ISE and Altair Nanotechnologies in Joint Development Agreement for Li-Ion Packs for Heavy-Duty Vehicles
1 June 2007
ISE Corporation, a developer and manufacturer of electric and hybrid-electric drive systems and components for heavy-duty vehicles, and Altair Nanotechnologies (Altairnano) have entered into an agreement to jointly develop and commercially supply lithium-ion rechargeable battery packs for use in hybrid-electric and all-electric heavy-duty vehicles.
Under the agreement, Altairnano will provide NanoSafe cells and batteries for the battery pack based on their proprietary lithium titanate electrode materials, along with data concerning the proper care and management of their cells and batteries.
ISE will design the system utilizing its data on operating environments, vehicle shock and vibration criteria, vehicle duty cycles and proprietary software and control electronics. Other cooperative areas will include cell equalization and packaging of the commercial product. The goal is to develop and commercially supply high quality, cost-effective, lithium battery packs for heavy-duty buses, trucks, military vehicles and airport ground support equipment.
ISE intends to continue to be a leader in the development of energy storage solutions for heavy duty electric and hybrid electric vehicles. We are excited to have partnered with Altairnano and feel that Altairnano's unique nano technology yields power storage solutions with high power and extremely long life that are ideally suited to maximize the performance of heavy duty hybrid vehicles.—David Mazaika, President and CEO of ISE Corporation
Altairnano currently is providing a 35 kWh lithium-ion battery pack for the Phoenix Motorcars all-electric light-duty sport utility truck. (Earlier post.) Separately, AeroVironment announced that it has tested and validated Altairnano and Phoenix Motorcar’s claim that the Altairnano battery can be recharged in less than 10 minutes without harm to the battery.
At the Advanced Automotive Battery Conference 2007 (AABC), Altairnano described its work on developing new battery modules optimized for the differing application requirements of hybrid-electric (HEV) and plug-in hybrid electric (PHEV) vehicles.

Earlier in May, lithium-ion battery maker A123Systems announced that it had entered a partnership with BAE Systems to provide li-ion battery packs for BAE’s heavy-duty HybriDrive. (Earlier post.)
ISE recently announced the sale of 150 gasoline hybrid-electric buses to Montebello, California. (Earlier post.)
