Heavy-duty vehicles have many potential energy storage devices that can be part of a hybrid system if appropriately controlled. Excess capacity creates an opportunity to augment the vehicle braking system and run the accessories when low-cost energy is available. With the addition of control logic, these elements can work in unison to store and release vehicle kinetic energy to further offset fuel usage.

• Engine/System Fans – Thermal energy storage

• AC Compressor – Compressed air storage

• 12/24V System – Electrical energy

​DCS’s Intelligent Accessory Control will:

• Realize efficiency gains through load management

• Prioritize load scheduling based on accessory power consumption and available power from the vehicle

• Provide seamless integration with multiple bolt-on options

• Manage interdependencies of multiple subsystems

• Take advantage of low-cost energy when available to drive accessories

• Adapt control algorithms to driving conditions and accessory usage

• Take advantage of synergies that exist at a system level to optimize control

• Apply solutions that enable retrofits for older systems
