Managing large Li--ion batteries for maximised performance

March 20, 2013 // By Mike Kultgen, Linear Technology
In this video clip on Linear Technolgy's website, the company's Mike Kultgen describes the latest strategies for handling 16kW-hr battery packs made from lithium ion cells that are powering electric vehicles and storing grid energy.

Measurement ICs like the LTC®6804 are used to extend the life and ensure the safety of the pack. The accuracy of the measurement IC can influence the cost of the system. The LTC6804 can measure cell voltages with less than 1.2 mV of total error. Groups of LTC6804 ICs can measure 100’s of cells quickly and accurately in noisy conditions. Accurate measurements mean fewer battery cells are needed to meet an energy storage requirement.
