What is Level 1, 2, and 3 charging?
Understanding Level 1, Level 2, and Level 3 EV Charging in the Philippines
As electric vehicles (EVs continue to grow in popularity, understanding the different levels of EV charging can help you choose the solution that best fits your lifestyle. EV chargers are generally categorized into three levels: Level 1, Level 2, and Level 3 (DC fast charging)—each offering different charging speeds, installation requirements, and use cases.
Level 1 Charging
In the Philippines, Level 1 charging uses a standard household outlet and delivers electricity at a relatively low power level. While widely accessible, Level 1 charging is very slow and is best suited for daily use or emergency charging, as it can take a long time to fully recharge an EV with a larger battery.
Level 2 Charging
Level 2 chargers are also AC (alternating current) but require a dedicated circuit and professional installation, typically through a wall-mounted charger in a garage or driveway. This setup delivers significantly more power than Level 1, allowing most EVs to be charged within several hours, making it ideal for home, workplace, and destination charging.
For homeowners looking for a safe and hassle-free setup, Greenstrum provides professional Level 2 home charging installations tailored to household electrical capacity.
Level 3 Charging (DC Fast Charging)
Level 3 charging—also known as DC fast charging—uses direct current (DC) and bypasses the vehicle’s onboard charger to deliver power directly to the battery. These chargers are designed for public and high-traffic locations, providing rapid charging for long trips or quick top-ups.
Here is a quick breakdown of Level 1, Level 2, and Level 3 charging.
Level 1 (Home Charging) | Level 2 (Home and Commercial AC Charging) | Level 3 | |
|---|---|---|---|
Power | Plugs into a standard 220–230-volt household outlet, commonly available in Philippine homes. Power output ranges from 1.3 kW to 2.3 kW. | Requires a dedicated electrical connection with a higher power output than a standard household outlet. Level 2 AC chargers are available in different power ratings: 7.0 kW – most common for residential use, while 11 kW to 22 kW – mostly used in commercial or industrial settings. | Level 3 chargers—also known as DC fast chargers—bypass the vehicle’s onboard charger and deliver direct current (DC) straight to the battery. DC chargers range from 30 kW to 480 kW power output. |
Installation | No special installation is required, making it the simplest and most accessible option. Most EVs come with a portable Level 1 charging cable that can be plugged directly into a wall outlet. | Involves installing a wall-mounted AC charger at home or in commercial locations, similar to installing a split-type air-conditioning unit. Professional installation is required to ensure safety and proper electrical capacity. | These high-powered chargers are installed in public locations such as select ACMobility Charging Hubs nationwide. |
Charging speed | This is the slowest charging option. Charging a 60 kWh battery from low to full can take 40 hours or more, depending on the vehicle and conditions. | Significantly faster than Level 1. A typical 7 kW Level 2 charger can charge a 60 kWh battery in about 6 to 10 hours, making overnight charging practical. | These high-powered chargers are installed in public locations such as select ACMobility Charging Hubs nationwide. |
Use case | Best suited for light daily driving, overnight top-ups, or emergency charging when faster options are unavailable. | Ideal for home charging, workplaces, condominiums, malls, and offices—especially when a full charge is needed within the same day. |
Key Considerations for EV Charging in the Philippines
Voltage: While the standard household voltage in the Philippines is 220V, you'll need a dedicated circuit for Level 2 charging, which typically involves getting a new circuit breaker installed.
Connector Standards: AC charging uses Type 2 and GBT connectors. DC charging uses CCS2 (Combined Charging System). It is a DC fast charging connector that combines a J1772 plug with additional DC pins. This is the Department of Energy standard that is used with most EVs sold in the Philippines today.
Level 1 charging is a practical solution for those who don't need fast charging and prefer a minimal investment.
Level 2 is ideal for home installation and serves as the primary charging option for most EV owners.
While not suitable for home use due to cost and power requirements, Level 3 charging is essential for expanding the practicality of EVs for all driving scenarios.
Each EV charging level has its place. Level 1 is budget-friendly and simple, Level 2 balances speed and accessibility, and Level 3 delivers rapid charging when time is critical. Understanding these options helps EV owners make smart decisions based on their lifestyle and driving needs.
