To develop ultra-capacitor for cranking engine in extreme cold conditions (-500 C).
Description
- With respect to sustenance of ‘A’ vehicles in High Altitude Areas (HAA), it is found that under extreme cold climatic conditions, the battery of Armoured Fighting Vehicle (AFV) does not hold charge and do not perform optimally. During extreme cold climate conditions of Eastern Ladakh, Pre Heater assembly generally takes 20-30 minutes to pre heat the engine. Due to this prolonged duration, it puts heavy strain on batteries, in majority instances batteries are not capable to withstand for this duration.
- Ultra capacitors are primarily intended for backing up electronic system during Voltage dips of duration. While starting of engine in harsh weather conditions (under sub-zero temperature), Ultra Capacitors can provide desirable/ optimum solution.
- The 24V storage batteries are connected parallelly in the tank in AFV, the 12V storage lead acid batteries are connected in series and parallel in pairs. During starting the engine by the starter, the storage batteries are changeover to voltage of 48V by starter generator relay. To develop robust Ultra Capacitor to be fitted inside the tank to charge the above batteries without effecting the functioning and positioning of existing system fitted in the tank.
