Using rapid commercial EV chargers are great in some instances. However using rapid chargers too often can lead to a decline in your EV’s battery life. Not to mention the convenience of charging your EV in your own garage.

An EV’s capacity ranges from around 50kWh to 90kWh, this means the cost to charge an EV in Australia ranges from $12-$25 (on peak tariff) and $7-$15 (off peak tariff) 0%-100% charge.

A common way to save on electricity costs is to charge your EV during off-peak times (10pm to 7am).

It is recommended to keep your battery above 20% and to charge it up-to 80%. This will prolong the life of your EV’s battery.

This can vary depending on the speed of charging you require. Old houses might only have 32-40A Maximum capacity for the whole house. Where as newer houses 2000 onwards might have 63a to 150a capacity available.

Most older Australian homes (pre 1990) have single phase mains connections with a maximum capacity of 40A (or less!) for this EVergize may suggest 16A single phase charging. In some cases the old mains wiring is in poor condition and may need to be upgraded to either Single phase 63A or even three phase 50A which would allow faster charging and heavily reduce fire (and other) risks in your home. EVergize Is happy to advise on mains cabling should it need to be looked at.

If you do have old style ‘fuses’ in your main switchboard we highly recommend you get your switchboard upgraded regardless. If this is the case it is also likely you need to upgrade your “mains” cable to accomodate efficient charging.

Have a look inside your main switchboard. If there is a switch labelled ‘Main Switch’ looks like the width of 3 circuits in 1 then its likely 3 phase. If your main switch has the width of only a single standard circuit (like the others) its probably single phase.

EVergize does not recommend (in most cases) using a regular socket outlet for charing your EV. Regular sockets are shared with other appliances in the home and may impact their operation. A stand alone charger uses its own circuit.

15A sockets can charge at a rate of 3.5kw per hour. This means an EV with a small capacity (54kWh eg. Model 3) would take around 15hrs to charge 0-100%. Commonly 15A sockets have their own circuit to not interrupt other appliances in the home. A dedicated 15a socket may be a good option for some EV owners.
