Vanner's Independence is a simple, compact system designed for CNG- and diesel-powered buses and coaches that provides the majority of the benefits of hybrid and battery-powered buses without the upfront costs and expensive hybrid battery replacement. This single-belt electric system completely decouples accessories such as the alternator, air conditioning, power steering, and air compressors from the engine, significantly increasing efficiencies by operating electric powered accessories independently of engine speed, thus decreasing fuel usage and emissions with an added benefit of lower NVH for passenger comfort. Plus, Independence greatly reduces operational and maintenance costs.
Unique to the Independence is Vanner's Model Based Battery Monitoring (MBBM) that can dynamically charge the batteries and provide a low SOC disconnect feature.
