EV Chargers are divided into three basic categories:
Level 1 – 120V 15-20A 1kW-1.5kW
Level 2 – 240V 30-80 7kW-19.2kW
Level 3 (DC chargers) – 480-600V 50kW-400kW
Most single-family developments (SFD) can accommodate a level 1 charger through any dedicated general receptacle. If an extension cord is required, it must be of sufficient size for full load and must be as short as possible to reduce voltage drop. For short trips a level 1 system can keep your car charged sufficiently. If you do the occasional driving that requires your full charge you can visit a level 3 commercial facility to get you fully charged quickly.
If you drive quite a bit a level 2 system would be a best option. The bigger the unit, the quicker the charge. If you have only one EV to charge, it may not matter but if you have two EVs or one EV and one PHEV a larger (quicker) system would be beneficial.
A level 2 system will require some load management and system engineering to work with the capacity your system has available currently.
Once you determine your charging needs you will require a professional to implement your needs to your electrical system.
If possible, load management devices should be avoided as they create a priority load sharing situation. A knowledgeable technician will be able through BC Hydro demand studies and existing system strategies to accommodate your needs.
Not all situations and strategies are the same as some electricians have been known to upsell to the biggest and to gain economically.
Level 3 systems require industrial voltages and capacities, not possible for single-family developments or light commercial. Some high-rise multi-unit residential buildings (MURB) could facilitate this approach if they implement in initial design or an existing tower could do additional upgrades to accommodate. Level 3 could only be utilized in small numbers as the demand is immense.
The execution of an EV Ready Plan will allow stratas the ability to forecast the degree, infrastructure and budgets to facilitate effective EV charging.
There are many unique situations in the world of stratas with the probability of a common solution unlikely.
Technical expertise and experience can be extremely helpful when trying to create an economic solution.
