Smart Vehicle-to-Home (V2H) System for Electric Vehicles


The Smart Vehicle-to-Home System transforms Electric Vehicle (EV) batteries into energy storage devices for households. With the V2H system, electrical power stored in the EV batteries can be transferred to households in peak hours or when electricity is at a high price. It helps save electricity costs and alleviate the high electricity demand in peak hours.

Problem addressed

The growth of EV market has created huge demand for charging and huge load for power grid.

  • Electric Vehicle Power System (EVPS) controls the power flow among the Smart V2H System by implementing EVPOSSA V2H (EVPS-002)/ V2L (EVPS-004) protocol
    Renewable energy generation unit is included
Key impact
  • Save electricity cost when there is time variant tariff
  • Relieve the high demand in peak load hours
  • EVs can serve as emergency power sources
  • Energy storage devices for households
  • Emergency power source when power outages occur
  • Temporary power source for premises without power supply
Automotive Platforms and Application Systems (APAS)

Automotive Platforms and Application Systems (APAS) R&D Centre was established in 2006 by the Innovation and Technology Commission of HKSAR Government and hosted by the Hong Kong Productivity Council. The Centre undertakes R&D programmes as well as commercialising R&D results in collaboration with industry, universities and technology institutes for the development of the APAS technology. Since its establishment, APAS R&D Centre has carried out over 100 R&D projects and focus on 3 R&D areas, Green Transportation, Smart Mobility and Intelligent Systems. To facilitate greater synergy and further enhance cost effectiveness, APAS is form part of the Hong Kong Productivity Council with effect from 1 Nov 2012.
