The chargers you will see
Three kinds of charger are on ChargeLK. Pictures are simple drawings, not any one brand.
On a wall at homes, hotels and shops. A slower charge, good for hours of parking.
Free-standing in car parks and by the road, often with two plugs.
On highways and at fuel stops. About 20 to 60 minutes for most of a charge.
For charger owners: what your charger needs
Any charger that speaks OCPP 1.6J (OCPP 1.6 over JSON) can join. Chargers that speak only OCPP 2.0.1 cannot connect yet.

wss://chargelk.com/ocpp/followed by your charger's ID, for examplewss://chargelk.com/ocpp/CP-001- Charger ID

After a charger connects we ask it to send meter readings often (MeterValueSampleInterval), so drivers see live energy and we can stop a charge before a wallet runs out. Drivers start from the app (QR or the charger's ID), or tap a card that is registered with ChargeLK.
