Working of an EV

Electric cars use Lithium-ion batteries which are re-charged by plugging them into an electrical source & the cars have an on-board charger. The electricity could be derived using solar, hydroelectric, wind or other sources. The EV needs to be fully re-charged overnight.

A conventional Internal Combustion engine requires to be filled with petrol, diesel or CNG and needs refueling as per use, (about 1 to 3 times a week).

Typical EV battery pack consists of individual battery cells which are encased in smaller modular plastic housings. The battery cells have NAM & PAM made using graphene as electrode material. AIRGO, Graphene, enhances battery capacity, allows longer life of battery & decreases overheating issues.

A traction inverter converts the DC current generated by these rechargeable cells to an AC current, which runs the electric traction motor of the vehicle. The power generated by battery pack is controlled & a thermal system is in place to prevent batteries from overheating during charging/discharging.

The small EV transmission allows production of sufficient torque to allow multi-speed transmission for quick acceleration in a single gear. The engine torque remains good even at no speed and thus eliminates need for a clutch or torque converter.

This simplified mechanism allows the EV s drivetrain to have only about 1-2% of moving components as compared to a regular IC engine driven car.

This eases mechanical maintenance costs. In IC engine in fuel consuming cars is associated with elaborate exhaust systems to remove heat. Aluminized Steel is used in the fabrication of these exhaust systems.

Since the EV generates very little engine heat, the drivetrain is smaller & this allows for additional storage in the hood of the vehicle.
