The Board of Directors at my Condominium building decided to install a Level 2 electrical vehicle charger station into the garage in a public parking spot. It has a long term goal to put more of them into owner parking spots later upon demand.
Electric cars (EV's) and plug-in hybrid vehicles are becoming popular as many drivers are attracted by their “green” labels. Even though they are proven to be carrying a larger carbon footprint than diesel vehicles of the same class (subject to the level of fossil fuel generated electricity they use), many are not aware of this study. This topic was discussed under one of my earlier articles : http://chinesenewsgroup.com/news/666626.
The validity for the statement above is determined by the power generating stations using 60% or more of carbon fuels. In Ontario, less than 10% of electric power generation currently involved the use of carbon fuels (natural gas). It is therefore safe to say that the use of electric vehicles in Ontario does help to reduce the emission of carbon gases.
Condominiums are facing difficulties when it comes to the installation of Electric Vehicle Chargers (EV Chargers). Many older buildings do not have the electrical transformer capacities to accommodate the extra electrical demands from these devices. Corrections to these deficiencies can involve large sums in procuring electrical equipment and facilities for their placements that may not be available to the Condominium corporations. In the end, only a limited number of devices can be made available to owners on a first come, first serve basis.
As a director serving on the Condominium Board, I was involved in the research and procurement of our first EV Chargers. My knowledge base increased now to include the various types of EV Chargers and their functions:
Level 1 (L1) Charging Stations - The charger is included with the car at the time of purchase. These chargers can be plugged with one end into any standard 120V outlet, with the other end being plugged directly into the car. It can charge 200 kilometres (124 miles) in 20 hours.
Level 2 (L2) Charging Stations - These chargers are sold separately from the car, although they’re often purchased at the same time. They require a slightly more complicated setup, as they are plugged into a 240V outlet which allows charging 3 to 7 times faster depending on the electric car and the charger. All of these chargers have an SAE J1772 connector and usually have to be installed by an electrician. It takes around four hours to fully charge a 30-kWh battery car (standard battery for an electric car), which allows you to make the most out of driving your EV, especially when you have a limited time to charge.
Level 3 (L3) Charging Stations - also called Direct Current Fast Chargers (DCFC) are much more powerful than level 1 and 2 stations, meaning you can charge an EV much faster with them. that being said, some vehicles cannot charge at level 3 chargers. It is necessary to do your homework on the model you want to purchase. The Level 3 Charger is very expensive (can be up to $50,000) but also very fast. It can charge up to 80% of a 400 Kilometre range battery in about one hour.
购买什么样的电动汽车需要做功课，并考虑所要使用的充电器，还要考虑行车的路途中可否充电。电动汽车附带的连线将是首要考虑因素。如果你有充电器却因无法连线，那是非常懊恼的事！加拿大和美国的所有电动汽车都可以使用SAE J1772 EV插头充电，但特斯拉电动汽车除外。特斯拉拥有自己的连接器，但你可以用适配器。 J1772连接器仅可用于1级和2级充电。
Buying the proper Electric Vehicle involves doing your homework and planning which charger(s) you will be using and available to you on your regularly travelled routes. The connector coming with your Electric Vehicle will be a top consideration, it will be very frustrating if you pull up to a charger and cannot use it! All electric cars in Canada and in the US can charge using the SAE J1772 EV plug and Tesla cars come with such an adapter in addition to its own connector. The J1772 connector is only available for level 1 and 2 charging.
对于3级充电器快速充电，“ CHArge de MOve”（CHAdeMO）和SAE Combo（也称CCS）是电动汽车制造商最常用的连接器。这两个连接器不可互换，这意味着具有CHAdeMO端口的汽车无法使用SAE Combo插头充电，反之亦然。这有点像汽油车无法用柴油泵加油。
For fast charging with Level 3 Chargers, the “CHArge de MOve” (CHAdeMO) and SAE Combo (also called CCS for “Combo Charging System”) are the most used connectors by electric cars manufacturers. These two connectors are not interchangeable, meaning a car with a CHAdeMO port cannot charge using an SAE Combo plug and vice versa. It’s kind of like a gas vehicle that can’t fill up at a diesel pump.
Tesla vehicles are in a category of its own. Their connector is used on level 2 and level 3 Supercharger Tesla charging stations and are only compatible with Tesla cars. However, Tesla's come with adapters for both the J1772 connections and CHAdeMO connections.
Choosing an electric vehicle is a very complicated matter. A better “green” choice may be the “plug-in hybrids” - vehicles that use gasoline yet allowing for electrical charging at Charging Stations to optimize the use of “Green energies”. These vehicles will not leave you stranded while looking for a charging station. They will cut over to gasoline fuel once the electrical charge is exhausted. They will be the subject of my next article as I am currently exploring the market to find my next “green” vehicle.
