Why Investing in Level 2 Electric Vehicle Charging Stations Is Worth It

Level 2 chargers are primarily designed for regular charging rather than rapid charging. They provide more power than Level 1 while generally requiring less charging infrastructure than DC fast charging.

How Does Level 2 Charging Work?

Level 2 charging supplies alternating current, or AC, to the electric vehicle. The vehicle's onboard charger converts that energy to DC before it reaches the battery. This is different from DC fast charging, where the charging equipment supplies direct current directly to the vehicle's battery system.

The actual charge rate depends on several factors:

• Power output: Determines how much energy the charger can deliver.

• Vehicle capability: The EV can only accept as much power as its charging system allows.

• Battery pack: Battery capacity affects the total energy needed.

• Battery level: Charging behavior can change as the battery becomes fuller.

• Efficiency: A more efficient vehicle can gain more driving range from the same amount of energy.

• Charger type: Different EV chargers have different power ratings and connector configurations.

This means a higher-rated charger does not automatically make every vehicle charge faster. The charger and vehicle need to be capable of operating at the same charge rate.

How Fast Is Level 2 Charging?

Charging speeds for Level 2 equipment in the U.S. can range from about 3 to 19.2 kW. AC Level 2 chargers typically max out at 19.2 kW and 80A, while many residential installations operate at lower power levels. As a general reference, Level 2 chargers can add roughly 10 to 60 or more miles of range per hour depending on the charger's power, vehicle efficiency, and other charging conditions.

What affects Level 2 charge time?

• Vehicle's battery size: A larger battery pack generally requires more energy to fully charge than a smaller battery.

• Power output: A 9.6 kW charger can deliver more energy per hour than a 3.8 kW charger when both are operating within the vehicle's limits.

• Charge rate: The vehicle determines how much AC power it can actually accept.

• Battery level: The charging rate can change as the battery approaches a high state of charge.

• Vehicle efficiency: An efficient EV may gain more range per hour of charging than a less efficient vehicle using the same power.

For this reason, published range-per-hour figures should be treated as estimates rather than guarantees.

Level 1 vs. Level 2 Charging

Level 1 uses a standard 120V household outlet and can be suitable for EV owners with shorter daily driving needs. Level 2 uses higher voltage and provides substantially more charging power. Level 1 can provide about 2 to 5 miles of range per hour, while Level 2 can provide about 10 to 20 miles per hour, depending on the equipment and vehicle.

Level 2 can be particularly useful when an EV needs to recover a larger amount of range overnight.

Level 2 vs. DC Fast Charging

Level 2 and DC fast charging serve different purposes. Level 2 uses alternating current, while DC fast charging uses direct current (DC). With AC charging, the vehicle's onboard charger handles the AC-to-DC conversion. DC fast charging performs that conversion outside the vehicle, allowing the charging station to deliver much higher power.

DC fast chargers make sense when an EV driver needs to add substantial range during a short stop. Level 2 is better suited to situations where the vehicle can remain plugged in for several hours.

Can Level 2 charging be better for battery health?

Charging behavior can affect EV battery degradation, although battery health also depends on temperature, state of charge, vehicle design, and other factors. Research found that vehicles relying heavily on high-power DC fast charging above 100 kW experienced faster average degradation than vehicles primarily using AC or lower-power charging.

That does not mean Level 2 charging guarantees better battery health. It does mean that using lower-power AC charging for routine charging can reduce reliance on high-power DC fast charging when rapid charging is not necessary.

How Much Does a Level 2 EV Charger Cost?

The cost of a Level 2 charging setup includes more than the charger itself.

What goes into the total cost?

• EV charger: The equipment purchase price.

• Electrical circuit: A dedicated circuit is generally required.

• Installation: Labor and materials add to the cost.

• Permits: Local requirements can apply.

• Electrical upgrades: An existing panel may need additional capacity.

• Additional equipment: The installation may require other electrical components.

Current consumer estimates place Level 2 installation in the several-hundred to several-thousand-dollar range, depending heavily on the property and electrical work required. Estimates range from $400 to $900 for installing a 240V outlet, including labor, materials, permits, and inspections, with the charger itself treated as an additional cost.

Some market estimates put complete Level 2 installation at around $749 to $2,500, with an average near $1,700. These figures should be treated as general estimates rather than a universal installation price.

Can rebates reduce the cost?

Potentially. Local utility rebates, state incentives, and other programs may help offset the cost of installing Level 2 charging equipment. Availability and eligibility vary by location, so EV owners should check current local and utility programs before including an incentive in their cost calculation.

Can Level 2 Charging Save You Money?

Home charging can cost less than some public charging options, but the difference depends on electricity rates, public charging prices, vehicle efficiency, and how often you charge. For example, a residential electricity rate could be15.45 cents per kWh, while public charging rates could be approximately $0.30 to $0.55 per kWh depending on location, charging speed, level, and time of day.

For drivers who frequently use public charging stations, charging more often at home can potentially reduce the amount spent on public charging. However, the initial charger and installation cost must be included when calculating the overall value.

Why Level 2 Is Ideal for Everyday Charging

Level 2 charging is well suited to EV drivers who leave their vehicle parked for several hours at a time. Homes and workplaces are particularly practical locations because an EV can charge while the driver is sleeping, working, or handling other activities.

Everyday benefits

• Charge overnight: A Level 2 charger can replenish a significant amount of energy while the vehicle is parked overnight.

• Support daily commuting: Regular home charging can replace much of the energy used during the day's driving.

• Reduce public charging stops: A reliable home charger can reduce dependence on public charging stations for routine charging.

• Reduce range anxiety: Knowing that the vehicle can charge overnight can make it easier to maintain the range needed for the next day.

Is a Level 2 Charger Compatible With Your EV?

Level 2 charging is compatible with virtually all modern battery electric vehicles and plug-in hybrid vehicles, but the specific connector and power capability still need to be checked.

Check the connector type

Common Level 2 connectors in North America include SAE J1772 and NACS. DOE identifies J1772 and J3400/NACS as Level 2 connector options in the U.S.

• J1772: The traditional standard for AC Level 1 and Level 2 charging in North America.

• NACS: Tesla's charging standard, now recognized as SAE J3400 for EV charging in North America.

• Type 2: Commonly used for AC charging in Europe.

CHAdeMO and the Combined Charging System, or CCS, are primarily associated with DC fast charging rather than ordinary Level 2 charging. GB/T is widely used for charging standards in China.

The connector is only part of compatibility. You should also check your vehicle's maximum AC charge rate and the charger's plug type.

What Should You Look for in a Level 2 Charger?

The right charger should match the EV, electrical system, parking setup, and expected charging speed.

Consider these factors:

• Power output: Match the charger to the vehicle's maximum AC charging capability.

• Connector: Choose J1772 or NACS based on the vehicle.

• Plug type: For plug-in chargers, make sure the electrical connection matches the outlet.

• Cable length: Consider the distance between the charger and the vehicle.

• Charge rate: Higher output is useful only when the vehicle can accept it.

• Installation: Determine whether a plug-in or hardwired setup makes sense.

• Safety: Check for appropriate certifications and protection features.

• Smart features: Wi-Fi and smartphone app integration can add convenience.

• Warranty: Include warranty coverage in the overall purchase decision.

The most powerful charger is not necessarily the best fit. A compatible charger with the right power output can provide a more practical charging experience.
