Danfoss EDITRON – designing a hybrid or fully electric system has never been this simple
In conventional mobile applications, electricity is produced by diesel generators. Common trait of these systems is that the three-phase generator before the voltage regulator is powered by a diesel engine running at constant speed. Although the engine is operating at optimum efficiency, the same amount of electricity is always generated, even when there is no need from the consumers.
The Danfoss EDITRON system is also built around a diesel engine, but besides the permanent magnet generator and the inverter, it also utilizes a special controller. Based on actual system load, this control unit can regulate engine speed, lowering it when idle-, raising it when peak performance is needed, resulting in much better energy efficiency.
The EDITRON systems offer a power range of 30kW to 2,000kW. A high tolerance to shocks and vibrations means excellent reliability. All components are liquid-cooled, guaranteeing reliability throughout a wide ambient temperature range and broad range of environments. Lightweight and compact, EDITRON saves space and allows for flexibility in installation. The easy-to-use software platform makes system integration quick and easy and takes care of monitoring, diagnostics, and setup. Advanced control software guarantees superior performance in even the most demanding situations.
Serial hybrid is a system where the generators are connected to the internal combustion engine, while the electric motors are connected to the load, with inverters controlling both the generators and motors.
There is also energy storage, typically in the form of a battery, which in certain cases can also act as a single source of power instead of the engine.
In parallel hybrid systems, there is one electric machine that acts as either a generator or motor, depending on the operation point.
This machine is connected to the internal combustion engine while the load is connected to both the engine and the generator.
The electric machine is also connected to the energy storage via the inverter, which controls when the energy storage is charged (generator) and discharged (motor).
This energy storage unit can be also used for support. In situations when the load is higher, reducing the load and peaks is handled by the internal combustion engine and recharges when the load is lower.
A fully electric (zero-emission) system consists of energy storage, inverters and electric machines running loads (wheels, hydraulic pumps, etc.).
Energy storage is usually charged from the grid and used to feed the load, while inverters are used to control the machine running the load.
Energy recovery is possible from braking or other deceleration functions.
