1. Introduction

Commercial EV charging is a scale business built from many small sites. A restaurant chain adds chargers at 40 locations; a hotel group equips 25 properties; a parking operator upgrades 15 garages; a retail franchise rolls out charging at 60 stores. In each case, the decision-maker needs a charger that is affordable enough to deploy in volume, robust enough to survive unattended outdoor duty, and smart enough to generate revenue beyond the kWh margin. The MIDA 60kW/120kW DC Electric Car Charger with Interactive Advertising Display answers all three requirements, packaged in an IP55-rated enclosure that is the practical benchmark for commercial outdoor installation.

The 60kW and 120kW power levels bracket the two most common commercial scenarios. The 60kW configuration serves destination sites — hotels, restaurants, gyms, offices — where vehicles dwell for 45 minutes to several hours and where grid capacity is often limited. The 120kW configuration serves higher-turnover sites — retail parks, parking garages, convenience centers — where drivers expect a substantial charge in 20–40 minutes. Both share the same cabinet, display, and management platform, which means a multi-site operator can standardize on one product, one spare-parts pool, and one training program.

Positioning summary: this is the volume-deployment product of the MIDA family — the charger that makes the dual-revenue model practical at portfolio scale. The interactive advertising display engages drivers during the session, generates sponsorship income, and doubles as a customer-communication channel for the site owner. The IP55 rating is the engineering promise: dust-proof and water-jet resistant, the unit is designed to sit outdoors, exposed to weather, for years with minimal maintenance. The sections below examine the interactive display, charging performance, safety and durability, management platform, specification, and deployment playbook for commercial portfolios.

2. Interactive Advertising Display: Engagement and Revenue at Portfolio Scale

The interactive display on the 60/120kW charger — 32-inch or 43-inch touchscreen, configurable — is the engagement engine of the product. Unlike passive screens, the touch interface allows drivers to interact with content: redeem coupons, scan QR codes, answer surveys, access local information, and control non-critical settings. For advertisers, interactive inventory commands 1.5–3× the CPM of passive DOOH because engagement is measurable and verifiable; for site owners, the screen is a direct channel to the customer standing at their property.

The hardware is built for unattended commercial duty: 1920×1080 resolution, 1500–2000 nits brightness with ambient-light adaptation, projected-capacitive touch that works with gloved hands and rejects water droplets, IK10-rated tempered glass, and an IP65 display housing. The panel operates from -25°C to +55°C with heat-pipe cooling and auto-dimming, and is rated for 50,000 hours of continuous operation.

The commercial model at portfolio scale is straightforward and compounding:

• Site-level sponsorship: each screen attracts 1–3 local advertisers at €100–€600 per month per advertiser, producing €100–€1,800 per site per month of media income.
• Network packaging: an operator with 25 sites can package screens into a regional network, selling inventory at rates unavailable to single-site owners.
• Internal promotion: the site owner reserves slots for its own offers — restaurant specials, hotel packages, garage membership deals — lifting the core business directly.
• Engagement data: touch and redemption analytics give advertisers proof of performance and give the operator a proprietary data asset for rate negotiation.

The CMS supports multi-tenant scheduling, day-parting, geo-targeting, campaign design, QR generation, redemption tracking, and split-screen charging status. The interactive layer can be locked into an information-only mode when no campaign is active, keeping the screen useful for wayfinding and site messaging at all times.

For the multi-site operator, the screen transforms a cost-center rollout into a revenue-generating portfolio. Even at conservative fill rates, media income typically covers 15–30% of the sites’ total operating cost — electricity included — from the first year, while the internal-promotion value lifts the core business invisibly.

3. High-Performance Charging Technology: 60kW/120kW Configurations

The power stage is a proven, modular DC platform configured at 60kW or 120kW. The 120kW configuration supports dual-gun operation with dynamic power sharing (60kW+60kW or 120kW to one vehicle); the 60kW configuration is single-gun, with an optional second gun for dual-bay flexibility. This gives portfolio operators a single cabinet platform that adapts to each site’s traffic pattern.

The 150–1000V DC output range is retained across both configurations, ensuring compatibility with 400V and 800V vehicle architectures — a critical detail as the vehicle parc transitions. Per-gun current reaches 150A (60kW) or 250A (120kW), and peak efficiency of 95%+ keeps energy losses low. Input is 400V AC three-phase, 50/60Hz, ±15%; the 60kW configuration frequently installs on existing commercial supplies with minimal reinforcement, which is often the deciding factor for retrofitting older buildings.

Connector options are configured at order: CCS2, CCS1, hybrid, GBT, and NACS adapter readiness. OCPP 1.6J (2.0.1 optional), DIN 70121, and ISO 15118 Plug & Charge are supported. Smart-charging features — time-of-use tariffs, load management, scheduled windows, demand response — let the operator control energy cost across the portfolio. The charging process includes pre-session safety checks, insulation monitoring, emergency stop, and graceful derating in extreme temperatures, with reliable cold-weather startup.

4. Safety and Reliability: The IP55 Promise

IP55 is more than a specification line; it is the engineering contract for outdoor commercial installation. The rating certifies protection against dust ingress (level 5) and against water jets from any direction (level 5) — the practical requirement for a charger mounted in an open car park, exposed to rain, snow, and hose-down cleaning. The MIDA enclosure delivers this with fully gasketed seams, sealed cable entries, and corrosion-treated steel, while the display housing goes further at IP65.

The safety architecture is comprehensive and certified: CE (LVD, EMC, RED), UKCA, compliance with IEC 61851-1/23, IEC 62196, and ISO 13849, AC-side Type II surge protection, Type A RCDs with 6mA DC fault detection, DC-side insulation monitoring, per-gun contactor weld detection, emergency stop, and remote de-energization. IK10 impact ratings on cabinet and screen glass resist trolley, vehicle, and vandalism impacts.

Reliability engineering focuses on the unattended duty cycle: intelligent forced-air cooling with variable-speed fans, conformal-coated electronics, conservative component derating, and a 10+ year design life. All serviceable parts are modular and field-replaceable; remote diagnostics provide fault alerts and over-the-air firmware updates. For a portfolio operator without technical staff on site, the IP55 unit is designed to be installed, connected, and forgotten — monitored and maintained remotely.

5. Smart Management and Connectivity

Portfolio operation demands centralized management, and the MIDA platform delivers it. OCPP 1.6J (2.0.1 optional) connects every unit to any compliant backend; connectivity is redundant (4G LTE/5G-ready, Wi-Fi, Ethernet, RS485) with offline session handling. Authentication supports RFID, QR, app, and Plug & Charge — the operator chooses per site.

The backend dashboard provides portfolio-wide visibility: live sessions, energy, revenue, utilization, faults, and media impressions, with exportable reporting and role-based access for multi-team operations. Remote operations include firmware updates, tariff configuration, power limits, and load management across sites. For a restaurant chain, this means one dashboard covering 40 sites; for a CPO, one dashboard covering hundreds.

The advertising CMS runs on the same connectivity, logically isolated from charging: campaigns play from local cache during outages, and media never affects charging availability. Engagement analytics feed advertiser reporting automatically. The platform’s reporting integrates with finance systems, giving the operator a single source of truth for energy, media, and maintenance — the operational backbone of a profitable commercial portfolio.

6. Detailed Technical Specifications

This specification defines a volume-deployable commercial charger: IP55 outdoor protection, interactive media surface, dual power tiers on one platform, and full management integration — the attributes that make portfolio-scale deployment predictable and profitable.

7. Use Cases & Installation

The 60/120kW interactive charger deploys across commercial portfolios:

1. Restaurant & Quick-Service Chains — 60kW units in store parking serve 30–60 minute dining dwell; the touchscreen promotes menu items and loyalty offers; sponsorship covers part of the operating cost.
2. Hotels & Hospitality Groups — 60–120kW units in guest parking; the screen promotes amenities, local attractions, and packages; app and QR charging integrates with the property’s booking system.
3. Parking Garage Operators — 120kW dual-gun units on prime levels; the screen shows wayfinding, garage promotions, and partner ads; load management coordinates units on constrained garage feeders.
4. Retail Franchises & Convenience Stores — 60kW units at fuel-and-convenience sites; the interactive screen drives in-store traffic with redeemable coupons; the IP55 rating handles 24/7 forecourt exposure.

Installation is the lowest-friction path to commercial fast charging: a concrete pad or reinforced base, an AC feeder (often existing supply for 60kW), and commissioning — connectivity, backend registration, tariff configuration, and a full-power test. Typical install time is 1–2 days. The integrated cabinet requires no canopy or separate distribution unit, and the IP55 rating means no additional weather protection is needed.

Operationally, expect 4–12 sessions per day in year one at destination sites, scaling with EV adoption. Maintenance is quarterly inspection plus annual service; firmware, tariffs, and content updates are remote. For the portfolio operator, the combination of volume pricing, one management platform, and per-site media income makes the 60/120kW interactive charger the rational choice for scaling commercial charging profitably.

8. FAQ

Q1: Why offer both 60kW and 120kW on one platform? Because commercial portfolios mix site types. 60kW serves destination sites with longer dwell and limited grid; 120kW serves higher-turnover sites. One cabinet platform, one spare-parts pool, one training program — configured per site.

Q2: What does IP55 actually guarantee? IP55 certifies dust protection (level 5) and water-jet protection from any direction (level 5) — the benchmark for outdoor commercial installation. The display housing is IP65, and both carry IK10 impact ratings.

Q3: How does the interactive display generate revenue? Through sponsorship packages (€100–€1,800 per site per month at typical fill), network packaging across multiple sites, internal promotion value, and premium CPMs for interactive inventory with verified engagement data.

Q4: Can drivers interact with the screen safely? Yes — projected-capacitive touch works with gloved hands and rejects water droplets; the touch layer is behind IK10-rated glass, and interactive content is separated from charging status in split-screen mode.

Q5: Is this charger compatible with all commercial vehicles? Yes — 150–1000V output serves 400V and 800V architectures, connector options cover CCS2, CCS1, GBT, and NACS-ready configurations, and OCPP 1.6J connects to any compliant backend.

Q6: Can one dashboard manage a whole portfolio? Yes. The backend provides network-wide session, energy, revenue, fault, and media reporting, with remote configuration and over-the-air updates — one operator managing dozens of sites from one screen.

Q7: What is the payback for a typical commercial site? Charging revenue plus media income at a well-positioned site typically supports payback in 3–5 years; media income often covers 15–30% of total operating cost from year one, and internal promotion lifts the core business further.
