Nailboard and 3D CAD

Thermal management design

Intelligent control system design

High voltage system design

We use field-proven practices in the system architecture and protection design.

Schematics design

The documentation we provide is ready for series production.

Wire harness design

Correct wire and connector selections are key elements to guarantee long lifetime in challenging environments.

Nailboard and 3D CAD

Our documentation is fine-tuned with multiple manufacturers to get the harness right the first time.

3D routing to the chassis helps avoid wrong lengths and EMC issues between logic level signals and HV.

Thermal management design

We have long-term knowledge of the actual losses components produce in different duty cycles.

We select only reliable and cost-efficient cooling components.

Intelligent control system design: Software, Hevtec VCU

The control functions and interfaces to the components we have developed are scalable and modular. With experience from 70+ machines running, our electric powertrain control SW has evolved into robust and easy to adapt into any new application.

Thermal Management

Proper thermal management for energy storage, power electronics and electric motors enables optimal performance and maximizes the lifespan of the components.  

We are experienced in engineering the optimal parameters for each electrical powertrain thermal management system we design, keeping in mind the machine use-case and working environment. 

Electrical Engineering

Hevtec offers a variety of electrical engineering services to support our customers in designing for safety, compliance and reliability.  

In addition to high voltage schematics, wire harness and cable routing design in 3D, we typically engineer logic level schematics and document the resulting, readily-reproducible, wire harnesses.  

This supports fast customer implementation of the electrical powertrain, regardless of complexity. 

Precision Engineering Solutions for the Electrical Heavy Machinery

Our core expertise lies in the engineering, development, and testing of robust electrical powertrain solutions and energy storage system integrations for the most demanding applications.  

With nearly two decades of practical electrification work with electric construction machinery, our engineers bring deep insight into real-world performance, durability, and integration challenges. Electrical system integration plays a key role in overcoming those challenges and ensuring the success of electrification projects.  

As the project manager from our strategic partners puts it:  

“Staying on schedule is also influenced by component expertise – understanding how they work and what challenges they may present. This allows us to anticipate issues and account for every detail in advance.”

Electric Components Optimized to Your Machine’s Requirements

We select each component based on its functionality and fit for the application. While we work independently of brands and suppliers, we collaborate with a trusted network of proven partners to ensure quality and reliability.  

Global Supplier Network for Added Value

We have been carefully developing a Global Supply-Chain Ecosystem with a wide network of contacts to renown component manufacturers, adding technical, economic and sustainability value to our customers. 

Development and Design

We select the most suitable powertrain components for each machine by analyzing duty cycle data gathered during the Solution Assessment phase – and by applying over 18 years of hands-on experience in electrifying a wide range of heavy machinery platforms.
