Solar double-battery switching device and switching method

Abstract

The invention relates to a solar double-battery switching device and switching method. The device includes a controller, a micro stepping motor, a permanent magnet, a first reed switch, a second reedswitch, a charge and discharge reed switch, a solar power generation assembly, a linkage switch, a first battery pack and a second battery pack. A micro stepping motor solution replaces a relay solution, so a problem of large power consumption of a coil is solved. The device is advantaged in that a PMOS switch solution is replaced, a problem of power supply incapability when a port of a PMOS switch is reset and released during dormancy of a single-chip microcomputer is solved, a controller can be in a dormancy state, and the port of the control stepping motor can be reset and released. When the micro stepping motor starts switching only when a voltage of the battery pack is low, power consumption is low, low power consumption is achieved, automatic switching based on a current power supplyvoltage value and a current charging voltage value of the battery pack can be performed, the current position information of the reed switches can be acquired by the controller in real time, and accurate switching is guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar double battery switching device and a switching method. Background technique [0002] A floating body that drifts with the current in the sea is dropped by a ship or an aircraft. It is composed of floating body, sensor, data transmission, system control, power supply, data quality control and other systems. [0003] The power of the solar panel is very small, which can only meet the power supply of a group of batteries, and it can discharge the load while charging, and it is difficult for the battery to achieve floating charging. [0004] Of course, some devices are currently equipped with two sets of lithium batteries. Two sets of lithium batteries can solve the problem of charging and discharging the load at the same time. It is difficult for the battery to achieve floating charging. The charging process, but it needs to be switched by a relay. The power consumpt...

AI Technical Summary

Problems solved by technology

[0006] Replacing relays with PMOS tubes can achieve the purpose of saving power and energy, and the control can also be completed. However, when the MCU controller enters low-power sleep, the control port is reset and released, and the power supply of both groups is cut off, so the power supply cannot be guaranteed.
