Battery cell test, improve security
Post via Apple battery which contained by laptop battery IN us.
Battery cell test is usually done in the production process. In order to improve security, the guide recommends adding a new test, the test object using rechargeable battery good power core. Test, deliberately inserted between the electrode a metal particle, and then pressed to produce A1175 or apple A1175 such a short circuit. Can be observed by testing the internal short-circuit power core state.
In notebook computers, lithium-ion ibook g4 12 battery is not a single use, but rather a number of battery-core build-up in a package. Usually two battery cells in parallel with the formation of lumps, and then thread a few blocks further. This is also the guide of battery packaging design requirements.
Guidelines described in detail in a number of aspects of the method to avoid thermal runaway, for example, block layout, based on each block (not per package) the precise charge voltage control, and control circuit board and powerbook g4 battery cores isolation.
JEITA and BAJ have raised the hope that in Japan, IEC Sub-Committee to develop guidelines for their submission to the IECSA-21 and IECTC-108 Committee with battery blog here.
