EV Charger Installation in Central Geelong

On a tight 3220 allotment built to the street and both side boundaries there is no side path to run a cable down. Parking is a basement or podium space, a rear laneway hardstand, or an on-street permit bay. Only the first two can take a fixed charger at all, and the third is worth saying out loud because nobody else will.

Where the space is in a basement, the run goes from a house board or your own meter position through the building riser to the space. That is usually the largest line on the quote and it is measured in metres of cable tray and conduit, not in charger brand. We walk it before we price it.

In most of the region we spend the phase conversation talking people out of it, because residential streets are single phase and a conversion costs more than it returns. Central Geelong is the exception. Commercial and mixed-use buildings here are overwhelmingly three phase, and a lot of the apartment stock has three phase to the house board even where individual apartments do not.

Where three phase is already at the board and your car can use it, a 22kW capable unit is a legitimate spend at $2,500 to $3,000 plus rather than a vanity purchase. Where the supply exists in the building but your tenancy is fed single phase, the honest answer is usually a 7.4kW unit at 32A, which still adds roughly 40 to 50km of range an hour.

Mixed-use buildings in the city core frequently have metering shared or banked across tenancies, and the board feeding a car park is often not the board feeding your apartment or office. That matters because whoever is billed for the electricity has to be the same entity that agreed to the installation.

If the charger, the cable route or the space itself sits on common property, you need written owners corporation consent before anyone installs anything. This is not a reason to give up, it is a step. We produce the scope, the load figures and the route drawing that a committee actually needs to say yes.

Buildings in the city core were not designed with a car park full of chargers in mind. Adding one 32A load to a building already running lifts, air conditioning plant and a dozen tenancies can be fine. Adding six is often not, and the constraint shows up at the main switch rather than at your unit.

A load management device at $200 to $600 monitors total demand and throttles the charger instead of tripping the supply. In a multi-unit building, dynamic load sharing across several chargers is the standard answer, and it is far cheaper than the alternative of upgrading the building supply. Powercor can require it where the incoming capacity is constrained.

Waterfront buildings on Corio Bay carry genuine marine salt exposure, and it is the fixings, gland plates and the isolator beside the charger that go first rather than the sealed unit itself. In an underground car park none of that applies. On an exposed podium deck facing the bay it very much does, and we use stainless fixings and coastal rated glands there as standard.

Every EV charger install is prescribed electrical work. The charger gets its own final subcircuit back to the board, cable sized for a continuous load, a correctly rated breaker and RCD protection suited to DC leakage under AS/NZS 3000. There is no compliant version that shares a circuit with power points.
