“ELECTRIC HYBRID VEHICLE(TESLA CAR)” SEMINAR By Mr. JADHAV VISHAL S. Roll No-41 Div-A Under the guidance of Prof. Ghodke.A.P. [1]

A Seminar on “ELECTRIC MOTOR VEHICLE(TESLA CAR)” By Mr. Jadhav Vishal S. Guide Prof. Ghodke.A.P. Department of Mechanical Engineering S.N.D. COLLEGE OF ENGINEERING & RESEARCH CENTER, YEOLA (NASIK)

I NTRODUCTION [3]  Electric cars are automobiles, which are powered by the electric engine and electric energy.  The development of the electric vehicles is a very perspective and important process.  EVs, are vehicles that are powered by an electric motor instead of an internal combustion engine.

H ISTORYOFTHE E LECTRIC V EHICLE [4]     The history of the electric vehicle began in the mid- 19th century. 1832:RobertAndersoninventsanon-rechargeable electric carriage. 1835:ThomasDavenportbuildsthefirstpractical electric vehicle. 1976: General Electric was chosen to construct a parallel-hybrid sedan, and Toyota built its first hybrid car.

C OMPONENTS  Motor  Controller  Charger  DC/DC Converter  Contactors  Batteries [5]

M OTOR  Generally the Brushless DC Motor is used. Simpler to maintain, More durable, Smaller. 85%–90% more efficient. Able to self-start. [6]

C ONTROLLER  Control the BLDC motor. Increase efficiency, reliability and extended battery life time. [7]

 C HARGER I T CONTAINS A PLUG THAT CONNECTS ELECTRIC VEHICLE BATTERIES TO AN ELECTRICAL SOURCE, PROVIDING THE BATTERIES WITH ELECTRICAL ENERGY. [8]

DC/DC C ONVERTER  Recharges thebattery through DC converter. The Iota DLS-55 is the most common option. [9]

C ONTACTORS   This is like a big ON switch, powering up the drive circuit when we turn the key. The Nanfeng ZJW400A is an economical option, or the Gigavac GX14 is a higher powered option. [1010]

Complexity is hidden behind an elegant and functional design.  Totally Touchscreen Display 1: Technology and Products “Aim to provide the best products for customers”  Simple and reliable powertrain  lowest drag coefficient

1: Technology and Products “Aim to provide the best products for customers”  Leading battery and charging technology  Highest NHTSA safety rating Top speed to 250 km/h and accelerate from 0 to100 km/h within 3.3-second, While the normal speed is below 100 km/h.  The fastest 4-door sedan in history  The longest range The maximum range is 426 km with 85 kWh, while others can only achieve 150 km. Super charge : Finish 80% charging within 30 minutes

B ATTERIES FOR THE EV [13] carsarecarsare  Thebatteriesthatareusedforelectric Rechargeable batteries used in electric vehicles include lead –acid batteries.

P OWER FROMTHE E LECTRIC M OTOR [15]  Anelectricmotorhaspowerandinturnputsouta force that is measured in torque.

C ONTD … [16]  The basic equation for power is: P = Tw(1)  For a basic motor there are two parameters that can help show how the motor works.  Velocity function: P (w) = - (T s / w n ) w 2 + T s w(2)  Torque function: P (w) = - (w n / T s ) T 2 + w n T(3)

C ONTD …  T HE ELECTRIC MOTOR CONTROLLER TAKES THE POWER FROM THE BATTERIES AND DELIVERS IT TO THE MOTOR. [17]

C ONTD …  W ORKING OF ELECTRIC ENGINE AND BLDC MOTOR. [18]

V ARIOUS EV [19]

A DVANTAGES [20]  Reducedependencesonoiland gasoline.  Pollutants and noise free.  Recyclable batteries.  No fire hazards.  Lowmaintenanceandoperation cost.

D ISADVANTAGES [21]  High price,Tesla modal costs around $50,000.  High recharge time.  Silence may be fatal.  Range lies between miles only.

C ONCLUSION [22]  With this, we come to following facts that number of expected vehicles doubling on the roads in the near future the need for this alternative energy is very evident and has promising returns.  Important to produce vehicles that do less, have a longer range, and use less energy.  Lower our toxic emissions and localize green house effects.  Increase the overall energy efficiency of cars.

Conclusion what can we learn from Tesla ? (1) Start with a great product, and make it better ! (2) Break the traditional constrains and redefine the products ! (3) Accurate products positioning and target customer searching ! (4) Focus on the customer experiences
