Company profile
researched Aug 2026GloquadTech Co., Ltd. is a South Korean company that develops charging communication technology for electric vehicles and mobility. Its product range covers EVCC (Electric Vehicle Communication Controller), SECC (Supply Equipment Communication Controller) and IMD units, together with power line communication (PLC) modems for AC chargers (GQSE8823K), DC chargers (GQSE8821K) and vehicles (GQEVPLC). The company's charging communication solutions support international standards including DIN70121, ISO15118 (including ISO15118-2 with Plug and Charge and ISO15118-20), IEC61851-1, CHAdeMO, GB/T27930 and NACS, and its EVCC line supports ISO21434 cybersecurity as well as the VDV261 commercial-vehicle VAS standard.
Alongside components, GloquadTech sells development and validation tools: the GQ-SDK software development kit for battery pack BMS and charger controller charging communication; the GQ-Charger Tester, an all-in-one EV charging test unit supporting DIN70121, ISO15118 and CHAdeMO charging sequence tests plus insulation resistance testing; and the GQ-EVSIM EV simulator, which supports CCS Type-1, CCS Type-2 or CHAdeMO inlets, charge testing up to 1000V and 200A, communication monitoring for debugging, and use as end-of-line production test equipment.
The company began developing PLC modems for EV chargers in 2012 and commercialized Korea's first PLC modem for DC chargers in 2014. It also states it developed and commercialized a CCS-standard SECC for the first time in the Korean industry in 2014, and later developed ISO15118-2 PnC-capable SECC applied in the North American and Korean markets. GloquadTech contributed to the first DIN70121-compliant EV charger project in Korea and participates in the expert group for electric vehicle standardization in Korea.
Business model
GloquadTech develops and produces EV charging communication hardware and software — SECC and EVCC controllers, PLC modems, IMD and simulation/test equipment — and sells them to EV OEMs and EV charger (EVSE) manufacturers, including customized variants where modem specifications are adapted to customer requirements. It also supplies production inspection equipment used for subsidy-related testing and certification in Korea.
Traction
Supplies SECC to the Korean market under Ministry of Environment smart control charging communication requirements and EVCC to global EV OEMs; states more than ten years of product verification in over 60 countries; holds Automotive SPICE CL2 certification; credited with 7 patents; CharIN member since 2020-01-01.
Latest developments
In February 2025 the company announced it would supply SECC supporting smart control charging communication standards along with production inspection equipment for subsidy-related testing and certification. It exhibited charging technology at Africa E-Mobility Week 2025 in Addis Ababa (15-16 October 2025), and in November 2025 published news of Automotive SPICE CL2 certification and an interview with CEO Bryan K.S Chang on its global expansion plans. Other announced items include an ISO 21434-based cyber-security EVCC for global OEMs and an EV charging solution for apartment buildings.
