Ponsse launches an electric forest machine

Ponsse and Epec are introducing the PONSSE EV1, an electric forest machine technology concept. While the forest machine will be commercially available later, Epec’s technology can already be used in electric or hybrid-electric commercial vehicles and non-road mobile machines. Ponsse’s technological concept is a peek into the future, paving the way for technological development and sustainable harvesting solutions.

The PONSSE EV1 concept has been developed for forwarders with a 15-tonne load-carrying capacity, the most popular Ponsse forwarder size category. The concept machine features a fully electric powertrain, as well as Epec’s power distribution unit and hybrid control unit. The machine’s powertrain operates fully with battery energy.

Batteries are charged using a Range Extender, which is a combustion engine at this stage of development. Testing and development are advancing continuously. This technology provides significant improvements in fuel economy in this size category.

Ponsse has been studying and developing new technological solutions for several years now. The PONSSE EV1 concept took its first steps in 2019 when Ponsse and Epec started to investigate responsible power source solutions in line with sustainable development.

The PONSSE EV1 features Epec Flow, Epec’s electromobility system solution. The solution is based on the Epec Flow Power Distribution Unit (PDU), to which electric motors, batteries and various devices can be connected. The PDU’s integrated safety solutions enable effective manufacturing and maintenance of the machines, as well as their operations in demanding conditions. The Epec Flow Hybrid Control Unit (HCU) controls the electric powertrain and includes software developed through simulations, enabling optimal energy consumption, productivity and usability.

“The Epec Flow solution is at the heart of everything. It has been developed for the electrification of various commercial vehicles and non-road mobile machines. The software can be developed using simulation models, and the solution can be agilely developed for the needs of different machinery. The different systems, including the transmission and control system, work seamlessly together, enabling the manufacture of safe and efficient zero-emission machines in the future,” says Jyri Kylä-Kaila, Managing Director of Epec.
