Nissan Motor Co. Ltd is using Maxim Integrated Products’ lithium-ion battery monitor for its Nissan Pathfinder Hybrid, a sport utility vehicle for the US market.
The lithium-ion battery system for the Nissan Pathfinder Hybrid is supplied by Hitachi Automotive Systems, Ltd. Hitachi Vehicle Energy, Ltd. developed the system and incorporated Maxim’s IC.
Highly efficient battery
Maxim’s lithium-ion battery monitor provides self-diagnostics and robust daisy-chained data communications that easily handles the high-voltage requirements of the automotive industry. Maxim’s highly integrated solution enables a smaller, lighter weight, and high-performance lithium-ion battery system in the hybrid. Using Hitachi’s battery system with Maxim’s lithium-ion battery monitor IC, the Pathfinder Hybrid achieves greater driving range than competitive systems and improves the overall safety of the battery system.
The hybrid Li-ion battery delivers twice the power compared to similarly-sized conventional cells. As the output of the battery increases, so does the acceleration. It also stores energy more efficiently during deceleration, further improving fuel efficiency.
“Maxim’s battery cell-monitoring IC was integral to achieving the highly reliable, smaller, lighter, and high-power Li+ battery system required for the newest hybrid car,” said Mr. Koji Masui, Department Manager, Lithium Ion Battery Development Dept., Hitachi Automotive Systems, Ltd.
“The automotive market is a major focus for Maxim, and I am pleased that Nissan selected our cell-monitoring IC for its Pathfinder Hybrid,” said Kent Robinett, Managing Director, Automotive Marketing for Maxim Integrated. “Maxim is advancing into a next-generation EV/HEV powertrain system, and we will continue to develop highly integrated products for this important market.”
Maxim, a leader in analog innovation and integration, is unique among semiconductor companies in its ability to integrate extensive and different analog functions on a single chip. Maxim’s highly integrated solutions help customers produce smaller systems with greater energy efficiency.
The Growing Lithium-ion batteries market
Demand for lithium-ion batteries is expected to surge in the next decade with the market growing to a value of US$26 billion annually by 2023. This is according to Navigant Research which points out that the consistent and reliable performance of the lithium-ion batteries, increasingly used in battery-electric and plug-in hybrid cars, will see annual revenue increase roughly four-fold, from less than US$6 billion in 2014.
“The shift to lithium represents a major endorsement of the ability of this chemistry to perform consistently in an automotive environment,” said senior research analyst, David Alexander. “Most of the major automakers have introduced battery electric vehicle and plug-in hybrid vehicle models in the last two years, almost all of which use lithium-ion batteries for onboard energy storage.”
Perhaps the largest single contribution to lithium-ion battery totals will be Tesla’s ‘gigafactory’, which is due to become operational in 2017, in time for the cut-price Model E sedan. Running at maximum capacity, the 500,000 battery packs the US$4.5 billion facility will be capable of producing could represent half of all units made each year worldwide.
