Site capacity assessment
Metered load study against building main switch — sizes the charging network without triggering a transformer upgrade.

Workplace EV charging that scales.
Design, install and operate workplace charging networks — from 4 bays for a small office to 400 for a corporate campus. Load-managed, OCPP-backed, cost-recovery ready.
01 — Overview
Workplace charging works best when it's designed as a shared service, not a per-driver install. ESQ delivers OCPP-managed AC networks that automatically allocate available site capacity, authenticate drivers by RFID or app, and recover cost per session — including FBT-friendly billing paths for staff take-home vehicles.

02 — Capabilities
What ESQ delivers across this practice.
WP-02
Staged deployment
Common cable-tray backbone allows initial bays to be commissioned quickly, with more added as EV uptake grows.
WP-03
Load management
Dynamic per-feeder and site-wide load management shares available capacity across every active charger.
WP-04
Driver auth & billing
RFID / app / plate authentication, with configurable billing — free, flat, $/kWh or $/hr, and FBT-aligned reporting for take-home drivers.
WP-05
Visitor & customer charging
Public-facing AC or DC bays with tap-to-charge, integrated into retail and hospitality billing where required.
WP-06
PV & battery integration
Prioritise excess solar to workplace chargers before export — reduces both energy cost and network demand.
03 — Delivery
A disciplined, engineered process.
- 01
Scope
Site walk, load logging, EV uptake modelling.
- 02
Design
Backbone, charger count, load-management strategy, DNSP paperwork.
- 03
Install
Backbone + first tranche commissioned, OCPP backend configured.
- 04
Operate
Ongoing support, additional bays added on demand.
04 — FAQs
Common technical questions.
- How many chargers do we need?
- Fewer than you'd think — dwell times at workplaces are long, so most staff can share bays on a rotation. We size to actual EV uptake, not headcount.
- Should we charge staff to use it?
- That depends on your FBT and remuneration strategy. We support free, flat, $/kWh, $/hr and reimbursement models — you pick the policy, we configure the backend.
- Can we start small and grow?
- Yes — designing the common backbone for full site capacity up-front lets you commission additional bays cheaply as EV uptake grows. We call this staged energisation.
- Do you handle DNSP approvals?
- Yes. We manage EWR / CCEW / connection notifications across every Australian DNSP.
- Does workplace charging attract subsidies?
- Where charging is bundled with an eligible fleet contract (via Origin 360 EV), the workplace bays can attract up to $4,000 per vehicle subsidy under the ARENA Accelerate EV Fleet program.
