US lithium-ion battery developer A123 Systems LLC is set to compete with lead-acid in the micro-hybrid cranking with its 12V product line.
The UltraPhosphate™ technology has achieved more than 25% greater cold cranking power (operating at -30c to 50c and offering 900A at -18c) and can outperform lead-acid batteries in industry standard cranking tests, claims the Michigan based firm.
A123’s 12V starter battery uses a system design to not only offer cranking power but also enable brake energy recuperation, increased cycle life, and charge acceptance.
Micro-hybrids require advanced 12V batteries to power start-stop systems and store electricity from regenerative braking.
The battery weighs 10kg, with the system able to facilitate up to 10% efficiency and emissions gain when compared to a conventional powertrain, claims A123.
