Assessing Your Charging Requirements
Defining your charging needs is the first step. Depending on factors like:
- Daily driving and mileage
- Access to home, workplace or public charging
- Time availability for charging sessions
You‘ll need to determine:
- Charging level (Level 1, Level 2 or DC fast charging)
- Charging locations (home, en route, destination)
- Charging speed requirements (slow overnight or fast daytime)
This chart summarizes the key differences between charging levels:
| Charging Level | Speed | Miles of Range/Hour | Best For |
|---|---|---|---|
| Level 1 | Slow | 2-5 miles | Overnight charging |
| Level 2 | Faster | 10-20 miles | Home & public charging |
| DC Fast Charge | Fastest | 60-80 miles (in 15-30 min) | En route quick charges |
Tip: Installing a Level 2 or DC fast home charger substantially reduces public charging needs.
Charging Levels and Speeds
Let‘s explore more details on EV charging speeds and power levels:
Level 1 AC Charging
- Uses 120V household outlet
- Typically provides 2-5 miles of range per hour charged
- Best for slower overnight top-ups
- Needs ~20 hours for full charge (varies by EV battery size)
- Requires portable EVSE cable (included with most EVs)
Pros: No added electrical work needed | Cons: Very slow charging times
Level 2 AC Charging
- Uses 240V electrical circuit (like for dryer outlet)
- Provides 10-20+ miles of range per charging hour
- Enables full charge overnight for most EVs
- Requires hardwired wallbox or pedestal mounted station
Pros: Faster charging for daily commute | Cons: Installation costs
DC Fast Charging
- Direct current (DC) charging protocol
- Offers 60-80 miles of range in 15-30 minutes
- Requires 480V or higher power supply
- Supported by CCS, CHAdeMO, Tesla Supercharger, etc.
Pros: Ultra-fast charging for road trips | Cons: Very high electrical supply requirements
As you can see, Level 2 AC is the "Goldilocks Zone" for home and public charging for most drivers. While DC fast charging provides quick bursts for long trips. Choose what best fits your lifestyle!
Connector Types and Standards
There are a few main charging connector types and standards including:
J1772
The North American standard for Level 1 and Level 2 AC charging. Used by most non-Tesla makes.
CCS (Combo)
Combines the J1772 AC pins with two extra DC pins for fast charging. Used by many US and European automakers.
CHAdeMO
The DC fast charging standard used by Nissan, Mitsubishi and other Asian automakers.
Tesla
Tesla uses its own proprietary connector for Level 1, 2 and DC fast charging. Adaptors allow Teslas to use J1772 public chargers.
So select chargers supporting the plug that matches your EV!
Public Charging Infrastructure Growth
The public charging network has expanded enormously in recent years. There are now over 100,000 public charging ports in the US, as this chart shows:
| Year | 2015 | 2018 | 2021 | 2025 (projected) |
|---|---|---|---|---|
| Public EV Charging Ports | 16,000 | 44,000 | 100,000+ | 1 Million+ |
In particular, DC fast charging (DCFC) stations are growing rapidly, with over 8,000 DCFC ports now available. This enables convenient fast-charging pitstops for long trips in EVs.
Many new public EV chargers also feature advanced capabilities like smart load balancing, dynamic power sharing, integrated cable management, open charge point protocol (OCPP) compliance for easy network integration, and flexible payment options via apps and RFID.
Charging Station Power Levels
EV charger output power determines charging speed capability. As vehicles accept faster charge rates, high-powered options are increasingly in demand.
| Charger Power Rating | Typical Charge Speed Added |
|---|---|
| 3.3 kW – 7 kW | 10-20 miles per hour |
| 10 kW – 25 kW | 25-35 miles per hour |
| 50 kW | 180 miles in 20 minutes |
| 150-350 kW | 200+ miles in 15-30 minutes |
Higher power also allows serving multiple vehicles simultaneously, by dynamically splitting power between ports using smart load balancing.
So future-proof by selecting chargers capable of the fastest charging rate your EV can handle.
Installation and Electrical Considerations
Appropriate electrical capacity is critical for installing EV charging equipment. Key factors:
Home Charging
For AC Level 1 and Level 2 home charging, consider:
- Available electrical panel amperage rating
- Presence of suitable 240V outlet or circuit for Level 2
- Electrical upgrade costs if added capacity needed
Typical guidelines per charging level:
| Charging Solutions | Electrical Panel Capacity | Voltage/Amps |
|---|---|---|
| Level 1 | 100 amp or higher | 120V/15A |
| Level 2 | 150 amp or higher | 208/240V/30A-50A |
Public/Commercial Charging
DC fast charging requires very high capacity:
- Commercial 208/480V 3-phase electrical service
- 150 to 800 amps minimum
- May also need utility service upgrades
Site load studies help determine appropriate infrastructure to be installed cost-effectively while delivering desired charge rates.
Charging Station Types
Charging stations come in a variety of physical forms and mounts to suit specific locations:
Residential Wall Mount
- Indoor/outdoor use
- Small footprint
- Roomy 16 ft. charging cables
Ideal for garages, carports
Commercial Pedestal Mount
