A Basic Guide to Purchasing and Installing a Home Electric Vehicle Charger

December 6, 2013

Electric vehicle newbies may be surprised to find out that the vehicle’s electric charger is located on board. This equipment is deeply seated in the inner part of the car to convert an AC source to a DC. This makes it is possible to charge your vehicle’s battery pack. Nearly everybody knows that a charger is a wall-mounted box supplying 240 volts of electricity. Actually, a technical name for the box in question combined with a plug and code is EVSE or Electric Vehicle Service Equipment. An electric vehicle owner would need to install one of these at their home. We will shed light on purchasing an EVSE, which basically refers to an electrical device that allows drivers to connect their cars to an electricity source. There are a number of significant variations between different types of home chargers. Additionally, a few practices should be kept in mind.

Amperage Capacity

It is advisable to purchase a charger to handle more than 30 amps. According to averages, a 30-amp service gives a driver the potential to get approximately an additional 30 miles range per hour. Similarly, 15 amps would give an additional 15 miles in charging hour. It is important to note that EVSE with 30 amps requires at least a 40 amps circuit breaker.


Most experienced electric vehicle drivers hold a general consensus that EVSE that is durable and with a high capacity costs approximately 1000 dollars. This cost could be quite less or double, excluding the installation costs. There are a number of features including connectivity and portability that could cause an increase in price. To reduce the cost, it is advisable to avoid such features. Most electric vehicle drivers could get free EVSE from the year 2010 through the year 2013.


If possible, it is advisable not to install an EVSE permanently. This implies that you need to have an electrician to install NEMA 14-50 outlet. A plug should then be put on a pigtail that is mounted to the EVSE. In case you decide to relocate at some point, you need to simply unplug the charger and then plug it to a different NEMA outlet. The approach mentioned is similar to a hard-wire installation in terms of costs.


With advanced technology, there are numerous smart grids and smart phones, which may compel electric vehicle owners to purchase EVSE that is Wi-Fi enabled. However, this move might not be a smart one. Connectivity would only add pointless complexity.
