Is Lithium battery in and electric vehicle, particularly in the two wheelers a time bomb waiting to explore?

On one hand the max current drawn in electric two wheeler is quite low (generally less than 100 amp), the lithium batteries are not put to extreme stress, however most electric two wheeler batteries have no forced cooling therefore the chances of heat developed / heat trapped are higher.

A safe two wheeler battery system should have the following protection to call them 100% safe

  • Cell level fuse system
  • Smart BMS capable of sensing and triggering safety actions
  • Internal CNL battery fuse.
  • High current contactor kill switch
  • Motor controller safety shutdown
  • Voltage controller unit (VCU) safety discharge cutoff
  • Self extinguishing materials in construction.
