Support Frequently Asked Questions

Prevent local network disruptions

Load management can prevent overloading of essential devices and minimise the wear & tear of circuitry by ensuring the network of EV chargers never overdraw from the power distribution system they are connected to.

Improve existing electrical infrastructure

Can operate additional EV Chargers to a DB network without upgrading existing electrical infrastructure i.e., distribution boards, wiring etc.

Reduce associated power costs

Load management can allow for scheduling charging times outside of peak loading periods, avoiding the rates associated with electricity usage during peak hours.

Charging speed depends greatly on the vehicle’s battery design. However, the average charging speed with DC chargers:

  • 60kW=300-400 km/hr
  • 90kW=500-600km/hr
  • 120kW=650-800km/hr
  • 150kW=850-1000km/hr

EVs can draw up only a certain kW. It depends on the car itself, most of the cars available today are only drawing up to 11kW but the EV chargers we have can be up to 22kW for future purposes.

Yes, you can use the cables on the charging stations interchangeably though you would be limited by the max speed of your cable.

AC charging utilises the on-board AC to DC power converter that is connected to your EV battery to charge your car. AC EV chargers require an adapter connection to a distribution board in order to charge your car

  • Available in single-phase and 3-phase charging
  • More cost-effective solutions

DC Charging performs AC to DC power conversion outside of the EV.

  • Units are much larger due to housing a much larger AC-DC power converter than the converter in your car
  • Greater charging range and capacity (20kWh-150kWh)
  • Charging times are much faster than AC charging
  • DC Charging leads connect directly to your battery
  • A Tethered charger has a permanently attached charging cable. Whereas a Universal charger will require a detached charging cable (sold separately).
  • A tethered charger has a fixed-length cable of 6 meters. The length of this cable can not be adjusted.

.

The main difference between 7kW and 22kW is the charging speeds and how many lines of power are routed to each.

7kW is our single phase charger. It charges slower than 22kW but most homes will require this charger due to the power available through the switchboard. 

22kW is our three phase charger. Three phase chargers have the capability to charge at a faster rate than the single phase, however installing in the home is not available to everyone as this requires existing three-phase power setup. The design of the vehicle will determine how much power can be drawn from the charger regardless of how fast the AC charger is.

  • Your charger may be downrated to a lower kW
  • Your car may have a lower charging rate
  • Your charging cable may not be 22k

Even if the customer is not using a smart charger, the car will be the one to disengage internally to stop the battery from overcharging. It will not draw anymore power from the EV charger and will only stay idle until the user manually removes the cable from the car.
