Hybrid Energy-independent Smart Streetlights Utilizing Recycled Waste Batteries from EVs


[INQ. NO. 2208E01] This hybrid smart streetlight is an energy-independent system that recycles waste batteries from electric vehicles. The three “no’s” (no communication expenses, no electricity bills, and no power lines) are features of the system, which applies the color temperature variable LED for the safety of drivers and the energy-independent private network.

In particular, the system uses a 100% wideband private communication network (Sub-G + WiFi Halow + TVWS) as the key communication infrastructure needed for building a smart city. The streetlight can control color temperature (2,700~6,000K) through a variety of open APIs and visibility data for the safety of citizens, including drivers. This differentiated and original system is supplied to countries that frequently experience bad weather conditions due to topographical features.

The technology of recycling waste batteries from electric vehicles uses electrochemical impedance analysis to diagnose batteries most accurately and quickly with life-prediction and quality-inspection algorithms, thereby contributing to the recycling of waste batteries as part of the energy-independent smart streetlight system.

Life-prediction and quality-inspection algorithm S/W and GUI design applied to the hybrid system (patent application)

Development of the Waste Battery Inspection System

The waste battery diagnosis system using EIS (electrochemical impedance spectroscopy) can predict lifespan and perform quality-inspection of batteries.

The system applies the most efficient measurement method in order to provide accurate diagnosis parameters and thus recycle waste batteries for hybrid smart streetlights. They can improve the price competitiveness of batteries and introduce eco-friendly energy systems so as to resolve energy shortages in cities, optimized for global low-carbon energy campaigns.

In particular, this new technology applies a high-precision booster designed for waste batteries and the main acquisition system. It provides quality inspection and life prediction algorithms through SOC measurement of waste batteries (21700), SOC-SOH relation analysis, impedance measurement (EIS) of waste batteries (21700), and development of the Nyquist Plot database.

This can contribute to resolving energy shortages in cities through battery life prediction, database management, and GUI in alignment with the control server of the hybrid system.
CN WIDERS Co., Ltd. is planning to expand the market for the new technology by actively promoting these advantages.

AWS/ITS-based Color Temperature Variable Smart Streetlights with AI for Improving Visibility

Based on the AWS (Automatic Weather System) and ITS (Intelligent Transport Systems), this system offers AI functionality to improve visibility for drivers and controls the color temperature (2,700~6,000K).

The control server considers open weather API, weather conditions (heavy rain, heavy snow, fog, etc.) and measurements of visibility meters installed in the field in order to control the color temperature (2700K~6000K) of the smart streetlights.

This can help to improve visibility for drivers and thus to prevent accidents caused by bad weather conditions. The visibility meter is aligned with weather data (heavy rain, heavy snow, fog, etc.) collected via open weather API (Application Programming Interface), and the color temperature is adjusted 2,700~6,000K) according to the weather conditions to enhance visibility for drivers. The message delivery algorithm is used to communicate dangerous road conditions through the street lights.

And the 24Ghz/60Ghz-band radar detects objects in conjunction with the server, and can send an alert to drivers to protect animals and drivers in accident-prone areas and wildlife protection areas.

Digital Signage & Additional Services via the Private Wide-Area Network of the Smart Streetlight

This system provides public information (reports on road and weather conditions and environmental data collected via radar) and various additional services through digital displays – with the relay using a multi-band and multi-channel private wide area network without network maintenance or communication costs.

This system of ICT convergence and communication technology can be utilized as a key element for building a smart city. The smart streetlight offers a variety of information via digital signage without communication fees by using a private network that combines Wi-Fi HaLow, TVWS, and G-Sub communication technologies.

Medical Equipment


[INQ. NO. 2207E03] KOIBIG Co., a medical device development and manufacturing company, has recently developed ‘Pain Block’ for non-surgical pain relief, which applies advanced NeuroScience Medical technology that is safe for the human body, and secured intellectual property rights.

The ‘Pain Block’ medical device developed by KOIBIG Co. is new medical technology that attaches electrodes in pain-producing locations. When the device is operated, it generates a painless signal with a smooth but strong output, which causes the patient to perceive the pain signal as painless.

Based on this, KOIBIG Co. received an item authorization from the Ministry of Food and Drug Safety (MFDS) for non-payment code MZ012 non-invasive painless signal therapy, and completed the ISO 13485 certification to make inroads into the global market. In 2020, it succeeded in exporting to Indonesia, and currently, China, Vietnam, Taiwan, and countries in Southeast Asia are also interested in exporting and certification through export branching projects.

In Korea, more than 500,000 patients are suffering from cancer pain, diabetic peripheral neuropathy, complex area pain syndrome, and neurological disorder after shingles; and they have difficulty in even normal social activities due to constant pain and frequent use of painkillers, leading to an uncontrollable vicious cycle of pain.

In particular, about 35 percent of these pain patients even feel suicidal due to insomnia and depression, and as the pain-level is grows higher they often have to rely on drug painkillers. These can have many side effects and cause severe pain. By inserting an implantable drug injector into the body to control pain, a decrease in the pain index results during ten treatments over two weeks with a ‘Pain Block’ medical device without relying on such surgery or drugs.

KOIBIG Co.’s corporate research center has developed a skincare device using the latest plasma technology and a cooling ultrasound device and will continue to introduce new products.

With the acquisition of KC certification for beauty devices, the interest of distribution-related workers and skin-related workers is increasing, and it is growing as a unicorn company in the future.
