Hybrids Types of Hybrids Powertrain Configurations

  1. 1. Hybrids Types of Hybrids Powertrain Configurations Hybrid terms
  2. 2. Hybrid Types <ul><li>Full Hybrid </li></ul><ul><ul><li>Can be driven for short distances by electric motor alone </li></ul></ul><ul><ul><li>ICE (internal combustion engine) turns on when battery charge drops below a certain threshold or on heavy accele ration </li></ul></ul><ul><ul><li>Both engine and motor work together to provide propulsion for vehicle </li></ul></ul><ul><ul><ul><li>Examples: Toyota Prius; Ford Fusion; Chevy Tahoe </li></ul></ul></ul>
  3. 3. Hybrid Types <ul><li>Mild Hybrid </li></ul><ul><ul><li>Uses electric motor to supplement ICE </li></ul></ul><ul><ul><li>Electric motor is mounted between ICE and transmission </li></ul></ul><ul><ul><li>Efficiency is gained from use of small engine and stop/start system </li></ul></ul><ul><ul><ul><li>Examples: Honda Civic </li></ul></ul></ul>
  4. 4. Powertrain Configurations <ul><li>Parallel Hybrid </li></ul><ul><ul><li>Uses both ICE and electric motor for vehicle propulsion together </li></ul></ul><ul><ul><li>Electric motor can be switched as a generator to recharge battery pack during deceleration </li></ul></ul><ul><ul><li>ICE is used as main power source and electric motor as assistance </li></ul></ul><ul><ul><ul><li>Example: Honda Civic, Insight </li></ul></ul></ul>
  5. 5. Powertrain Configurations <ul><li>Series Hybrid </li></ul><ul><ul><li>ICE drives a generator to power electric motor and recharge battery pack </li></ul></ul><ul><ul><li>Electric motor drives vehicle from electricity produced by generator </li></ul></ul><ul><ul><li>Efficiencies gained by operating small ICE in a narrow operating range for generator operation </li></ul></ul><ul><ul><ul><li>Example: Chevy Volt </li></ul></ul></ul>
  6. 6. Powertrain Configurations <ul><li>Series-Parallel Hybrid </li></ul><ul><ul><li>Combines systems with two electric motors and one ICE </li></ul></ul><ul><ul><li>Propulsion power can come from one electric motor or electric motor and ICE </li></ul></ul><ul><ul><li>ICE excess power can be used to generate electricity while driving vehicle </li></ul></ul><ul><ul><ul><li>Example: Toyota Prius; Ford Escape; Chevy Tahoe </li></ul></ul></ul>
  7. 8. Hybrid Terms <ul><li>Belt-Alternator Starter system (BAS) : combination of motor/generator bolted to front of engine and connects to engine with a belt </li></ul><ul><ul><li>Provides slight boost for acceleration </li></ul></ul><ul><ul><li>Generates electricity on deceleration </li></ul></ul><ul><ul><li>Allows stop/start operation of ICE </li></ul></ul><ul><ul><ul><li>Example: Saturn Vue </li></ul></ul></ul>
  8. 9. Hybrid Terms <ul><li>Plug-In Hybrid </li></ul><ul><ul><li>Initial charge is provided from electric grid </li></ul></ul><ul><ul><li>Propulsion comes entirely from electric motor(s) </li></ul></ul><ul><ul><li>Onboard ICE generates electricity for motor(s) and battery pack only </li></ul></ul><ul><ul><li>Range on initial charge is limited to about 40 miles </li></ul></ul><ul><ul><ul><li>Example: Chevy Volt (2010) </li></ul></ul></ul>
  9. 10. Hybrid Terms <ul><li>Two-Mode: marketing name for system using two electric motors/generators and an ICE </li></ul><ul><ul><li>At low speeds vehicle can use electric motors or ICE or any combination for propulsion </li></ul></ul><ul><ul><li>At high speeds or with heavy loads, ICE is used constantly and can use assistance from electric motors </li></ul></ul><ul><ul><ul><li>Example: Chevy Tahoe </li></ul></ul></ul>
