Ima Hybrid Ystem - Honda Insight Owner's Manual

YBRID YSTEM
A hybrid power system for an automobile can have a series configuration or a parallel configuration.
With a series system, an engine drives a generator, which in turn powers a motor, whose output propels the
vehicle. With a parallel system, the engine and motor can both be used to propel the vehicle. The Insight
employs a parallel system that is described by Honda as the Integrated Motor Assist (IMA) system.
The IMA system is one of the most technologically advanced parallel hybrid power systems in the
world. By employing techniques such as brake-energy regeneration to maximize the efficiency with which
energy is used, it combines low-pollution, low-cost operation with high levels of safety and running
performance.
The main parts of the Insight's IMA system are:
•
Gasoline Engine
•
Motor / generator
•
Battery Module (High-voltage battery)
•
Battery Condition Monitor (BCM)
•
12v battery
•
Motor Drive Module (MDM)
•
DC-DC converter
•
Motor Control Module
A thin design motor/generator is located between the 3-cylinder engine and the 5 speed manual
transmission. A Ni-MH battery module is used for supplying electricity to the motor during assist mode and
for storing regenerated power.
A DC-DC converter is used to produce 12v power required by the Insight's 12v system. All high
voltage components of the IMA system are collectively located behind the seats in the IPU (Intelligent
Power Unit) box.
