8. Precautions on Design of Note PC, Charger and Battery Pack
8-1. Precautions on Design of Note PC and charger.
①Charge
･ A battery must be charged with constant current-constant voltage.
･ In case of UR18650F, charge current must be below 2.5A/cell.
･ Charging voltage must be set 4.20(+0.03)V/cell.
Concerning charge voltage tolerance of charger, charging voltage must be set below
4.20(+0.03)V/cell. Even if the charger was out of order, charge voltage should not be
above 4.5V/cell.
･ Have pre-charge system in charger.
In case of a battery voltage is below 3.0V/cell, a battery should be charged with pre-
charge that current is below 0.25A/cell. Then a battery voltage reach over 3.0V/cell,
standard charge starts. And if a battery voltage never reach to 3.0V/cell in specified
period (timer), charger stop charging.
･ Have full charge detection in charger.
By timer, current detection and open circuit voltage detection, charger detects full
charge. When charger detect full charge, charger stop charging.
･ Charger should start charging at temperature range 0~40℃.
②Discharge
･ Discharge current must be below 5.0A/cell.
･ Discharge temperature range should be -20~60℃.
･ Discharge end voltage must be over 3.0V/cell.
③ Over-discharge
･ Do not over-discharge a battery below 2.0V/cell.
④ Battery position in Note PC and charger.
･ To avoid degradation of battery performance by heat, a battery should set the place
apart from heat generating electronic parts inside Note PC and charger.
8-2. Precautions on Battery Pack Design.
① Battery pack Shape, Mechanism and Material
･ Do not make the shape which easy connect to other chargers exclusive of charger.
･ Do not make the shape and mechanism which easy use another equipment exclusive of
Note PC and charger.
･ Do not make the terminal shape which easy cause short circuit by metal object such as
necklaces, hairpins, etc. And further, have over current protection function to prevent
outer short circuit.
･ Do not make the terminal shape and mechanism which connect reverse to equipment.
･ Do not make the shape and mechanism which static electricity and water easy go
through the battery pack inside.
･ Make the shape and mechanism which can inspect protection circuit function (specified
paragraph 8-2②) before the battery pack makes completely.
