Title
Specifications of Lithium Ion battery (Prismatic Type)
･ Fix cells with mold case by rib, tape, glue etc., but do not make damage cells (especially
sealing part) by rib or sharp part of mold case.
In case of the battery pack is struck by hard shock or vibration, the battery pack has
possibility to cause leakage, smoke, explosion.
･ Do not apply heat, pressure, shock or any other damages against gas release vent area.
SANYO does not take any responsibility for degradation of cell performance or troubles
caused by the external factors.
･ Weld mold case by glue. Not weld mold case by ultra sonic welding. If the ultra sonic is
used for welding of mold cases, SANYO will not accept any responsibility for any defects.
･ Make the structure where the end user cannot remove the pack easily.
② Protection Circuit
Have protection circuit function which is described below inside battery pack, to insure
safety of battery in case of misuse.
Overcharge protection
･
The overcharge protection should work when the cell voltage or the voltage of cell block
will be over 4.25V.
However, in case that the charge system can control the cell voltage or the voltage of
cell block within 4.25V, the overcharge protection can be controlled near 4.25V.
Over discharge protection
･
At the voltage range 2.20~2.40V/cell, over discharge protection should work.
Then discharge current shall be shut down and consumption current is below 1µA.
Over discharge Current Protection
･
When discharge current exceed about 3.76A, over discharge current protection should
work. Then over discharge current shall be shut down.
③ Electric circuit
･ To avoid to discharge during storage, design the low consumption current electronic
circuit(e.g. Protection circuit, fuel gauge, etc) inside battery pack.
④ Battery connection
･ Do not solder onto a cell in order to avoid a damage on the cell.
Weld spot welding lead plate onto cell, and solder lead wire or lead plate.
⑤ Precautions on label
･ Write information and precautions on label. Precautions are based on chapter 14.
Write the precaution manual based on chapter 14.
