Developing a monitoring system for Toyota Prius battery-packs for longer term performance issues [PDF]

open access: yes, 2013
The Toyota Prius battery pack consists of 38 individual battery blades, each blade contains 6 NiMH cells in series. This means that each pack contains 228 NiMH cells. Given this number of individually manufactured cells combined into a large battery pack,

A Novel Cyclic Time to Digital Converter Based on Triple-Slope Interpolation and Time Amplification [PDF]

open access: yes, 2015
This paper investigates a novel cyclic time-to-digital converter (TDC) which employs triple-slope analog interpolation and time amplification techniques for digitizing the time interval between the rising edges of two input signals(Start and Stop).

Design and Development of Low Torque Ripple Variable-Speed Drive System With Six-Phase Switched Reluctance Motors [PDF]

open access: yes, 2018
Switched reluctance motor (SRM) drives conventionally use current control techniques at low speed and voltage control techniques at high speed. However, these conventional methods usually fail to restrain the torque ripple, which is normally associated ...

Failure analysis of some Toyota Prius battery packs and potential for recovery [PDF]

open access: yes, 2011
The Toyota Prius battery pack consists of 38 individual battery blades, each blade contains 6 NiMH cells in series. This means that each pack contains 228 NiMH cells. Each cell has the potential to fail.
