IEEE 1625-2008 pdf download IEEE Standard for Rechargeable Batteries for Multi-Cell Mobile Computing Devices
1.1 Scope
This standard establishes criteria for design analysis for qualification, quality, and reliability orechargeable battery systems for multi-cell mobile computing devices. lt also provides methods forquantifying the operational performance of these batteries and their associated management and controlsystems including considerations for end-user notification, This standard covers rechargeable battersystems for mobile computing. The battery technologies covered are limited to Li-ion and Li-ion polymer.but future versions of this standard may include technologies that are not in general use at present. Alsoincluded are: battery pack electrical and mechanical construction; system, pack, and cell level charge anddischarge controls; and battery status communications. The following are addressed: qualification process:manufacturing process control; energy capacity and demand management; levels of management andcontrol in the battery systems; current and planned lithium-based battery chemistries, packagingtechnologies,and considerations for end-user notification.

3. Definitions
For the purpose of this standard, the following terms and definitions apply, The glossary in Annex F andThe Authoritative Dictionary of lEEE Standards Terms (B17] should be referenced for terms not defined inthis clause.
3.1 abuse: Use of product in a way that is not intended by the manufacturer/supplier but which may resultfrom unreasonable or malicious humman behavior or unreasonably extreme conditions or environments
3.2 active authentication: A method of qualification of a battery and/or accessory where the system makesthe compatibility decision independent from the end user. For example, the use of a secure memory devicewithin the battery pack that communicates to the host that the pack is suitable for use with a specificOEM’s mobile computing device.
3.3 active charger: A charger that has a communication channel and interacts with the host device.
34 adapter: A device that transforms the available power from an external source (for example, ac walloutlet, airline, or automobile outlets, etc.) to the power used by the host.
3.5 aging of cells: Manufacturing process(es) from initial charge to final acceptance.
3.6 authentication: Any method of qualification of a battery and/or accessory designed to ensurecompatibility with a specific host device.
3.7 battery/battery pack: An assembly of any number of Li-ion or Li-ion polymer cells, associatedelectronics, battery packaging,and connector(s).
3.8 battery management circuit: An integrated circuit that manages battery operation to preventovervoltage, overcurrent, and stops battery operation at set high and low temperatures as well as at a setlow-voltage cutoff.
3.9 burr: A sharp metallic projection at the edge of an electrode foil that may penetrate the separator andcause an internal short in a Li-ion or Li-ion polymer cell.
