EV charging explained: AC vs DC, and what you need at home

Charging sounds complicated until you learn one distinction: AC vs DC. Get that, and the rest — plugs, speeds, home setup — falls into place.

New EV owners in the Philippines usually have the same first question: how, exactly, do I charge this thing? The good news is that day-to-day charging is simpler than refuelling — you mostly do it at home while you sleep. Here's what actually matters.

AC vs DC: the only concept you need

Your home outlet supplies alternating current (AC). An EV battery stores direct current (DC). Every EV has an onboard charger that converts AC to DC — but it converts slowly, which is why home charging takes hours. Public fast chargers skip that bottleneck by supplying DC straight to the battery, which is why they're far quicker.

The three ways you'll charge

• Level 1 — a normal wall socket (AC). Plug into a standard outlet with the cable that comes with the car. It's slow (adding maybe 10–15 km of range per hour) but needs no installation. Fine for a light daily commute topped up overnight.
• Level 2 — a home wallbox (AC). A dedicated 7–22 kW charger installed by an electrician. This is the sweet spot for most owners: a full charge overnight, every night. Expect a one-time cost for the unit plus installation.
• DC fast charging — public stations. Found at malls, fuel stations and highway stops, these add a large chunk of range in 20–40 minutes. They cost more per kWh than home charging, so treat them as top-ups for long trips, not your daily source.

What to install at home

If you own your parking spot and drive daily, a Level 2 wallbox pays for itself in convenience. Have a licensed electrician check your home's electrical capacity first — a wallbox draws real power, and older wiring may need an upgrade or a dedicated breaker. If you rent or park on the street, a portable Level 1 charger plus occasional public DC charging can still work; just be honest about whether you can reliably plug in.

Plug standards in the Philippines

Most new EVs sold here use Type 2 connectors for AC charging and CCS2 for DC fast charging, which has become the common standard. Some models — particularly certain Japanese ones — use CHAdeMO for DC. Public networks are expanding but still concentrated in Metro Manila, Cebu and along major expressways, so plan longer provincial trips around known stops.

The cost angle

Home charging at your utility's residential rate is where nearly all the savings live. Public DC charging is priced higher per kWh for the speed and convenience — still usually cheaper per kilometre than petrol, but not the bargain that overnight home charging is. If you can charge at home, you capture the full benefit; the calculator's figures assume exactly that.
