Battery pack for large hybrid (HV) trucks

Functions On the hybrid vehicles that use engine and motor, the battery pack supplies power to the motor when starting and accelerating and recovers power from the motor when decelerating. Characteristics Production technology that achieves safe, reliable battery packs.

Control device

■ECU High reliability with installation on commercial vehicles in mind 12V/24V compatible.

Transfer controller ECU

Purpose: Protects mechanical structures such as transmissions, from improper operation by the driver Characteristics 2WD/4WD conversion, converts L0 gear/HI gear through electric control

AMT-ECU

Purpose: Automatically controls clutch operations and gear changes instead of the driver Characteristics Equipped with motor drive circuit to allow for directly controlling the electric actuator Optimum shifting of transmission speed helps improve fuel efficiency.

Vehicle Control ECU

Purpose: An integrated control ECU equipped with many input/output circuits and communication circuits. Characteristics Allows for adding/changing detailed specifications depending on the automobile manufacturers’ needs. (Can be generally used for vehicle control, data logging, communication gateway, EV control and more.)

HV-ECU

Purpose: Management control of the hybrid system so that cooperative control of engine and motor and battery conditions are optimally maintained. Characteristics Equipped with many communication circuits and input/output circuits. Allows for cooperative control with various devices.
■Relays High reliability with installation on commercial vehicles in mind Compatible with large current uses.

Switch Batteries

Purpose: Switches batteries and the electrical system between vehicles on and off. Characteristics

Starting replays

Purpose: Switches on and off the current by opening and closing the contact point to operate the starter. Characteristics Excellent cutoff ability and durability.

Safety Relay

Purpose: Detects engine rotation and protects the starter. Characteristics The starter protection feature is guaranteed to be activated even in low voltage condition when the engine is starting.

DC Motor

Functions Often installed together with a hydraulic pump and used as a hydraulic power unit. Used for a wide range of purposes, Characteristics * Diverse lineup depending on purposes Purpose: Operation of power tilt and trim, bilge pump, general hydraulic unit and cab tilting device. * Corrosion resistant (outboard engines): Improved corrosion resistance because of the design * Compact and lightweight (for installation on automobiles): Improved installation on automobiles and reduced costs Specification
