The memory effect only vanished if one waited a sufficiently long time after a cycle of partial charging followed by full discharge. In such cases, the two particle groups were still separated ...

Here we report a memory effect in LiFePO 4 —one of the materials used for the positive electrode in Li-ion batteries—that appears already after only one cycle of partial charge and discharge.

Partial discharge testing is a useful technique for assessing the condition of individual electrical assets, but it is of far greater value when applied to groups of equipment... Newsletter ...

Transient earth voltage sensors make use of the skin effect to measure electromagnetic radiation due to internal partial discharge. This is an attractive sensing option because measurements are ...

Called FLIR Si124, it offers built-in analytics for automatic recognition of partial discharge in high-voltage electrical ... algorithms automatically detecting and analysing electric-discharge ...

Partial discharge (PD) measurement has been used for several decades to assess the condition of high voltage (HV) and medium voltage (MV) electrical apparatus. In the past, the application was mostly ...

That means deep-discharge cycles are not required. In fact, it’s better for the battery to use partial-discharge cycles. There is one exception. Battery experts suggest that after 30 charges ...
