Power electronic and battery analysis of Vectrix Scooter


In 2010, a presentation was done in PCIM [1] about the performance improvements of a small electric car with the replacement of the initial NiCd battery by an iron phosphate Lithium ion battery (LiFePO4). The small car is an AX, an old French electric vehicle from Citroën with a separate excitation DC electric motor. This car has been chosen to illustrate a light electric car around 850 kg with the good level of security provided by LiFePO4 and with a 20 minutes fast charge. The other demonstrator vehicle in the laboratory is a Vectrix scooter, which is an illustration of good power electronic and electric motorization state of art in a modern vehicle. The goal of this presentation is to detailed the scooter power electronic and motor, to compare NimH battery specifications and test results, to present some reliability aspects after one year of use, and the interest of iron phosphate batteries in replacement of NimH ones in this application
