EV charging and EV lithium battery fires are two issues that are still evolving.
In regards to EV charging, the vast majority of EV owners can charge their EV battery using a standard 10amp power point; eg 10 hours of charge will provide over 120km (https://evse.com.au/ev-car-guide/tesla/tesla-model-3/). The exceptions will be sales reps and tradies that tend average greater distances. Is anyone struggling to keep their car charged to 80% off a 10amp power point?
The next issue is the power available to the property. Cities will never have have unlimited supply as the cost of the infrastructure is too high. So the solution is demand management which all of the commercial car charging networks utilise. Owners corporations can also install demand management to make sure their building does not exceed the agreed maximum supply current from their utility company. But it will cost to make the initial investment.
The issue of fires is something that at this point in time is unresolved. It may only come up as an issue if the OC applies for a building permit for the installation of car chargers. I have been advised by a building surveyor that car charging of EVs is considered an additional level of hazard that in turn needs an additional level of fire mitigation. Have any other OC’s come across this? Or are EV chargers being installed without a building permit? If that is the case, is that jeopardizing insurance cover?
IMHO it is up to the EV manufacturers to bring down the risk and flammability of the batteries that they are installing to levels that the authorities agree is no greater that ICE vehicles. In turn it is up to governments and regulators to bring in battery flammability standards as they have with vehicle crashes and passenger safety.
