Mexico Taxi-Depot DC Fast Charging Case Study

Nancome one-stop delivery for high-throughput fleet charging

Mexico is accelerating EV adoption in major cities through rapid fleet electrification (taxis, ride-hailing, delivery), supported by public-private corridor projects; Federal and state policies promote local manufacturing, streamline imports, and create low-emission zones, while utilities introduce time-of-use tariffs and demand-charge mechanisms for depot charging. Consequently, high-throughput, floor-standing GB/T dual-gun DC chargers linked to an OCPP backend are emerging as the preferred solution to match fleet shift schedules and deliver audit-ready energy and cost control.

1) Project Overview

· Customer: A Mexico City taxi company operating 24/7 shifts.
· Scenario: Night-time depot charging with daytime quick turnarounds.
· Configuration: Nancome dc ev charging station cabinets in floor-standing form factor only (no wall-mounted units). Each cabinet is a GB/T dual gun DC charger with dynamic power sharing; layout supports staged expansion.
· Delivery: Under a single contract Nancome handled feasibility,ev fast charging station installation, software onboarding, and O&M playbooks.

2) Site Context & Challenges

· Peaky demand: Shift changes drove charging waves around 7–9 p.m. and 5–7 a.m.
· Depot constraints: Limited maneuvering space and mandated fire-egress routes.
· Ops discipline: Need for self-service, visible queues, and minimal staff intervention.

3) Solution Design

Power Layout
· Zebra layout with fast-turn floor-standing bays nearest the gate; clear one-way circulation and bollards protect walkways.
· GB/T dual gun power sharing lets dispatch choose a single high-power push or balanced split for two taxis depending on SOC.
·Canopy lighting improves night safety; maintenance aisle behind cabinets speeds service.

System Software
· A unified car electric charging station system links chargers, meters, tariffs, and access control.
· Fleet accounts via the commercial ev charger with app: drivers view bay status, start/stop sessions, get SOC/ETA and receipts; dispatch monitors queues and assigns priority.
· Load management caps site kW at the service entrance and auto-schedules charging to valley tariffs.

Build Compliance
· As experienced dc fast charger manufacturers, Nancome supplied climate-ready enclosures with harmonized grounding, surge, and ventilation.
· Turnkey ev fast charging station installation covered civil works, cabling, commissioning, and driver training.

4) Implementation Highlights (night-shift photo) 

· Covered floor-standing DC bays keep approach paths clear and cables protected.
· Fast lanes near the exit enable 15–35-minute top-ups that return taxis to service quickly.
· App-based self-service reduced queue disputes and improved on-time departures.

5) Outcomes & ROI Snapshot*

*Indicative from comparable Nancome fleet depots; actuals vary by tariff and duty cycle.
· Throughput: +28–42% vehicles charged per night after dynamic sharing on GB/T dual gun DC chargers.
· Driver time saved: Peak-hour wait reduced by ~30–40%.
· Energy cost: Valley-tariff scheduling trimmed site kWh cost by ~12–18%.
· Revenue control: Accurate per-vehicle billing via the app with role-based access.
· Uptime:  >99% thanks to remote diagnostics and hot-swap modules.

6) Scalable Roadmap

· Anchor fast-turn lanes: Keep high-power floor-standing bays for dispatch-critical taxis.
· Capacity growth: Add more GB/T dual gun DC chargers along the back row as fleet size expands.
· Energy strategy: Optional PV carport + storage to shave demand charges and improve resilience.

7) Why Nancome

· Solution over hardware: We deliver a fully run car electric charging station system, not just cabinets.
· One-stop execution: From study to build to software to training, one accountable partner.
· Data-driven ops: App analytics guide pricing, bay mix, and future expansion.
· Serviceable design: Modular power, remote updates, and localizable interfaces keep fleets rolling.

Result: With Nancome’s integrated approach—combining robust floor-standing dc ev charging station cabinets, a driver-friendly commercial ev charger with app, and disciplined ev fast charging station installation—the Mexico taxi depot converted nightly peaks into predictable, efficient operations on GB/T dual gun infrastructure.
