Some homes might have insufficient electric capacity for Level 2 equipment. Purchasing safety-certified equipment is recommended, such as the products certified under the ENERGY STAR label, which are tested by a nationally recognized testing laboratory, along with having a certified electrical contractor.Įlectricians can inform homeowners whether their home has adequate electrical capacity for vehicle charging. More advanced, 'smart' Level 2 products have features such as data collection, user interface systems, enhanced displays, charging timers, communications capabilities, and keypads. Most Level 2 products have standard safety features and status lights. State and utility incentives may be available to help offset the cost of charging equipment.
Level 2 charging equipment can be installed for drivers with less regular schedules, longer commutes, or EVs with large batteries that require more than overnight (or the typical dwell time) to fully charge. Many EV owners are able to meet their daily driving range requirements by charging overnight with Level 1 equipment, requiring no additional cost or installation, provided that a power outlet on a dedicated branch circuit is available near their parking location. EV owners may install Level 2 (240 V) charging equipment in their homes for a faster charge, or opt for the Level 1 cordset provided with the vehicle as shown here.
