Battery Power Management: Safety, Charging, Fuel Gauging, and Cell Balancing

Presented by: Jinrong Qian, Texas Instruments
Time: 1:00 p.m. to 4:00 p.m.
Registration: Before September 17th: $99; after September 17th: $149

This workshop addresses the issues surrounding battery power management for safely charging the battery, smartly monitoring the battery for improving protection, and accurately estimating battery remaining capacity, cell balancing from handheld, Laptop, power tools, e-Bike, electric vehicle, and medical applications.

The first part of the presentation provides the battery electrical behavior, charging and discharging characteristics, cycle life and safety protections including over-charging, over temperature, over-current and short circuit for Li-Ion and LiFePO4 batteries.

The second part is going focused on how to accurately monitor the battery remaining capacity. We are going to review the most commonly used monitoring approaches: coulomb counting, voltage measurement based and 99 percent accuracy impedance track based fuel gauges. The seminar will be focused on the cell-balance techniques for multi-cell series batteries. Single cell, multi-cell, and high–cell fuel gauge examples in hand-held, notebook, power tool, E-bike, and electrical vehicle applications will be presented.

The last part of the workshop will review the battery charging system architecture. Dynamic Path Management (DPM) technology is going to be presented to maximize use of the AC adapter power while charging the battery and supplying the system simultaneously. A practical switching mode charger design considerations and design examples for charging both LiFePO4 and Li-Ion batteries up to twenty-cell in series applications and their battery charging ICs are going to be presented.

This workshop is structured to provide in-depth coverage of the topics in battery powered applications, and is intended for the audience from entry level to intermediate experience level in battery management.

Lithium-Ion Battery Design Tutorial

Presented by: Robert Spotnitz, Battery Design LLC
Time: 9:00 a.m. to 5:00 p.m.
Registration: Before August 18th: $395; after August 18th: $495

This full day course surveys all aspects of lithium-ion battery design ranging from materials and processes, to cells to packs. A thorough overview of the issues involved in life estimation, thermal behavior, and abuse tolerance is provided. How to design lithium-ion cells is discussed in detail with an emphasis on comparing different chemistries. The Battery Design Studio software is used to illustrate design techniques for cells and packs.

This course is aimed at managers, engineers, and scientiests interested in getting a good overview of lithium-ion technology as well as learning how to design lithium-ion cells. No prior knowledge of lithium-ion
batteries is assumed.

This workshop sold out at Battery Power 2009. Register today to reserve your spot.
