Regenerative
Braking For
the STRIKER^®
VOLTERRA^™

What is Regenerative Braking?

As opposed to friction brakes where kinetic energy is converted to heat to slow the vehicle, the Striker Volterra ARFF has standard regenerative braking which instead converts kinetic energy to electrical energy stored in the high-voltage (HV) Battery. The result is less heat and wear on the vehicle service brake system as well as further reduction in fuel and electricity consumption.

How Does Regenerative Braking Work on the Striker Volterra ARFF?

The integration of regenerative braking on the Striker Volterra ARFF is seamless. Slight regenerative braking is engaged on deceleration to simulate the drag present in conventional apparatus. The driver has the option to activate the regenerative brake switch to add additional regenerative braking on deceleration. Finally, when the service brake is initiated, maximum regeneration is activated as needed.

Does Regenerative Braking Work Differently in an ARFF Vehicle Compared to a Standard Passenger Vehicle?

Regenerative braking is implemented in a way that the driver will have similar functionality as conventional apparatus. The UI (user interface) is similar to options for exhaust brake, for example, as found on a conventional apparatus. The result of the functionality is integrated in a way to make the experience seamless to the driver.

What are the Benefits of Regenerative Braking on the Striker Volterra ARFF?

Key benefits of regenerative braking include reduced brake temperature and wear as well as reduced fuel consumption which enhances overall efficiency.

How Does Regenerative Braking Reduce Component Temperature and Wear?

This is achieved by converting the kinetic energy of the vehicle to electrical energy for later use as opposed to friction brakes which convert that same energy to heat which is wasted to the environment.

Regenerative Braking is Known to Decrease in Effectiveness at Low Speeds. Does the Striker Volterra ARFF Typically Reach Speeds that Justify System Benefits?

Regenerative braking on the Striker Volterra ARFF is designed to provide a consistent and predictable feel to the driver. If the regenerative braking is not ramped down as the vehicle comes to a stop, a harsh driving experience may result.

Are There Any Operational Differences for an ARFF Crew with Regenerative Braking?

Regenerative braking is integrated in a way to seamlessly fit in to the operational profile of the ARFF vehicle. UI elements are effectively identical to the conventional vehicle with an exhaust brake. The driver will notice that the application of regenerative braking is smoother and offers more controllability as they become accustomed to the system.

What are the Safety Benefits of Regenerative Braking on the Striker Volterra ARFF? 

By carrying a portion of the brake load during aggressive stops, brake temperature is reduced. This may result in a lower incidence of brake fade.
