Bolt-On Ultracap SystemsCould Yield Fuel Savings as Great as 30%
Crosspoint Kinetics, a new unit of Cummins Crosspoint, is promoting a third-generation parallel hybrid electric retrofit system for small paratransit, shuttle bus, and package delivery applications. The new S3000 is based on designs acquired from VTM, Variable Torque Motors, says marketing director Rob Higley.
The S3000 “leverages evolved designs and technologies with improvements in durability and control software,” the company says.
“We have addressed many of the problems with first-generation hybrids, such as expensive batteries, less-than-satisfactory reliability, and complex integration into a vehicle,” Crosspoint Kinetics product director John McNichols says in a release. The unit is easy to install and remove, the company says, is compatible with gasoline, diesel, propane, and compressed natural gas engines, can be installed in new and used vehicles, and “even transferred from one vehicle to another.”
First-Generation ‘Inflexibility’ Addressed
“By addressing the inflexibility of first-generation systems, we have made it easier for operators and customers to participate in the greening movement toward alternative fuels,” McNichols said.
Results from third-party and field testing have shown fuel economy increases ranging between 10% and 30%, Crosspoint Kinetics says – varying by driving style and route selection.
The system “offers a choice of extra acceleration or fuel economy performance depending on how the operator wants to use it,” McNichols said.
Maxwell, Nidec, ZBB
The S3000 includes ultracapacitors by San Diego’s Maxwell Technologies, motor manufactured by Nidec in its Princeton, Ind. (Hurst Motors) facility, and control computer and inverter from ZBB Energy of Menomenee Falls, Wisc.
Crosspoint Kinetics says it’s working directly with key OEM bus and chassis manufacturers to ensure quality installations.
“We have successfully completed system-life, performance, reliability, and FTA/Altoona testing,” McNichols said. “We are confident our second-generation hybrid will perform and bring many benefits to the communities where they operate.”
The S3000 drive is in limited production now, with full production expected to commence during this fourth quarter of 2013.
