AC vs DC charging
AC charging (home/destination) runs through the car's onboard charger and is slower — single-digit to ~11 kW — and it's what you'll use most, overnight, at the cheapest off-peak rate. DC fast charging (public) feeds the battery directly at tens to hundreds of kW for road trips. Most charging in real life is slow AC at home; DC is for journeys.
Battery chemistry: LFP vs NMC
LFP (lithium iron phosphate, e.g. BYD's Blade) is durable, fire-safe and happy being charged to 100% daily — ideal for Sri Lanka's heat and everyday use. NMC packs more range per kg but prefers you avoid constant 100% charges. Both are common here; LFP's robustness is a real plus locally.
Regenerative braking
Lifting off or braking turns the motor into a generator, recovering energy to the battery. It extends range (especially on Sri Lanka's hills, where descents claw back charge) and means the friction brakes are barely used — which is why EV brakes last so long.
Connectors
New EVs here mostly use CCS2 for DC fast charging and Type 2 for AC; the older Nissan Leaf uses CHAdeMO for DC. Check your car's port matches the chargers on your routes — the route planner accounts for this.
