The first ever automotive was an electric car. not an Internal Combustion Engine. 1832 by Robert Anderson. Then the first gasoline car was made by 1886 Karl Benz
Tesla uses BYD’s Blade Battery in Model Y in Giga Berlin
Current oil reserves are expected to run out by 2052
Battery Management System - Thermal Engineering - controlling the battery temperature
standardising battery manufacturing in EU for battery swapping
Israel working on a technology that doesn’t require battery
direct injection - is the reason for not having kicker in the bikes in Bajaj
9 - 11 V are required for ignition, however, kicker only produces 5-7 voltage, so it’s of no use in the new vehicles
12 V - is used for the bike batteries
phase current - single phase and triple phase current.
why are we not using more phases like 4,5,6,7..
what is the difference between generator and alternator
radiator cools the ICE engine for keeping the engine at the same temperature (maintain temperature)
glycol based material used for coolant
AC current is more dangerous than DC current for a human
Important Factors 2. Fuel 3. Power Train 4. Weight 5. selection of vehicles, VSI, VDI, VXI 6. price and incentives 7. vehicle range 8. fuel economy 9. maintenance 10. pollution 11. noise 12. battery replacement 13. refill / recharge
four converters
- AC → DC (mobile phone adapters)
- DC → DC (from one battery to another battery)
- DC → AC (inverter, )
- AC → AC (fans, lights, voltage step-down transformer)
Daytime Running Light (DRL) -
3 phases of the current in a single line - its called a panthograph if there were three lines, it would result in a lot of sparks
trains use 25,000 V for trains
tambaram station can’t run all the trains (5 trains) at the same time, so a diesel engine comes in to tug and pull the train out of the station if this happens
flywheels, make the wheels move in a continuous speed. The train wheels converters like (AC → DC → AC) to the wheels
Regenerative breaking
PMSM - permanent magnet syncrhonous motor , especially 4 wheelers
choke for older vehicles to give air flow to the engine using a secondary airflow pipe, to make sure that the fuel to air mix ratio is good for achieving highest amount of combustion
throttle cables for two wheelers was stopped
drive, break by wire ADA, Lane Departure
RC390 - throttle pedal - based on resistance of the pedals, varying input instead of a step function based input
