Design Consideration for Battery SystemDesign Consideration for Battery SystemDesign Consideration for Battery System
放電能力 (Discharge Ability)•
How much energy is available in the storage ?
•
With what power can LEV draw this energy from the storage ?
•
May LEV still perform a certain (critical) function relying on the storage ?
•
How long can LEV still continue drawing a certain power ?
充電能力 (Recharge Ability)•
How much energy can I still store into the storage ?
•
How fast (with what power or current) can I store energy into the storage ?
•
What will be my energy losses under different charging conditions ?

DesignDesign--related Definitionsrelated Definitions--11
Anode (陽極):The electrode at which an oxidation reaction occurs. Usually, a cell’s anode is specified during discharging and hence the name anode is commonly used for the negative electrode. Cathode (陰極):The electrode at which a reduction reaction occurs. Usually, a cell’s cathode is specified during discharging and hence the name anode is commonly used for the positive electrode.

Electrolyte:The medium that provides the essential ionic conductivity between the positive and negative electrode of a cell.Separator:An ion-permeable, electronically non-conductive material or spacer that prevents short-circuiting of the positive and negative electrodes of a cell.
