Ontario is investing 20 million in public charging and I commend them for it. They should be promoting vehicles that can take full advantage of the coming network, but there are several vehicles getting the full $13,000 that cannot.
In lieu of or in addition to the bonus for 5 seats (or 4.5 seats in the case of the 2016-Volt) there should be a bonus for a quick charge port. The stated rational for the 5-seat bonus is that it makes cars more practical--which is exactly what quick charge does for EVs.
There should be a $1,000 penalty for plug-ins that don't have a level II on board charger of at least 6 kW. Then if an upgrade from 3.3 kW were a $1,000 option, everyone would order it. If a PHEV has a Winter AER of less than 50 km, one hour L2 charging at 6 kW while out and about might often make the difference between burning gas or not. However, 3 kW usually means too slow to make a difference or a vehicle clogging up a station for twice as long. On top of that, if the station charges a flat or hourly fee some PHEV drivers will rather pollute than charge, because at < 4 kW they feel electricity costs more than gas.
The budget for this program is obviously not infinite, so to allow as many citizens as possible to benefit, I would cap the rebate at $10,000. PHEVs not having a battery of at least 10 kWh should be limited to $4,000. The increased rebates would not be retroactive. There is no way you can create more November 2015 sales, so can anyone explain why people who purchased then will be getting checks for up to $4,500 additional? In order to qualify for the full rebate on leases, the minimum term dropped from four years to three? Why?
Finally, any restrictions on rebates for supposedly rich drivers would be based on income and not on MSRP. It's crazy that a family that has two 50k EVs, trades them in every three years and vacations every year in the Caribbean might get $52,000 off over the next 3-4 years, but a family that goes with a single Tesla and prefers tent-camping vacations only gets $3,000.
