hybrids in current use employ a parallel system known as integrated motor assist system.

(IMA). The power split has additional advantages but is also more complex.

The IMA method is a technologically advanced parallel hybrid power system. By using techniques such as brake-energy regeneration to maximize the effi ciency with which energy is used, it combines low-pollution, low-cost operation with high levels of safety and running performance. The main components of the system are:

● IMA motor

● battery module

● power drive unit (PDU)

● motor control module (MCM)

● d.c. – d.c. converter.

There are fi ve main IMA operating modes. Figures 2.347 and 2.348 give an overview of each mode and Table 2.4 explains these modes in more detail.
