Just my humble opinion, but I feel that it is always better for the condo board to institute a comprehensive Electric Vehicle Infrastructure Plan. Having owners one-off installations will severely restrict the ability for others to install a EV charger in the future. A plan will specify the amperage that each charger can use (24 amp, 30 amp breaker is more than enough, this gives about 32km/hr charging). Also the gov'ts ZEVIP program will pay 50% of the total cost! Electrical contractors will sell you their system that includes meter reading etc which is both complicated and expensive. Just for comparison, we installed 2 panels each with the availability to feed 21 chargers (42 in total) with a load sharing and usage reporting panel. We had 14 chargers installed even though we only had 2 ev's at the time. That was a year ago, since then we have had 2 more installs and have 5 ev's total. Most of the others did the install because the price was great, or because they are planning to get an EV in the future, or to increase the value of their condo. The installs, including the infrastructure was done with zero cost to owners not participating, or those that did not have a parking spot. The hydro is billed back to the EV owner with zero markup every 3 months. My bill for the last 12 months came to $246. The cost of the installs including all costs, ESA inspections, share of the infrastructure cost and all taxes was between $2902 and $3405.
Full disclosure, I am on my buildings board of directors. I have installed a charger in my last 3 condos over the last 9 years. I also now consult with board of directors specifically with regard to Electrical Vehicle Infrastructure planning.
