Efficiency & Sustainability

Why GEBAT chargers are the superior choice for your bottom line and the planet.

In the world of industrial electric vehicle charging, conversion efficiency is often cited as the most vital parameter. With many manufacturers claiming efficiencies above 90%, the industry has reached a high level of technological maturity.

GEBAT consistently leads this field: our flagship BBX models reach a certified efficiency of 97.4% (verified by the independent body TÜV SÜD)—a benchmark we have yet to see surpassed by any competitor.

  • GEBAT CONVERSION EFFICIENCY: 97.4% 97.4%

However, when evaluating the true economic and ecological impact of a charger, it becomes clear that electrical efficiency alone is only part of the story.

The energy loss during operation (inevitable in any system) is just one factor contributing to the Total Cost of Ownership (TCO) and overall sustainability, and it is often not the most decisive one. 

While modern efficiency gaps of a few percentage points result in minor utility savings, other factors have a far more radical impact on your operating costs and environmental footprint.

Engineered
service life

Design longevity is the essential parameter that dictates every engineering choice we make.

A highly efficient but fragile charger that requires replacement after a few years is far more costly than a robust system designed to remain operational for decades.
From an environmental perspective, the production, transport, and disposal of raw materials weigh much heavier than minor efficiency variances.

BASSI/GEBAT chargers have always been conceived to last decades, even in the most strenuous applications. With the new BBX series, we introduced a FULLY MODULAR ARCHITECTURE:

  • Independent Power.
    Control Modules: Not only the power electronics but also the control, interface, and communication sections are individually replaceable.
  • Field-Serviceable.
    Replacements and reconfigurations can be performed on-site in minutes without specialized tools.
  • Redundancy.
    In the event of a module failure, the charger continues to operate (at full or reduced power depending on configuration), ensuring zero downtime.
  • Remote Management.
    WiFi-enabled diagnostics, monitoring, and firmware updates prevent premature obsolescence.

Current
stability & battery
health

Ideally, charging current should be continuous and free of residual ripple. While many modern chargers show “clean” curves on standard multimeters, high-resolution oscilloscopes often reveal excessive ripple levels.

Even when the average current value appears correct, these hidden oscillations:

  • Increase internal battery losses (Joule Effect), spiking operating temperatures.
  • Degrade battery performance and shorten service life.
  • Erode the overall system efficiency in ways that are difficult to measure without specialized lab equipment.

In recent comparative tests between GEBAT (BBX and HPS models) and leading competitors, we measured the Peak-to-Peak Current Ripple:

This massive disparity directly impacts battery health and operational costs.
The GEBAT advantage goes far beyond the electric bill.
It protects your most expensive asset: the battery.

Modern design & sustainable materials

The “produce-use-dispose” model is no longer viable. Electronics require “critical minerals” whose extraction is environmentally taxing.

A truly sustainable approach requires circularity: designing products from day one to be repairable, upgradable, and recyclable.

Excessive use of plastics is a global challenge; they are cheap but often non-recyclable. GEBAT has replaced plastic components with steel and infinitely recyclable metals wherever possible.

Our Circular Economy Principles:

  • Minimizing Rare Earths.
    Reducing reliance on critical and conflict minerals.
  • Optimized Mechanical Design.
    Specifically engineered for easy material separation at end-of-life.
  • Metal-Centric Construction.
    Almost entirely free of plastics, favoring durable, recyclable alloys.
  • Global Compliance.
    Fully compliant with WEEE and RoHS directives and international best practices.
