Electric Vehicles FAQ

What’s the difference between AC and DC electric vehicle chargers?

Difference between AC and DC chargers

As part of our retail offerings for large energy users, CS Energy has partnered with industry leaders Jet Charge and EVSE to offer a suite of low-cost, simple charging products that takes the hassle out of switching to electric vehicles for your organisation.

When considering a switch to an EV it’s important to consider the type of charging requirements of your business.

CS Energy offers two EV charging technology options for customers, based on their specific business needs.

The first is a direct current (DC) charger, which is what you will find at most fast-charging public facilities. DC chargers provide the fastest charging of EVs, which is particularly important when driving longer distances.

In 2020, CS Energy commissioned a DC charger at Kogan Creek Power Station for use by employees who drive EVs to the site, which is a four-hour drive from CS Energy’s corporate office in Brisbane.

The second is an alternating current (AC) charger, which are more commonly used in residential, fleet and inner-city locations. AC chargers are perfect for topping up your vehicle when you need to drive shorter distances, or for charging overnight.

Electric Vehicles FAQ

How far can you really go in an electric vehicle?


This year, CS Energy has installed 7kW and 22kW AC chargers at prime inner-city locations so Queensland Government fleet drivers can ‘top up’ their electric vehicles (EV).

In one hour, a 7kW charger adds enough power to drive a typical EV 50 kilometres, or from Brisbane’s CBD south to Yatala or north to Caboolture.  In the same period, a 22kW charger adds enough power to drive 160 kilometres dependent on the vehicle.

Queensland has had more than a thousand new electric vehicles registered in the past year as they become more popular and accessible.

EV uptake Australia wide is also gaining momentum as organisations move to upgrade fleets to position themselves for the future by reducing costs and their carbon footprint.
