LS 600h L Hybrid Technology (continued)
Inverter – Converts the hybrid battery’s high voltage DC current into
AC current for the electric motors and vice versa, depending on driving
demands and electrical system needs. The inverter can also boost the
hybrid battery’s power up to 650 volts as needed.
Hybrid Electronic ControlSystem - Monitors and controls the power
flow operation of MG1, MG2 and the inverter.
RegenerativeBraking System – Helps recover energy used to slow the
vehicle during braking or coasting. During braking or coasting, MG2
turns into a generator, which creates electricity to help charge the hybrid
battery. As MG2 creates electricity, it creates drag, which helps slow the
vehicle. The conventional brake system and the regenerative brake system
work in conjunction with each other.
Electronically-controlled Continuously Variable Transmission (ECVT) –
Delivers smooth acceleration without conventional gear shifting, while
enhancing efficiency. It has fewer parts than a conventional automatic
transmission. MG1 and MG2 are part of the ECVT. The advanced
combination of the electric motor/generators and low and high range
torque multiplication device helps optimize available performance
and economy.
12-volt Battery – Enables the Hybrid Electronic Control System to "start"
the vehicle (vehicle “READY” mode) and operates the basic
electrical system. This battery is charged by the DC/DC converter.
