Can a battery really perform like an engine?
We put this question to the test with a real-life working machine to explore the potential role of electrification in powering machinery. Perkins engineers undertook the ambitious project of converting a 75 kW diesel-powered telehandler into a hybrid machine, utilising a Perkins 48V battery system to enable electric-only operation.
Design Objectives
The key goals for this transformation were:
The Transformation Process
The telehandler was carefully disassembled, repainted, and rebuilt with Perkins hybrid technology. The system integrates a powerful 55 kW Perkins® 904J-E28T engine, a 20 kW 48V P2 Motor Generator Unit (MGU), a 48V 3.9 kWh battery, an inverter, and a powershift transmission. This comprehensive overhaul resulted in the creation of the Perkins Pathfinder Project.
Introducing the Perkins Pathfinder Project
The Pathfinder Project showcases a hybrid telehandler concept that operates on both diesel and electricity. Converted from a 75 kW diesel model, this remarkable machine features a 48V battery system that facilitates electric-only operation. The project successfully met its original program goals and continues to be used in daily operations at Perkins’ Peterborough site.
Achieving Success
The engineering team achieved their objectives by enhancing the machine's efficiency by ten percent while ensuring it could run solely on electric. The integration of diesel engine start/stop technology further exemplifies the successful implementation of hybrid technology.The Pathfinder demonstrator offers an array of valuable features, ensuring reliable performance and exceptional capabilities, solidifying its role as a staple on the Peterborough site.
