1. What Is an EV Charger? Learn About the Two Main Installation Types
An EV charger—also known as an Electric Vehicle Supply Equipment (EVSE)—is a device that delivers power to all types of electric vehicles, including battery electric vehicles (BEVs) and plug-in hybrids (PHEVs).Based on installation type, EV chargers are generally categorized into DC (Direct Current) and AC (Alternating Current) models. Each has its own features and ideal use cases. Let’s take a closer look at the key differences between them.
EV Charger Installation Type 1: DC (Direct Current) Charging
DC chargers , often referred to as fast chargers, offer higher power output—typically allowing EVs to charge up to 80% in just 20 to 30 minutes. Due to their rapid charging capabilities, they’re ideal for time-sensitive use cases.
Since DC charging systems are more complex and costly to install, they’re commonly found at highway rest stops, gas stations, and near freeway exits—making them perfect for commercial EVs. Some parking lots also offer DC chargers for quick top-up charging for everyday drivers.
- Key Features: High power output, shorter charging time, higher installation cost
- Charging Standards: CCS, NACS (formerly TPC), CHAdeMO
- Common Locations: Highway rest stops, gas stations, freeway interchanges, taxi hubs, parking lots (quick charge zones)

EV Charger Installation Type 2: AC (Alternating Current) Charging
AC chargers, often known as slow chargers, deliver lower power output and typically require 6 to 12 hours to fully charge a vehicle. While slower than DC fast chargers, AC chargers are more affordable to install—making them the top choice for residential use.
These chargers are also commonly found in locations where vehicles are parked for extended periods, such as hotels, shopping malls, offices, or residential buildings. This allows EV owners to conveniently charge their vehicles while working, shopping, or resting.
- Key Features: Lower power output, longer charging time, more cost-effective installation
- Charging Standards: Type 1 (J1772), Type 2 (Mennekes), NACS (formerly TPC)
- Common Locations: Homes, offices, shopping centers, hotels, parking facilities

2. What Should You Know Before Installing an EV Charger? 2 Key Factors to Consider
Key Point 1: Choosing the Right EV Charger Installation Type
When installing an EV charger, there are typically two setup options to choose from: wall-mounted or pedestal (standalone) installation. Each type has its own suitability based on space, usage habits, and installation environment.In this section, we’ll walk you through the key differences to help you decide which configuration best fits your charging needs.
(1) Wall-Mounted EV Charger
A wall-mounted EV charger is installed directly onto a wall surface and is typically more compact in size—making it a space-saving solution ideal for residential garages, carports, or underground parking areas. This type of charger is especially popular for home use due to its simple design and efficient use of space.
(2) Pedestal EV Chargers
A pedestal EV charger is a freestanding charging unit that installs directly on the ground without relying on any building structure. This design makes it highly flexible for deployment in a variety of locations.
Due to its larger physical footprint, a pedestal charger is best suited for spacious environments such as outdoor parking lots, or open public areas, where vehicles have enough room to park and charge without obstruction.
For residential settings, where power supply is typically limited to 220V / 75A single-phase and installation space is constrained, a wall-mounted AC charger is generally more suitable. On the other hand, in public or commercial locations with fewer space and power limitations, a high-power DC pedestal charger offers faster charging performance and greater vehicle compatibility.
Step 2: Confirm the Installation Site for Your EV Charger
(1) Installing a Home EV Charger in a Single-Family House
If you live in a single-family home, the installation process is relatively straightforward. Simply have a licensed electrician assess the site for proper wiring and electrical safety. Below are three key considerations:
- Installation Requirement: Installation is allowed once a professional confirms there are no safety concerns.
- Wiring Method: The charger is typically connected from the household electrical panel (behind the main meter).
- Costs: The homeowner covers the installation cost, and electricity usage is billed under the home’s utility account.
(2) Installing an EV Charger in an Apartment or Condo Complex
For those living in condominiums or apartment buildings, additional approvals are required before installation. You must first obtain consent from the building management or homeowner association (HOA). Key points include:
- Installation Requirement: Written approval from the HOA or building committee is necessary before proceeding.
- Wiring Method: A dedicated electric meter and energy management system (EMS) are usually required for proper monitoring and billing.
- Costs: Installation expenses are typically shared by residents, while each user pays individually for their charging usage.

3. Is Installing a Home EV Charger Difficult? Here’s a Quick Guide.
Installing a home EV charger is easier than you might think. With the help of experienced professionals, the process starts with a precise site assessment to determine the best installation location. Combined with a high-quality, stable EV charger and expert setup, you can enjoy safe, reliable, and hassle-free charging at home.
Let’s dive in and walk through the simple steps of a professional home EV charger installation!
Step 1: Pre-Installation Preparation
(1) On-Site Evaluation by a Licensed Technician
Before installing an EV charger, users should schedule an on-site inspection with a certified electrician or installer. This assessment evaluates the safety of the installation site, checks the power connection options, and determines the optimal layout for the charger.
