THE HYBRID ADVANTAGE

The basic components of a Hybrid Assist system – such as Mecc Alte’s Hybrid ONE solution - are virtually identical to a traditional hybrid system. A variable speed engine to provide power, a battery to store energy, a Permanent Magnet DC Alternator to provide electrical energy to both the load and the battery, and an intelligent control system that’s capable of controlling both the engine and the hybrid system.

The way in which these components work together is the key difference compared to traditional hybrids. The engine is expected to run for much longer periods to both supply the load and recharge the battery. In some cases, the engine may even be running constantly. So, while the battery may be used as a power source for short periods, it is more often used to boost energy available to the load during peak demand.

This means that smaller and cheaper engines can be used, which reduces overall fuel consumption and – if carefully sized - may also avoid the need for expensive aftertreatment packages. The availability of a pure battery-only mode can bring further operational advantages to the equipment and reduce fuel consumption even more. The use of smaller batteries can also help to offset capital equipment costs.
