a V6 power plant using nickel-metal hydride (NiMH) battery technology and a
system voltage of 550 V.
The HSD represents TMC's third generation of hybrid technology after their
Toyota Hybrid System THS 1 and 2, plus the THS-C for continuously variable
transmission (CVT) architecture. The previous generation THS-C on display at
the 2002 Electric Vehicle Symposium is shown in Figure 1.2 and consists of a small
4-cylinder ICE and twin electric motors integrated into the transmission. The
NiMH battery pack is to the right in the picture.

The orange coloured (bundle of 3 cables and bundle of 2 cables) high voltage
distribution and motor harness wire shown in Figure 1.2 are consistent with
industry cable identification and markings. A power electronic centre is mounted
above the transmission. The power electronic centre receives dc power from
the battery pack via the two cables and processes this into ac power for both
