This document describes Tevi's EV charging tool, which aims to simplify decision making for businesses on electric vehicle charging infrastructure. The tool guides businesses through assessing their needs and site considerations to identify the appropriate charger type and installation requirements. It also provides information on funding support available and connects businesses to potential installation partners. The overall goal is to help expand the local EV charging network and support the transition to more sustainable transportation.

Charge profile – 0 – 80% ‘full charge’
Note: This profile assumes that an EV arrives with an entirely depleted battery, and the driver expects to fully charge. This rarely
occurs in the case of destination charging, with the majority of charging done at home. This is more prevalent at service stations, to
allow short stops during long journeys.
