This document describes how the LTC6802 multicell battery stack monitor extends the life of lithium-ion batteries in hybrid electric vehicles. The LTC6802 is a core component in battery management systems for lithium-ion batteries.
The document discusses the importance of a Battery Management System (BMS) for maximizing the performance and lifetime of Lithium-based chemistries used in Hybrid Electric Vehicles (HEVs). It highlights that high performance is not guaranteed simply by design, but requires accurate cell-level management.
The LTC6802 multicell battery stack monitor is presented as a central component to any BMS. The text details how the device can precisely measure voltages of up to 12 series-connected battery cells and mentions its capability for stacking multiple units in series without optocouplers or isolators.
The LTC6802 is a highly integrated multicell battery monitoring IC capable of precisely measuring the voltages of up to 12 series-connected battery cells.
Using a novel stacking technique, multiple LTC6802s can be placed in series without optocouplers or isolators.
