Week 2 Session 7

Series Architecture

• Here motor is only element that is directly connected to the transmission system
• There is no direct connection of ICE engine with transmission system
• Here there is generator along with the ICE engine for producing electric energy from ICE engine.
• Motor get electrical energy either from battery or ICE engine
• Less travel range
• Engine smaller

Advantages-

• Only motor is connected to transmission system so no need of multi ratio gear box.
• Here engine operates at its maximum efficiency points.

disadvantages-

• Energy efficiency is less
• Extra generator is required so more space is accomodated
• more costlier

Parallel Architecture

• Here motor and ICE engine is directly connected to the transmission system
• No generator along with ICE engine
• Motor get electrical energy from battery only
• More travel range
• Engine is not smaller

Advantages-

• Less costlier as compared to series and series-parallel
• Energy efficiency is high as compared to series
• less space is accomodated

disadvantages-

• Multi ratio gear box may require
• efficiency is low at low rotation speed
• ICE engine cannot be used to charge the battery

Series-Parallel Architecture

• Here there is power split module
• Series path from engine to wheel
• parallel path from battery to wheel through power split
• Generator is present along with engine

Advantages-

• more efficient

disadvantages-

• it is complex
• more space is accomodated
• costlier
