What is the working principle of an electric vehicle?

Electric cars function by plugging into a charge point and taking electricity from the grid. They store the electricity in rechargeable batteries that power an electric motor, which turns the wheels. Electric cars accelerate faster than vehicles with traditional fuel engines – so they feel lighter to drive.

How do I choose a battery for my electric car?

To obtain the energy content of a battery, multiply the battery capacity in Ah by the voltage to obtain energy in Wh. For instance, a nickel-metal hydride battery with 1.2 V, and a lithium-ion battery with 3.2 V may have the same capacity, but the higher voltage of the lithium-ion would increase the energy.

What are the 3 types of batteries that have been used in electric cars?

There are four main kinds of batteries used in electric cars: lithium-ion, nickel-metal hydride, lead-acid, and ultracapacitors.

What size motor is in an electric car?

A typical motor will be in the 20,000-watt to 30,000-watt range. A typical controller will be in the 40,000-watt to 60,000-watt range (for example, a 96-volt controller will deliver a maximum of 400 or 600 amps).

How do you select a battery for a DC motor?

Capacity. A battery’s capacity determines roughly how long a battery will last at a specific voltage given a specific discharge rate. For example, if you choose a 12V, 2Ah (2000mAh) battery pack (regardless of chemistry), the battery should be able to run a 12V motor consuming 2A continuously for 1 hour.

Which battery is not suitable for electric vehicle?

The nickel-cadmium battery Used for the production of electric vehicles in the 90s, Ni-Cd batteries are now prohibited due to the toxicity of cadmium.

What are the different types of brushed DC motors?

There are four types of brushed DC motors. The first type, is the Permanent Magnet Brush DC Motor. Second, the shunt-wound brushed DC motor. Third is the series-wound DC motor and fourth is the compound-wound brushed DC motor which is a combination of both the shunt and series wound brushed DC motors.

Do brushed DC motors need a controller?

Brushed DC motors do not require a controller to switch current in the motor windings. Instead, it uses a mechanical commutation of the windings. A copper sleeve ( commutator ), resides on the axle of the rotor.

What type of motor is best for an electric car?

First of all, you can find many EV enthusiasts opting for series DC motors or three phase AC motors for their car conversion. DC motors are known for their higher torque and smooth handling of heavy loads.

What type of DC motor is used in low power control systems?

• Small dc motors used in low-power control systems are often the permanent -magnet type, wherein a constant field flux is established by a permanent magnet rather than by a current flowing in a field winding. • Three rotor positions of a typical low-power permanent-magnet dc motor are shown.
