They are called chargers, but in fact are only supply units that provide power and some first level diagnostics for your electric or hybrid vehicle. The charger is actually on board the vehicle and regulates the amount of power supplied to the batteries.


Level I supply units provide charging through a 120 volt, alternating-current (AC) plug and does not require a dedicated circuit. Level 1 charging can be used in a standard 15A duplex receptacle (as seen in your house). Level 1 charging equipment does not require the installation of charging equipment. The unit will come with a cord set you can plug into any household 15A receptacle. On the other end is a J1772 connector, which plugs into the vehicle.

Depending on the battery technology used in the vehicle, Level 1 charging can takes up to 20 hours to completely charge a fully depleted battery (dependent on battery bank size) providing approximately 1.2kw output (12A @ 120V). This would be considered a secondary form of vehicle charging. Primary charging should be provided with a Level II supply unit.


Level II supply units offer charging through single phase 240V, AC and 3 phase 208V AC. These units require a dedicated 2 pole 40A / 3P 40A breaker to feed the required 30A output or approximately 7.2kw. All certified Level II supply units are compatible with electric vehicles and plug-in electric hybrids manufactured in North America.

Level II chargers have a cord set with a J1772 connector/coupler that plugs directly into the vehicle inlet providing approximately 30A or 7.2kW and some first level diagnostics. Some manufactures will not supply a J1772, but will include an adapter enabling use with any certified supply unit.Depending on the battery technology used in the vehicle, Level II charging generally takes 4 to 6 hours to completely charge a fully depleted battery. Today Level II charging is the most widely used medium for electric vehicle charging, Residential, MURB (Multi Residential),Workplace, Public and Fleet are all utilizing 30A charging.


Level III or properly named DCFC (Direct Current Fast Charger) is another form of charging utilizing DC power (direct current) providing much faster charge times. Your electric vehicle must be configured by the manufacture to accept this form of power. DCFC output ranges from 25kw up to a 120kw and the charge times are significantly faster ranging from 15 minutes to 45 minutes. Typically the battery is only charged to approximately 80% of its capacity. The vehicles onboard charger protects the batteries from overheating due to the large inrush of power. The remaining 20% can take up to 6 hrs on a trickle charge to complete.There are two types of connectors utilized for DCFC, Chademo connector and SAE Combo. Other manufactures provide Fast Charging or Super Chargers.

Basic and Network Chargers

Non-Networked or basic chargers (Dumb Charging) have the same amount of power output, but don’t offer the features and benefits of a networked unit. Typically these would be used in an application where the unit is stored in a secure place like a garage or compound and usage data is not required. There are ways to control access by utilizing pedestals, enclosures and analog keypads.

Networked chargers communicate via Cellular, Zigbee, Wifi and Cat 5 to a network that monitors the unit and provides usage data. These units are extremely flexible offering many features such as user authentication, access, power usage, the ability to collect money for station use, fleet management, demand charging, power limiting and building management integration. You can access units by utilizing RFID (radio frequency identification chip) now in credit cards, cards specifically designed by the manufacture for access, RFID stickers or mobile device applications. You also have the ability to control the station through an online account.

Can you re-sell power?

Please click on the link to review: BC Hydro Tariff 9.2. Resale of Electricity
If a Customer wishes to sell Electricity which the Customer has purchased from BC Hydro to a tenant of that Customer on the same Premises on a metered basis, then the Customer shall agree that the selling price for such Electricity shall not exceed the price which BC Hydro would have charged had that tenant been a Customer of BC Hydro. This requirement shall be included in an agreement for resale between BC Hydro and the Customer. In order to sell power by the kWh you must have a weights and measures approved device.

The BC government is currently looking into how they are going to manage re-sellers (station owners) of power in the EVSE segment. Check our Press / Facebook page links for updates.
