2011 SEMA Show, EL SEGUNDO, USA: International Rectifier (IR) is showcasing an advanced energy management system, Evaira, designed to dramatically extend battery life in electric vehicles at SEMA 2011 which takes place at the Las Vegas Convention Center, Las Vegas, November 1-4, 2011.
The performance of a multi-cell battery pack is limited by the differences between the weakest and strongest cells in the pack. IR’s Evaira advanced energy management system (EMS) utilizes rapid bypass equalization ensuring all cells age uniformly by balancing the state of charge (SOC) of all of the cells within a battery system, resulting in a dramatic extension of battery life and significantly improving battery performance. The complete battery management system also features advanced algorithms, balancing, charge and discharge management and shutoff for electric vehicle applications for the automotive, commercial and military segments.
“The efficient and economical electrification of vehicles provides one of the most significant opportunities to reduce our reliance on fossil fuels. With our mission to deliver energy savings through power management innovation, it is appropriate that IR is pioneering a complete battery management system for electric vehicle applications that addresses the shortcomings of existing products on the market today,” said Oleg Khaykin, president and CEO of International Rectifier.
“Unlike alternative solutions designed primarily for consumer applications that require only a few cells, IR’s Evaira EMS brings a new level of sophistication to address the complexities involved with effective management of battery systems used in heavy duty platforms such as HEV and electric vehicles. This market demands a high degree of customization, so in addition to offering a system that optimizes technical characteristics such as capacity, quality, and safety, the technologies have been developed to enable us to use our system-level expertise to quickly and efficiently support our customers’ individual needs,” said Charles Chang, director, IR’s Advanced Development Group.
