Benefits of a Home EV Charger

Making the change from an internal combustion (ICV) vehicle to an electric vehicle (EV) is a huge decision. The two types of vehicles are very different and require a different approach to fueling and maintenance, so expect a learning curve. A big hurdle is to overcome range anxiety. When the ICV fuel light shines, there are plenty of fueling options; at present, a low charge indicator is more serious, with fewer charging options. Therefore, a decision to buy an EV takes planning and forethought to make it a successful choice.

Home EV Charger Options

  1. A Level One charger accompanies the purchase of every EV. This charger is a regular 120v cord that plugs into a normal household outlet. It is a very important charging option since almost every outlet becomes a potential charging station. This alone should alleviate some anxiety. However, a Level One charger is slow; a complete charge, from 0% to 100%, may take 24 hours. Experienced EV owners will avoid letting a charge drop to 0% and charging to 100% since both reduce battery life.
  2. A Level Two charger is a home charger option. This charger uses a 240v cord and is commonly installed in the garage. This requires two dedicated circuits in the electric service panel and professional installation to ensure proper function. Charging time is a matter of a few hours—the range is between 3 and 6 hours, depending on the level of charge.
  3. A Level Three charger is a commercial, quick charge. The Level Three technology is in transition; not every EV can accept high-speed charging and they are not readily available. Charging time for Level Three chargers is a matter of minutes—perhaps as quick as 20 minutes.

Most EV owners seriously consider Level Two chargers, for multiple reasons.

Cost-Effective Home EV Charger

Level One charging is great in an emergency and for folks who drive only a few miles per day. However, the slow charge takes too long for regular use. Level Three charging is also great in some situations but remains uncertain. Level Three chargers are commercial enterprises; the cost of charging at these stations ranges between $10 and $30. Level Two charging varies with the cost of electricity but charging at home costs range between $5 and $10 per charge.

The Convenience of a Home EV Charger

A new EV owner will become keenly aware of every charging station within miles of frequent destinations, and, on occasion, it might be convenient to use commercial chargers. However, nothing will beat the convenience of charging an EV at home overnight.


While using a Level Three charger, an EV must remain stationary for a set number of minutes. While the time is not long, the charging time makes the vehicle vulnerable; the safety of the vehicle depends upon the safety of the charger location. In comparison, a charge from a Level Two station in a residential garage is a much safer option.
