DENSO Develops Li-ion Monitoring Unit; Applied in Prius PHV

12 January 2010

DENSO Corporation has developed its first battery monitoring unit for lithium-ion batteries used in vehicles. DENSOâ€™s new battery monitoring unit utilizes a newly developed voltage control method that uses a simpler and lower cost voltage control circuit, compared to the widely used voltage control method used in laptop computers and other hardware. The new product is installed in the Prius Plug-in Hybrid, which Toyota introduced at the end of 2009.

A battery monitoring unit detects a batteryâ€™s voltage, current, temperature, and other parameters to enable high-voltage batteries to be used safely and efficiently. Compared to nickel batteries, lithium-ion batteries have a higher energy density, but because lithium-ion batteries consist of multiple cells with fluctuating voltages, it is necessary to control the voltage of each cell.
