Ricardo Establishes Center for Development of
Battery Systems for Hybrid and Electric Vehicles

Release date: 18 March 2008

Battery Systems Development Center will feature large HEV/EV-capable battery cyclers, will specialize in turnkey vehicle battery systems development

VAN BUREN TWP., Mich., U.S.A. (MARCH 18, 2008) – Ricardo, Inc., a leading independent engineering firm specializing in total vehicle fuel economy and efficiency, has announced the establishment of the Battery Systems Development Center at its Van Buren Twp., Michigan, headquarters to offer turnkey engineering and development of complete high-voltage battery-pack systems for hybrid (HEV), plug-in hybrid (PHEV) and electric vehicles (EV). The center will feature three lithium-ion (Li-Ion)-capable development chambers, large HEV/EV-capable battery cyclers and equipment to facilitate the development of battery systems in simulated vehicle environments. The Battery Systems Development Center will be used to validate Ricardo’s design, analysis and simulation of advanced high-power battery packs. This, combined with the company’s pack/vehicle integration, hybrid transmission development and vehicle development capabilities, puts Ricardo in a
unique position of being able to provide turnkey vehicle battery systems development.

"Electrification of the vehicle is a critical element of automakers' strategies for reaching 35-mile-per-gallon CAFE regulations," said Ricardo President Dean Harlow. "Up to half the development cost of a battery system can be the robust integration of battery cells into packs. As a leader in advanced vehicle technology, Ricardo is applying its Total Vehicle Fuel Economy™ (TVFE) capabilities to this important new technology to help our customers accelerate the volume production of electric vehicle technologies into the market. Hybrid, plug-in hybrid, and electric vehicles are fast becoming a crucial part of the technology mix, and we have the experience of more than 30 hybridvehicle and battery-systems projects to draw upon to bring even more value to our customers."

The Battery Systems Development Center, projected to grow to a staff of 32, will focus on engineering complete Li-Ion and nickel-metal-hydride (NiMH) battery-pack systems (as opposed to the development of battery cells, which is the domain of cell manufacturers).

"There are critical items to address, such as control algorithm robustness, accurate state-ofcharge estimation, fault-tolerance design, thermal management optimization, shock and vibration robustness and cost management" said Wayne Thelen, Ricardo’s Chief Engineer for Advanced Technology. “Ricardo has the engineering expertise to meet these challenges. Our TVFE simulation, control, and optimization capabilities are extremely accurate in setting the parameters for battery-pack design. The development chambers will validate these designs in real-world tests, assuring maximum performance and efficiency in this important new technology."

Prototype pack systems will undergo exhaustive development in three specially built development chambers equipped with robust safety and filtration systems. Each will feature highcapacity EV/HEV-capable battery cyclers, high-voltage instrumentation, hardware-in-the-loop systems and other equipment to enable the development of battery systems in simulated vehicle environments. Once a battery pack design is verified in a safe, simulated environment, the battery system can be integrated into and further developed on a vehicle in Ricardo’s adjoining garage
facility. The first chamber is scheduled to be commissioned by mid-summer 2008.
