Technology Certification Overview

  • Name of Technology : Restoring the low voltage of the battery solar power system control device technology
  • Certification Number : 0930 No. 2015. 08. Article 27
  • Patent : Solar charging control device and a control method
  • Overview of technology : As applied to the charge controller of the solar guard light control sheet,
    when the battery is low voltage, the solar power system is driven by a power outage Shut –down
    because of A self-regenerative (Wake-up) to recharge the battery to restore the normal system
  • Impact : In the past, it is impossible to regenerate battery without charging battery and replacement service directly.
    But, it is possible to solve unnecessary business trip and to save maintenance costs by solving these problems.

Problems of the prior art

  • In the commercialized solar charge controller configuration, main power is applied to control the battery voltage VCC level from low voltage to operating voltage.
  • When low voltage, the battery is disabled state because of controller poewr shortage
  • Battery is no regeneration even though it is possible to charge soloar power because charge control is impossible.
  • Especially, In case of Lion battery BMS(Battery Management System) cuts off the output when low voltage

Problems of the prior art

Configuration of the technology is

  • Main Micom performs original function like charge and discharge.
  • Sub Micom regenerates Main Micom(Wake-up) through low voltage switching due to keep an eye on battery.
  • MIJIENERTECH’s controller is consist of two parts. they are from battery to 1st regulator, Main Micom and from Solar Panel to 2nd regulator, Sub Micom.

Configuration of the technology is
