INTRODUCTION1 1 PrefaceThe coming years will see more and more ELECTRIC vehicles on Canadian roads. Since 2011, when plug-in vehicles* became available in Qu bec, sales have doubled each year. Though all of these vehicles can be charged from an ordinary 120-V outlet, charge time can be short-ened with a 240-V CHARGING station or a D C fast-charge 2 Purpose of this GuideThis Guide, written for master electricians, retailers, municipalities and the general public, presents the basics of installing E V CHARGING 3 ELECTRIC vehiclesSection 86 of the Qu bec Construction Code, Chapter V Electricity (the Code) defines the ELECTRIC VEHICLE as an automotive-type VEHICLE for highway use that includes passenger automo-biles, buses, trucks, vans, low speed vehicles, etc.

10 , powered by an ELECTRIC motor(s) that draws current from a rechargeable storage battery, fuel cell, photovoltaic array, or other source of ELECTRIC current [..]. 1 This Guide uses the above definition of ELECTRIC VEHICLE (E V), but limits the scope to passen-ger vehicles that draw current from a rechargeable storage battery. There are four types of E V: hybrid ELECTRIC vehicles (H E V), plug-in hybrids (P H E V), battery ELECTRIC vehicles (B E V) and ex-tended range ELECTRIC vehicles (E R E V). Hybrid ELECTRIC vehicles H E V s have two motors: an internal combustion engine and an ELECTRIC motor. Their storage batteries are generally low-capacity, which greatly limits their range and top speed in ELECTRIC mode. They cannot be recharged from the grid and are therefore not covered by this Guide. Examples: Toyota Prius and Honda C Plug-in hybridsP H E Vs are hybrids that can be plugged into the power grid for battery CHARGING .
