Lithium-ion technology targets portable power: SPECIFYING, TESTING, AND MONITORING A BATTERY PACK

摘要

WORK CLOSELY WITH YOUR LITHIUM ION-CELL MANUFACTURER AND BATTERY-PACK-DESIGN HOUSE TO DEVELOP SAFETY AND PERFORMANCE FEATURES FOR YOUR SYSTEM'S BATTERY PACK. A typical laptop-computer battery pack can contain more than 50 Whr of energy and requires care in its design, construction, and operation to ensure that it remains safely within its operating limits. Few circuit-design engineers want or need to become battery experts, yet they must ensure that a system's battery pack can safely perform its tasks and that the host system can monitor the pack during operation. To address these constraints, you must understand how to specify a battery pack, what type of test and inspection it requires, and how the application monitors the battery pack's health during operation.
