With the increasing awareness of global warming around
the world, the demand for clean fuel/energy is on the rise
and as a result there is a continuous shift towards the
electric vehicles (EVs) and hybrid electric vehicles (HEVs).
Battery forms one of the most critical systems in any
electric vehicle. Battery performance is influenced by
factors such as depth of discharge (DOD), temperature and
charging algorithm. EVs and HEVs use battery
management system (BMS) to address the implementation
of monitoring system parameters such as current, voltage
and temperature. This paper attempts to provide a
measurement of electrolyte temperature, electrolyte level
and no. of backup hours parameters of lead-acid batteries
