How Electric Cars Work

How E ectric Work CARS Electric vehicle (EV) sales have FAST FACTS doubled each year over the past 3 years & could reach 1 million globally by 2016 Environmental benefits |include reduced oil dependency, air pollution & noise Range varies from 50-200 KM, sufficient for most daily urban commuting Range-extended EVs (Chevrolet Volt) has a battery pack plus a gasoline "range extender" engine that can generate more electricity if necessary Battery-only EVs (Nissan Leaf or Teslas) are propelled purely by a battery pack 4 ELECTRIC VEHICLE TYPES Hybrid EVs (Toyota Prius) have an electric motor backed by internal combustion engine, which turns on whenever maximum power is required Pumps electricity into rechargeable battery pack, monitoring voltage, current flow & temperature to minimize charging time CHARGING SYSTEM E Batteries can be charged overnight from normal electric outlets in 4 hrs with a 220V plug or from half-full as fast as 20 min at a roadside station Instead of an internal combustion engine, electric cars like Tesla use a bank of thousands of lithium-ion batteries, like those in your laptop Battery's power defines the range, acceleration ability & recharge time BATTERY (ENERGY STORAGE SYSTEM) Converts electrical energy from the battery to mechanical energy (to turn the wheels) & also converts mechanical energy back into electrical energy to charge the battery (through regenerative braking) MOTOR/ & GENERATOR Electric motors can propel the rear wheels, the front wheels, or independently turn each wheel With less energy creating frictional heat in the brakes, there is less wear on brake pads & other components REGENERATIVE BRAKING E=me Efficiently captures kinetic energy from forward motion usually lost when braking & automatically transfers it back to storage battery, converted into electricity Governs the vehicle's operation by continuously receiving input from CONTROL UNIT O the driver while monitoring several feedback signals via a complex microprocessor Controls the amount of current flowing from the battery bank to the motor based on input from accelerator pedal - plus voltage levels, temperature, motor's RPM, torque & more Automotive Technicians & Mechanics require require specialized training to service increasingly sophisticated electric technology. in 8* 1-888-546-2886 Automotive TRAINING CENTRES 604-635-2222
