BSS Station

  • High efficiency duplex fast charger(charging efficiency over 95%) with B2G technology that can backfeed electricity from charged battery to electrical grid
  • Energy demand management technology that links Electric bus battery and B2G technology
  • Power Conditioning System(PCS) technology for ESS that can use new and renewable energy

Battery Swapping Process and Technology of Device

Automatic battery swapping technology includes BSS station that links swapping control robot, vision system,
fast charger and etc. which automatically swaps discharged battery into charged battery

Electricity demand management using BSS station

  • 1. Linking used battery reusing business and Demand Response(DR) business to create profit and expanding business by re-investment
  • 2. By electricity demand contract of possible reducement and with instruction of Power Exchange, contracted electricity may be sold when needed by linking energy demand management business and DR business.

Storing electricity in BSS station battery / Reusing electric bus used battery Linking DR business

  • Using as ESS when Electric bus ends operating
  • Transmitting electricity from charged battery in BSS station to electrical grid
  • By contracting with DR company, Battery to Grid(B2G) technology that can perform energy demand management through duplex
    Power Conditioning System(PCS) in BSS station
  • Using demand management by charging battery at midnight with low price and supplying electricity at peak time
