System Partner for Construction & Heavy-Duty Applications

Drive and battery systems for construction machinery – robust, scalable, and ready for mass production.

Construction sites tolerate no weaknesses.
Construction machinery operates where no other vehicle can go – in all weather conditions, under extreme mechanical stress, and with no room for unscheduled downtime. Anyone looking to electrify operations here needs systems that can withstand these conditions – and a partner who understands the demands of the construction site.

Dirt, dust, rock chips – 24 hours.

Construction equipment is constantly exposed to dirt, flying debris, and moisture. Enclosures, connectors, cell modules – everything must remain watertight when conditions outside get really harsh. A failure on the construction site isn’t just a service call. It’s a shutdown.

Vibration and shock – continuous and nonstop.

Excavators, wheel loaders, and heavy-duty vehicles generate vibrations and shock loads that push battery systems to their structural and electrical limits. Cell connections, BMS, cooling circuits – these components require a solution that delivers long-term reliability.

Emissions regulations – becoming stricter, effective immediately.

Stage V standards, downtown driving bans, CO₂ targets – electrification is coming. Those who electrify their fleets now will secure market access for the future. And they’ll need a partner who understands the certification requirements and can help them meet them.

Whether standardized or custom – we understand the demands of the construction site.

There is no room for error on a construction site. Anyone electrifying machinery in this environment needs a partner they can rely on – from the very first prototype through to ongoing series production.

MODUBAT – a standardized battery system that’s modular, scalable, and ready for immediate use

Custom battery systems – for specific packaging and performance requirements

ePowertrain integration – a complete powertrain solution from a single source

Industrialization – scalable series production starting with the first prototype

What qualifies us for the construction site.

01 · No need for an in-house development team

MODUBAT is proven, compliant with industry standards, and available immediately. OEMs in the construction industry get a system that works – without years of in-house development and without having to build their own battery expertise.

03 · 164 MWh in series production. On the road. In the field.

164 MWh of battery capacity in series production – for automotive and off-highway applications. Our test bench in Biberach tests systems up to 1.1 MW, 1,200 V, and at temperatures ranging from −40 to +90 °C. We’ve already proven what we promise.

What construction equipment manufacturers ask.

Can I electrify my entire fleet, which has varying requirements, in a cost-effective way?

Yes – that’s exactly the advantage of our modular approach. MODUBAT can be configured for different vehicle types and performance classes without having to be redesigned each time. This keeps unit costs low and startup times short.

What voltage ranges does Handtmann cover for off-highway applications?

From 48 volts for hybrid applications to high-voltage systems for all-electric heavy-duty machines. Our test bench covers voltages up to 1,200 V – we can test whatever our customers need.

How early should we involve Handtmann in a project?

As early as possible – ideally during the concept phase. The sooner Design for Manufacturing is incorporated into the process, the more robust and cost-effective the final result will be. It is possible to start later, but this will require more changes.
