The Vanner Hybrid Beltless Alternator (HBA) is Unveiled with the Allison Transmission Hybrid System on the Orion VII Transit Bus

The Vanner Hybrid Beltless Alternator (HBA) replaces the alternator on the Orion VII Transit Bus to save energy, reduce maintenance and increase vehicle readiness.

The Vanner HBA is a basic foundational building block for energy efficient vehicle electrification.

Visitors to APTA’s Expo in New Orleans will see the Vanner Hybrid Beltless Alternator at the Daimler Buses North America (DBNA) exhibit. The Hybrid Beltless AlternatorTM (HBA) is installed on the Orion VII transit bus with an Allison Transmission Hybrid System.

The Vanner Hybrid Beltless AlternatorTM (HBATM) is a solid-state devise that converts a portion of the hybrid’s “green” electrical power to electrify the bus with a 24 volt electrical system. Vanner joined the DBNA partnership in 2010 when they announced the release of the Allison Hybrid for the Orion VII transit bus.

The HBA converts 600 volt DC from the hybrid propulsion system to 24 volts DC. The HBA replaces the traditional, large, belt-driven, mechanical alternator that has increased in size over time as bus technology has advanced and more electrical features have been added to the transit bus.

The HBA is a cost effective power alternative since it means you can eliminate the alternator, regulator, V-belts, pulleys, tensioners, and hydraulic cooling lines from a transit bus’ engine compartment.

The HBA produces full power at idle with electrical efficiencies of 92-96%. The cool running design produces ripple-free power to recharge the bus’ batteries while powering the bus’s electrical system.

The HBA enables vehicles to expand “electrification” by powering the electric radiator fans and communicating with the bus via SAE J-1939.

When the HBA is used with the new Vanner Vann-Bus Series-80 Equalizer, the 12/24 volt batteries are dynamically regulated to precisely control the rate-of-charge of the bus in order to extend their life.

“The Vanner HBA is a basic foundational building block for energy efficient vehicle electrification,” said Chris Collet, Vanner VP of Bus and Hybrid Markets. “It is expandable with the Vann-Bus Equalizer for ‘dynamic’ regulation of the bus’ batteries. By communicating data over J-1939 for customers, it monitors state-of-health data with automatic vehicle monitoring systems. This assists the bus companies with energy efficiency, maintenance cost reductions and vehicle readiness.”
