How many units (kWh) does a ev home charger use per month?

Running 4 hours a day at 7,000 W, a ev home charger consumes about 840 units per month — that's 28.0 units per day.

How much does it cost per month on the 200-unit slab?

On the Unprotected 101–200 unit slab (Rs. 22.95/unit) the energy charge alone is about Rs. 19278. Add ~Rs. 2520 for FPA + QTA and 18% GST on top.

Is a ev home charger cheaper to run on protected tariff?

Yes — at Rs. 11.69/unit (protected slab 1–100 units) the same 840 units cost only Rs. 9820, roughly half. But qualifying requires staying under 200 units total for 6 months, which is hard when this appliance alone uses 840 units.

Does running it during off-peak hours save money?

Only if you have a Time-of-Use (TOU) meter — typically 3-phase domestic, commercial A-2 or industrial B-2. On a flat single-phase domestic meter the tariff is the same 24 hours. See your DISCO's peak-hours page for exact windows.

Will solar make this appliance free to run?

Solar cuts the daytime portion of this load to nearly zero. Under the 2026 net-billing regime, exported units are worth Rs. 11–13 vs Rs. 27–42 for units you self-consume — so timing the appliance to run in daylight matters far more than it did on old net-metering.

EV home charging cost in Pakistan (2026)

A 7-kW single-phase AC EV charger delivers ~40 km of range per hour. Charging 4 hours a night to cover a 100-km daily commute adds Rs. 15,000–35,000 to your monthly bill on the unprotected slab — but only Rs. 8,000–10,000 if you shift it to off-peak on a TOU meter.

Cost per slab — NEPRA Unprotected Residential (FY 2025–26)

Energy charge only. Add ~Rs. 2520/month for FPA + QTA at typical rates, then 18% GST on the total. Electricity duty and PTV fee are also stacked — see the full electricity bill calculator for the complete tax pass-through.

Protected consumers (≤200 units, 6-month rule)

Slab	Rs./unit	Per month cost
1–100 units	11.69	Rs. 9820
101–200 units	14.16	Rs. 11894

Check your Protected consumer eligibility — the ≤200 unit rule is strict and one bad month resets the 6-month counter.

Cut the running cost

Get a TOU meter — off-peak rates cut EV charging cost by ~35%.
Time the charger to finish just before you leave; batteries last longer at 80% SoC than 100%.
A 3.3-kW slower charger uses the same kWh but shifts more of the session into off-peak hours.
Solar + net-billing (2026 regime) pairs poorly with EVs — export rate is now Rs. 11–13 vs Rs. 42+ import; self-consume during the day instead.

Fine print

22 kW 3-phase chargers exist but require a commercial B-2 tariff meter and are rarely worth it for a home installation.
