Electric vehicle charging

• 

  Electric Vehicle Supply Equipment (EVSE), often referred to as Electric Vehicle Charging Stations, is equipment that delivers electrical energy, from an electricity source, to charge an EV battery. The EVSE communicates with the EV to ensure a safe supply of electricity.
  Understand the basics for charging an EV:
  The electricity grid delivers AC (alternating current) but EVs charge their batteries with DC (direct current).
  1. An electric vehicle has an onboard charger to convert AC power to DC.
  Buying a charger: The supply and commissioning of Electric Vehicle Supply Equipment (EVSE) involves:
  1. the distribution of EVSE and electrical hardware
  2. the installation of the hardware including civil and electrical design and labour
  3. management software provision and installation
  4. connection to a network
  Installing a charger: There are three contributing costs associated with the installation of Electric Vehicle Supply Equipment (EVSE) on a site:
  1. Electrical infrastructure
  2. Civil infrastructure
  3. Site safety
  1. The cost of a site is driven by the complexity of the installation tasks along with the cost of the actual EVSE unit itself.
  2. There are a number of strategies that can be employed to minimise costs.
  Charger installation projects: The key roles required in a charger installation project include:
  1. electrical upgrades
  2. civil works
  3. charging station implementation and testing
  4. communications systems implementation and testing
  5. billing system implementation and testing (if required)
  6. warranties, service and support for charging issues
  7. warranties, service and support for the billing system
  8. warranties for electrical installation
  Charger operating basics: A charger operator is responsible for mediating the interaction between the driver and the charging station. This role can be performed by the site owner/manager (commonly referred to as the host) or it can be outsourced to a third party service provider.
