Is my EV compatible with Quasar 2?

Quasar 2 can charge all CCS2 vehicles. Bidirectional features depend on the EV manufacturer, with more expected to be supported soon.

Can I manage charging sessions with the Wallbox app?

Yes! You can schedule and manage sessions using the Wallbox app via Bluetooth, Wi-Fi, or 4G, regardless of your location.

How much can I save with the Vehicle-to-Home feature?

You can save up to €1000 annually by charging during off-peak hours and powering your home during peak hours with Quasar 2.

Can I charge my EV using solar energy?

Yes. With Wallbox solar software and a power meter, you can charge with 100% solar or a mix of solar and grid energy.

Does Quasar 2 degrade my battery?

No. Quasar 2 delivers consistent power, which is less stressful for the battery than acceleration or braking.

Wallbox eM4: The Smart EV Charger for Business and Commercial Installations

4 min read

EV adoption across Europe has hit a tipping point. With millions of electric vehicles already on the road and more coming fast, charging infrastructure needs to do more than catch up – it needs to lead.

At Wallbox, we’ve spent over a decade designing smarter, cleaner ways to power mobility. Now, we’re bringing that expertise to business, commercial and semi-public charging environments with the eM4.

Whether you’re operating an EV delivery fleet, managing workplace charging, or offering services for shoppers and guests in retail or hospitality – reliability and scalability are essential. The eM4 is built to meet those needs: delivering a service-ready platform designed for maximum uptime, easy installation, and simplified maintenance – ideal for across high-traffic, multi-user environments across the EU.

Built for the Realities of Commercial Charging

Charging infrastructure is only as strong as the uptime it delivers.

That’s why the eM4 is engineered for reliability. Built on our proven tech and shaped by global partner feedback, our commercial-grade AC charger is designed to maximize uptime, minimize complexity, and deliver a seamless user experience, even in the most demanding environments.

Modular Architecture: Seven field-replaceable modules – including two independent power modules in the eM4 Twin – keep chargers operational, even during maintenance (We’ll dive deeper into this game-changing feature in an upcoming post).
Fast Field Servicing: All modules, including the power modules, can be swapped out in under 10 minutes with standard tools. A plug & play process with no special gear, no commissioning and no long delays.
Smarter Servicing: Error codes are available on the meter display or through the cloud, helping technicians pinpoint issues both remotely and on-site. This minimizes downtime, reduces the need for on-site service visits and lowers costs.

Public charging has to be more than functional. It needs to be dependable, durable, and easy to maintain – day in, day out. That’s where the eM4 stands apart.

Rollout-Ready from the Factory Floor

Installing EV infrastructure can often be slowed down by backend setup, network integration, or branding compliance. The eM4 helps eliminate those barriers with optional factory pre-configuration and customization services.

Factory Pre-Configured: From SIM cards and EVSE IDs to OCPP backend settings, each unit ships ready to plug in and go.
Durable Custom Branding: Logos are printed behind impact-resistant glass, so your charger stays on-brand and professional, no matter the location.

In short: error-free commissioning, fewer surprises on-site and easier coordination between teams.

Power and Intelligence in Every Unit

Efficiency matters in shared-use charging environments. Each eM4 unit delivers:

Dual Socket Charging: two outlets in one unit allow simultaneous charging of two vehicles, without doubling your hardware footprint.
Integrated Load Management (for up to 100 charging points): expand your charging network without major grid upgrades. More capacity, same infrastructure.

Flexible Backend Compatibility

The eM4 is built on open standards and is fully compatible with a wide range of OCPP-compliant backends, giving you the freedom to choose the platform that best fits your needs.

To simplify rollout and reduce setup time, we also offer market-specific bundles with pre-integrated backend partners:

DACH: eM4 is available as a plug-and-play solution with reev, ideal for commercial installations.
Spain: eM4 can be bundled with Electromaps Manager for seamless activation and management.
Other markets: We’re working to expand localized bundle options, get in touch to learn more.

Seamless Installation, Future-Ready Tech

Whether wall-mounted or freestanding, the eM4’s compact form fits seamlessly into modern settings; corporate campuses, hotels, housing developments, or retail parks.

With hardware built to evolve with your technology roadmap:

Plug&Charge hardware ready for ISO 15118
OCPP 1.6J and HW-ready for OCPP 2.0.1
Eichrecht-compliant variants for the strictest metering regulation markets, such as Germany

Who Is eM4 For?

If you manage charging in:

Commercial fleet depots
Condominiums, multi-unit housing
Hotels, supermarkets, shopping malls or retail car parks
Workplaces
Public parking lots

…eM4 is built to streamline your deployment, simplify your operations, and scale with your business.

Why Start with eM4?

Because not all EV chargers are built for the real world. eM4 was designed from the ground up for commercial applications, fast-paced rollouts, and zero-compromise performance. It brings together everything that matters to professional operators:

✔️ High uptime and modular serviceability
✔️ Dual 22kW AC outputs
✔️ Built-in MID-certified metering
✔️ Fully integrated smart energy management
✔️ Optional pre-configuration and branding

It’s not just about energy delivery. It’s about making EV charging smarter, profitable, and scalable across Europe.

The Wallbox eM4 is where future-ready infrastructure begins. Stay tuned for upcoming posts where we’ll dive deeper into key features that give the eM4 its distinctly competitive edge.
