TCS Interview Questions and Answers

We use different types of batteries depending on the vehicle type and model.

• Electric vehicles use lithium-ion batteries

• Hybrid vehicles use nickel-metal hydride batteries

• Conventional vehicles use lead-acid batteries

• Some high-end vehicles use advanced lead-acid or lithium-ion batteries

• Battery specifications may vary depending on the manufacturer and model

BMS manages battery charging by monitoring voltage, current, and temperature.

• BMS ensures that the battery is charged within safe limits to prevent damage.

• It monitors the voltage, current, and temperature of the battery to determine the charging rate.

• BMS may also control the charging process by adjusting the charging rate based on the battery's state of charge.

• For example, if the battery is nearly full, the BMS may reduce the charging rate to prevent overcharging.

• BMS may also ...read more

Electric vehicles are vehicles that run on electric motors powered by rechargeable batteries instead of internal combustion engines.

• Electric vehicles are environmentally friendly as they emit no tailpipe pollutants

• They are more energy-efficient than traditional vehicles

• Examples of electric vehicles include Tesla Model S, Nissan Leaf, and Chevrolet Bolt

• Electric vehicles require charging stations for recharging their batteries

• The range of electric vehicles is improving with adv...read more

Electric vehicles run on electricity stored in batteries that power an electric motor.

• Electricity is stored in batteries

• Electric motor converts electrical energy into mechanical energy

• No need for gasoline or diesel fuel

• Regenerative braking system helps recharge the battery while driving

• Range varies depending on battery capacity and driving conditions

Electric motors are commonly used in buses for propulsion.

• Electric motors are commonly used in buses for propulsion

• Types of drive motors used in buses include AC induction motors, permanent magnet motors, and switched reluctance motors

• Electric buses may also use battery electric propulsion systems or fuel cell electric propulsion systems

Regeneration of power refers to the process of restoring energy to a power source.

• Regeneration can occur in various forms of energy, such as mechanical, electrical, and thermal.

• Examples of regeneration include regenerative braking in hybrid cars and regenerative heat exchangers in power plants.

• Regeneration is an important aspect of energy efficiency and sustainability.

• It can also help reduce costs and improve overall system performance.
