The electric power requirement
of the two motors is fulfilled by
600 Lithium Ferrous Phosphate
cells each of 3.3V. Due to the
higher chemical stability of these
cells, they are able to power the
vehicle for a longer time, more
reliably. The 600 batteries are in
12 packs, with 50 batteries in each
pack. With the high performance
of the vehicle, batteries generate
heat which could reduce the efficiency
of the vehicle. As a solution,
the Vega team has implemented
a glycol cooling system
to reduce the temperature of the
batteries.
As the car drives on, the voltage
of the cells gradually reduces. If
a cell drops below a certain level
of voltage, it would be destroyed.
Therefore, a digital battery monitoring
system is also implemented
in the Vega supercar. This
system specifically identifies the
usage of all 600 cells of the car
and alerts the user if any of the
batteries have reached the critical
level, so that it can be recharged or replaced, accordingly.
Vega has an on-board charger. It can be fully recharged
using a domestic power supply in less than 4 hours. In addition,
the Vega team has also designed a public charging
station. The team also plans to implement a supercharging
unit, in such a way that 80% of the battery will be
charged within 20 minutes. This would result in just less
than 30 minutes of charging to drive up to 250km! Isn’t
that amazing?
