Before delving into the specifics of choosing a home charger, it’s essential to get acquainted with the fundamental concepts of electric vehicle charging. This includes understanding the types of currents, the levels of charging, and the connectors that are integral to the process.
A. Difference between AC (Alternating Current) and DC (Direct Current)
Electricity flows in two ways – Alternating Current (AC) and Direct Current (DC). In AC, the flow of electric charge periodically changes direction, whereas, in DC, it flows consistently in a single direction.
AC Charging: This is the most common type of charging, especially for home-based solutions. AC chargers supply power to the EV’s on-board charger, which then converts the AC into DC to charge the vehicle’s battery. Most residential outlets provide AC power.
DC Charging: Also known as fast or rapid charging, DC chargers send DC power directly to the vehicle’s battery. This is significantly faster than AC charging but usually found in commercial settings due to higher costs and power demands.
B. AC Chargers: Level 1 and Level 2
When it comes to AC charging, there are two primary levels: Level 1 and Level 2.
Level 1 AC Charging: This is the most basic level of charging and usually doesn’t require the installation of additional equipment. You can plug your EV into a standard electrical outlet. However, Level 1 charging is relatively slow and is best suited for overnight charging or vehicles with smaller batteries.
Level 2 AC Charging: Level 2 chargers are faster and require a higher capacity electrical circuit, similar to what you would use for a home appliance like a clothes dryer. These chargers are ideal for all types of EVs and can typically fully charge a vehicle in a few hours.
C. DC Fast Chargers
Unlike AC chargers, DC fast chargers bypass the car’s on-board charger and offer rapid charging, often delivering 100-130 km of range in 20 minutes of charging. There are different levels of DC fast charging with varying power outputs. However, it’s essential to know that not all electric vehicles are compatible with DC fast charging, and repeated use can affect the longevity of the vehicle’s battery.
D. Charging Connector Standards
The type of connector your EV needs depends on the make and model. Here are some common connector types:
- Type 1 (SAE J1772): This is a common standard in North America for Level 1 and Level 2 AC charging.
- Type 2 (IEC 62196): Widely used in Europe and also compatible with many EVs worldwide for AC charging.
- CHAdeMO: This is primarily a DC charging standard popular in Japan and also used by some EV manufacturers globally.
- CCS (Combined Charging System): This connector allows for both AC and DC charging and is becoming a global standard for electric vehicles.
Understanding these basic concepts will provide a solid foundation for making informed decisions regarding the type of home charger that best suits your electric vehicle and lifestyle needs.
