Light Electric Vehicles - 越創科技 VIETTRON

Light Electric Vehicles

Based upon being a solution provider of light electric vehicles and applications, Viettron's business deliverable is comprehensive to fulfill the requirements of a customer. We specialize in designing core electrification components, such as battery management system, motor, power control unit, and vehicle control unit, and systemizing them for the targeted electric vehicles. System Integration encompasses customization with which we make alterations or modifications on our modules linking together hardware and software applications physically and functionally to act as a coordinated whole. Besides phase 1 and phase 2 where our services focus on bringing together component subsystems into the vehicles or machinery, we offer optimization services of modernizing different forms of software integration to upgrade existing systems and equipment, also implementing new verification solutions before production and manufacturing. Our services ultimately aim to increase the value for a customer who joins us to participate in more green energy production for our environment.

PRODUCTS

While collaborating with Viettron, you will be offered total solutions for your electric automotive applications under 50kW. We possess profound expertise in vehicle categories of off-road vehicles, powersports cargo, and particular duty vehicles, by not only providing you core components but also bringing together parts and systems. What follows is a list of a wide range of our available products and services.

PCU

The Power Control Unit (PCU) developed by Viettron is a bridge between the electric energy storage unit and the power output unit. It provides robust high-power output capability for controlling the bidirectional flow of electric energy between those two units. Viettron customizes power control modes and designs hardware circuits and software algorithm, such as torque control, speed control, speed limit control, and constant speed control. With its advanced embedded programmable controller OS, motor drive algorithms, and modular hardware architecture, the motor driver achieves unprecedented flexibility in application, motor control, and powerful expandability.

HUB-MOTOR

Redefing urban mobility with Viettron’s Hub-Motor series and integrating the power source directly into the wheel, we’ve created a compact, space-saving solution that eliminates the need for traditional drivetrains.

Features: 1. Space-Saving Solution 2. Simplified Drive Architecture 3. Near-Silent Operation 4. Zero Maintenance Drivetrain 5. Instant Torque Response

VCU

Vehicle Control Unit (VCU) developed by Viettron is an embedded system as an electrical control solution for modern vehicles. Our VCU is based on the ARM architecture, ASIL-B level, and the processor with a processing speed is up to 112MHz, making it ideal for the development of two-wheel electric vehicles with a complete functioning performance and an input and output control management interface. Our VCU also automatically performs analyses of the system or components. It controls functions that include power control and management, general I/O control, switch detection, car lights, horn, water pump, grip-lock during run time, peripheral control, battery charge and discharge management, sound management, Bluetooth (i.e., keyless) and peripheral communication interface CAN BUS 2.0B, and vehicle-mounted 3-axis inertial measurement element.

[Keyless] A remote keyless is an extended technology of VCU that is specifically through the Bluetooth module supporting the keyless entry to allow you to remotely power on/off your vehicles without physical contact.

SERVICES

FOUR-ELECTRIC NETWORK

In addition to product and module solutions, our alternative service about forming a LEV ecosystem means to bring together vehicle control unit, powertrain, battery energy management, and charging systems with power storage and PMS. Our endeavors are to maximize our solutions for the core compartments of an electric vehicle conforming segments to perform effectively.

I. Battery Energy Management:

includes battery cell and pack selections as well as battery management system that we assist you in configuring the delivery of targeted range of voltage and current for a duration of time for your electric vehicle.

II. Power Control Unit (PCU):

manages the power conversion and the motor. Our PCU, both liquid and air cooling, is compatible with motors with voltage at 72V/300A, 96V/400A, and 144V/250A.

III. Motor:

converts electrical energy into mechanical energy. We offer the motor selection range from 1K to 30kW (maximum power)

IV. Vehicle Control Unit (VCU):

plays the central role of controlling vehicle functions and powertrain, as the vehicle central management entity in charging of any segment of a vehicle to function expectedly.

V. On Board Charger (OBC):

generates electricity through On Board Charger (OBC). Our OBC meets the European standard IEC62196 Type 2 Level 1. The input power range is 220VAC/32A, and the power range is 90 to 264VAC/47 to 63Hz. The conversion efficiency is EFF>90%. This OBC can also be connected to a household power source with an external charging adapter for use at home.

IoT Service

I. Cloud Platform:

collects, tracks, and analyzes vehicle information including its location, performance, mechanical data, etc. The data is used to monitor the status of vehicles and conduct data analyses for further automotive invention.

II. Four-Electric Network:
