DC CHARGING

When to choose DC Charging

DC charging is normally provided where vehicles need to charge to 80% in 30 minutes or less

  • Intercity charging at freeway service stations
  • Destination charging in town centers
  • Depot charging for buses and commercial vehicles that require fast charging during the day
  • Overhead pentagraph charging at bus stops
  • Locations where a fast top-up may be required are apartment blocks, commercial developments, motor vehicle dealerships, taxi companies and places the vehicles exceed their maximum range during the day

DC Charging Power

DC charging stations can deliver power at a rate of between 22 kW and 350 kW. Most electric vehicles on the road draw at less than 100 kW. A vehicle with a maximum draw of 80 kW will not utilise the full capacity of a DC charging station.

  • Open Charge Point Protocol (OCPP) 1.6+ compatible. The station should be directly connectable to any OCPP compatible network management system. Some stations on the market can only be connected to the manufacturer’s network. OCPP connectivity is provided through a gateway on the manufacturer’s network. This is a security risk because the charging station provider has no control over the gateway side of the network and cannot install IOT intrusion detection devices on the manufacturer’s network.
  • Modular. Expandable from at least 50 kW to 350 kW or somewhere in between. Initial capital costs can be reduced by installing a 50 kW station and avoiding expensive grid upgrades. The station can be upgraded at a later stage when it becomes economically feasible.
  • Compatible with CHAdeMO and Combo CCS to facilitate both charging standards.
  • Max output voltage: CCS 2 920VDC, CHAdeMO 500VDC.
  • Max output current: CCS 2 350A, CHAdeMO 200A.
  • On-board load balancing so that two cars can be charged at the same time, one on CHAdeMO and one on CCS.
  • Facility to dial down the power output of the charging station
  • Power module failover. Remaining modules keep charging if one module fails.
  • Easy to install.
  • LCD screen for messaging and instructions. Should be daylight readable.
