Electric vehicle charging stations
Electric vehicle charging stations allow consumers to charge their electric car by buying electricity. Various levels of government and private industry organizations have started to install these stations to invest in clean technologies.
Many of these charging stations use measurement systems that involve new technologies. These new technologies must comply with different federal measurement laws depending on how the electricity is sold.
Electricity sold on the basis of time
Charging stations that are only intended to sell prepaid energy on the basis of time must:
- charge the customer for time within the limits of error set in the Weight and Measures Act
- state the price per unit of time
Electricity sold on the basis of energy
Charging stations that sell electricity on the basis of energy (kWh) or time-related demand (kW) are considered meters. This means that device owners must:
- use defined units of measurement
- make sure the meter type is approved by Measurement Canada
- find an authorized service provider to inspect a new meter before using it and to reinspect the meter periodically
- make sure the meter is sealed properly
- register as a contractor to sell electricity
