How does OnCharge work for EV owners?

OnCharge supports charging EV’s in three different ways.

Using an OnCharge meter plug

The plug measures the consumption and uploads to our Cloud service over Wifi. Perfect for employees charging their cars at home with their original plug-in charger.

Using a Gen 3 Tesla Wall Charger

OnCharge have designed an solution to work with this low cost and popular 7.2kw Generation 3 Tesla wall charger. The Type 2 connector on the Tesla charger works with most NZ new electric vehicles.

Using a DIN Rail power meter

The Wifi power meter is connected to an electrical circuit like an outdoor power point, a third-party EV charger or even a whole premises or tenancy – perfect for a Hotel, Motel or AirBNB to measure and control power usage, and instantly bill a customer.

OnCharge can measure & bill almost any kind of energy usage.

Whether it’s a single usage transaction like charging an Electric Vehicle, or an accumulation of transactions like charging a car multiple times over a month, OnCharge can rate the usage of electrical consumption and charge in one of several ways.

1. A singular transaction like a public EV charge

Rate the consumption of power between the start and end of the charging transaction, and instantly bill a credit card or Apple Pay wallet.

2. Accumulate transactions & bill them at the end of a period

Total up the transaction usage and create an Invoice in an accounting system like Xero / QuickBooks or create a record in a payroll system for employee reimbursement. This could be used for example for reimbursing an employee or contractor, or for charging energy usage to a subtenant over a monthly period.
