaic distributed energy storage mode, each photovoltaic panel is equipped with an energy storage battery stick (pack) to store part or all of the electricity generated by the photovoltaic panel during the day, and discharge it during the peak hours of the day, such as early morning and evening, or the peak hours of electricity consumption at night (8:00 to 10:00, 19:00 to 24:00). During other periods of the night, such as 0:00 to 5:00, the battery will neither charge nor discharge. At this time, the management system of the battery pack is still working and consuming electricity. In addition, after the battery pack is produced, the time to enter the storage and transportation stage may be as short as a few days, as long as several months or even years. During this process, the control board in the battery pack is still powered on and consumes electricity, so it is possible to completely exhaust the battery energy. The low-power transportation, storage and wake-up method of the energy storage stick is to deal with and solve the power consumption problem of the energy storage battery stick (pack) in this scenario. Summary of the invention

[0003] In view of the problems existing in the prior art, a low-power transportation, storage and wake-up method and system for an energy storage battery are provided to solve the power consumption problem of the energy storage battery during transportation, storage or long-term non-operation.

[0008] The battery control board automatically wakes up and receives a wireless broadcast at regular intervals. If no wake-up signal is received, it continues to enter sleep mode. If a wake-up signal is received, it exits sleep mode and enters working state.

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a schematic diagram of the low-power transportation storage and wake-up system of the energy storage battery proposed by the present invention. DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar modules or modules with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0024] In order to solve the power consumption problem of energy storage battery sticks (packs) during transportation, storage or long-term non-operation, the present invention proposes a low-power transportation, storage and wake-up method for energy storage batteries, wherein the energy storage battery includes a battery control board, and the wake-up control of the energy storage battery is mainly realized by the battery control board. The battery control board can exchange data with the gateway through wireless communication. The specific process is as follows:

[0025] Step 1: Before the energy storage battery leaves the factory, use wireless commands to put the battery control board into a low-power sleep mode to support long-term transportation or storage;

[0026] Step 2: In sleep mode, exit the sleep mode and enter the working state according to the wake-up signal of the wireless broadcast, or reset the battery control board by shaking with an external magnet and then enter the working state.

[0027] In this embodiment, a method of waking up the energy storage battery in sleep mode by a wake-up signal is provided. Specifically, in sleep mode, the battery control board automatically wakes up and receives a wireless broadcast every other end. If no wake-up signal is received, the battery control board continues to enter sleep mode. If a wake-up signal is received, the battery control board exits sleep mode and enters the working state. Among them, the wireless broadcast is generally a wireless wake-up signal sent by the gateway through continuous broadcasting, which can wake up the sleeping battery board within a few seconds, and the battery control board then exits sleep and enters the communication working mode.

[0028] In one embodiment, the panel can be set to wake up every 1 second or several seconds and receive wireless broadcasts.

[0029] Furthermore, for the energy storage battery in sleep mode, this embodiment also provides a wake-up method through magnet reset. Specifically, a reset pulse generating device is set at the reset pin of the battery control board, and the reset pulse generating device generates a reset pulse by shaking the external magnet, which is applied to the reset pin to control the battery control board to reset.

[0030] In one embodiment, in order to ensure reliable reset and reduce false triggering of other magnets, the battery control board counts the reset pulses received by the reset pin and resets only after receiving at least 3 reset pulses within 3 seconds. In a preferred embodiment, the reset pulse generating device is a reed switch or a Hall magnetic sensor.

[0031] Please refer to Figure 1 This embodiment also proposes a low-power transportation storage and wake-up system for energy storage batteries, including an energy storage battery, a battery control board connected to the energy storage battery, and a reset pulse generating device connected to the reset pin of the battery control board. The battery control board supports data interaction with the gateway through wireless communication, and the reset pulse generating device can provide a reset pulse according to the shaking of an external magnet.

[0032] In practical applications, the energy storage battery, battery control board and reset pulse generator are fully sealed to form an energy storage stick or energy storage package, which meets the IP68 waterproof requirement for long-term outdoor use. Only 2 input lines and 2 output lines are drawn out to connect the photovoltaic panels. When the battery stick (package) is working, wireless communication is used to exchange data with the gateway.

[0033] In order to reduce the power consumption of the battery stick (pack) during the required period, the control board of the battery pack can enter the low power consumption mode through wireless commands. After entering the low power consumption mode, the power consumption of the entire control board is only tens of microamperes. In the low power consumption mode, the battery power supply can be maintained for several years or even decades. In fact, the energy storage battery stick (pack) will not be used directly after production is completed, but will be used after long-term storage or transportation. Therefore, in this embodiment, the energy storage battery stick (pack) enters the low-power sleep mode of the battery control board through wireless commands before leaving the factory, and wakes up when it needs to work.

[0034] For the energy storage battery stick (pack) in low-power sleep mode, two wake-up methods are provided: gateway wireless wake-up and magnet reset wake-up.

[0035] (1) Gateway wireless wake-up

[0036] The battery control board in sleep mode automatically wakes up and receives wireless broadcasts at regular intervals. If no wake-up signal is received, it continues to enter sleep mode. If a wake-up signal is received, it exits sleep mode and enters working state. The interval time can be set according to needs, such as 1 second or several seconds. During the wake-up process, the gateway can wake up the sleeping battery board within a few seconds by continuously broadcasting wireless wake-up signals, and the battery control board will then exit sleep and enter communication working mode.

[0037] (2) Magnet reset wakeup

[0038] By shaking the outside of the energy storage battery stick (pack) with a magnet, the internal reset pulse generating device generates a reset pulse, which is applied to the reset pin to control the battery control board to reset.

[0039] In order to ensure reliable reset and reduce false triggering of other magnets, the battery control board also includes a reset pulse counting unit for counting the reset pulses received by the reset pin; the battery control board resets after receiving at least 3 reset pulses within 3s.

[0040] In one embodiment, the reset pulse generating device is a reed switch or a Hall magnetic sensor.

[0041] In order to indicate the reset wake-up position of the magnet, a wake-up area is set on the outer surface of the energy storage battery stick (pack); the wake-up area is close to the position of the internal reset pulse generating device, so that the external magnet can quickly interact with the reset pulse generating device when shaking.

[0042] The energy storage battery low-power transportation storage and wake-up system proposed in this embodiment can be applied to each battery stick (package) of a photovoltaic distributed energy storage project. The battery stick is set to a sleep state through wireless settings when leaving the factory, and there is no need to worry about the length of storage and transportation time. When the battery stick is installed, a magnet can be used once on site to activate the working state of the battery stick. After 12 o'clock in the evening, a sleep broadcast is sent uniformly through the gateway to put tens of thousands of battery sticks into a sleep low-power state. At 7 o'clock in the morning, the gateway sends an activation broadcast again to make all battery sticks exit sleep and enter a working state.
