Danfoss' Editron ED3 onboard charger and electric power take-off (ePTO) has now been standardized with communication protocols, software, and documentation for off-highway applications. The ED3 enables rapid overnight and opportunity charging for heavy-duty electric machinery using readily available ac chargers. Its three-in-one functionality — ac charger, dc ePTO and ac ePTO — reduces complexity and streamlines machine design and integration. The Editron ED3 onboard charger and ePTO is ideal for medium- and heavy-duty trucks and off-highway machinery, such as excavators, large tonnage tractors, wheel loaders and more. It also is ideal for machinery used in areas where high-voltage DC charging is uncommon or not practical. The ED3 supports a wide range of global grid voltages, enabling broad deployment.
The Danfoss Editron ED3 can deliver up to 44 kW of power to a machine’s main high-voltage battery, which halves charging time, minimizing machine downtime. This power level can fully charge heavy-duty electric vehicles overnight using ac chargers. It also minimizes charging infrastructure costs by eliminating the need for dc chargers, which can cost up to 10 times more to procure and install than ac chargers.
The ED3’s high-power dc and ac electric power take-off simplifies machine design and integration. The device pulls power directly from the main high-voltage battery to provide up to 44 kW of dc power to auxiliaries, such as high-voltage compressors, pumps and motor controllers. The ED3 also can convert power and deliver up to 43.6 kVa of single- or three-phase current to create an AC microgrid for plug-in functions in the field. The electrified PTO decouples auxiliary functions from the vehicle’s driveline and frees space on the vehicle chassis for batteries and other components, easing installation. Electric PTOs also minimize mechanical losses, resulting in higher efficiency.
