Energy Management


Dewey provides best in class battery monitoring and charging capabilities that are incorporated in our hybrid generators. Dewey can provide battery chemistry selection choices to the user, resulting in the most efficient battery solution for the system application. We integrate renewable and sustainable energy sources into your power system, resulting in significant fossil fuel saving.

Energy management encompasses energy storage, and renewable, sustainable, and alternative energy sources. Dewey implements these features into our controllers and power systems.

Our hybrid power system has been designed to accept and control energy from solar, wind, and other alternative energy sources. We have implemented inverters into power systems to support battery charging and conversion of DC energy from renewable sources to AC power.

Energy storage (batteries) is a key component of energy management systems. Battery selection and battery chemistry are selected based on the application of the system they are going into. Certain chemistries provide high energy outputs, and others provide high power outputs. Some applications may require a selection of both high energy and high power batteries. Dewey engineering can assist you in making the correct selection for your application.

Battery charging is also essential in energy management systems. How battery charging is managed is important in storing energy and maintaining battery life. Dewey has developed the controls that address the special needs of AGM and Li-Ion battery chemistries during charging that help to extend battery life.

Our engineers work with our customers to determine the optimum energy storage device (battery, ultra capacitor, etc.), recommend the battery chemistry, and provide guidance in battery monitoring and charging to match the energy source with storage technology, resulting in an integrated energy solution that meets the total requirements of the user. Our knowledge of battery charging and battery chemistries allows us to manage the energy storage in the most efficient manner, providing power when needed and extending battery life.

Integrating multiple sources of energy, fossil fuel generators, solar, wind, or other alternative or renewable energy sources efficiently and seamlessly provides the user significant life cycle cost savings, provided the control system is designed with optimizing energy storage as a key parameter. Taking advantage of alternative energy to charge batteries when these renewable sources are most efficient and then relying on fossil fueled generators when they provide the most fuel efficient operation are key considerations in the systems that Dewey designs.

Battery monitoring to determine when to recharge the battery and charging to the proper level not only assures that the power is readily available but also extends battery life. Dewey uses a number of different techniques to monitor the battery, including system voltage, state of charge, and other algorithms based on the system use. We effectively balance battery life with charge cycles to provide the greater life cycle utilization from the energy storage system.
