Electric Vehicle Introduction

  1. 1. Electric Vehicles (EV/HEV/PHEV) Prepared by : Weiso Chen Date : 7/9/2010
  2. 2. What? <ul><li>PHEV: Plug-In Hybrid Electric Vehicle </li></ul><ul><li>HEV: Hybrid EV, the vehicle with two or more power supplies, one of those is electrical energy </li></ul>
  3. 3. What Needed? <ul><li>Battery Pack </li></ul><ul><li>Charger </li></ul><ul><li>Inverter </li></ul><ul><li>Power Grid Infrastructure </li></ul><ul><li>DC/DC </li></ul>Source: http://www.ti.com/hev
  4. 4. Architecture Source: http://www.ti.com/hev
  5. 5. Series vs Parallel <ul><li>Series Configuration: permits mechanical decouple. This allows a greater freedom in the physical layout of subsystems that makes system packaging easier. </li></ul><ul><li>Parallel Configuration: has over Series is one of higher energy efficiency. </li></ul>Source: http://www.engineering.sdsu.edu/~hev
  6. 6. EV Structure BMW MINI E Construction
  7. 7. Motor Drivers-DC vs AC <ul><li>Requirements: Hi performance, Low Cost, Hi Power density, Low speed, Hi Torque, Wide Range Variable Speed, Strong Overload Capability, Reliability, etc. </li></ul><ul><li>DC Motors were common in variable speed applications. </li></ul><ul><li>AC Motors and Controllers have allowed for variable speed, a viable candidate for electrically driven vehicles. AC (asynchronous induction motor), Low Cost, Higher Efficiency in long range operation. </li></ul>Source: Design for Motor Controller in HEV based on Vector Frequency Conversion Technology, Jian Lian, et al. 2009
  8. 8. Motor-Example <ul><li>ACP AC-150 (to be used on Luxgen EV?) </li></ul><ul><li>The system delivers up to 150 kW (200hp) motor output, yet maximizes vehicle operating range with high efficiency over a broad operating range and comprehensive energy recovery through regenerative braking. </li></ul><ul><li>Characteristics: </li></ul><ul><li>Output 200hp @ 6000-12000 rpm (at motor shaft165ft-lb @ 0-5000 rpm) </li></ul><ul><li>Efficiency 91% peak efficiency (Battery to shaft 86% at road load) </li></ul><ul><li>Charger 200 to 20,000 watt (Unity PF, GFI compatible Reductive) </li></ul><ul><li>Package 180 lb. Total weight including cooling system </li></ul><ul><li>Operating: </li></ul><ul><li>Voltage 336V nominal 240V min, 420 V max </li></ul><ul><li>Current 520A max (drive) 200A max (regeneration) </li></ul><ul><li>Torque 165 ft-lb. max, 0-5000 rpm (drive) 85 ft-lb. max (regeneration) </li></ul><ul><li>Power 200 hp max 6000-12000 rpm 70 hp continuous </li></ul><ul><li>Efficiency 91% peak (40 hp, 8500 rpm) 86% road load (10 hp, 8500 rpm) >90% recharge (240V line, 10 kW) </li></ul>
