The industry’s leading EV manufacturing show
returns to the automotive capital of the world for its second annual outing.
Motives Moves On
TM4 will be at Electric & Hybrid
Vehicle Technology Expo to reveal its new and redesigned Motive family of
electric powertrains, which will comprise three motors and two inverters. Some
of the systems will be offered in low voltage (48V DC to 144V DC), a first for
TM4, which made it necessary for the company to design a brand-new type of
MOSFET-based inverter. In the low-voltage market, TM4 will be one of few
companies to offer fully optimized motor and controller sets.
Power-dense
electric powertrains designed specifically for automotive and light-duty
vehicle platforms.
The Motive series was already a market
leaders in terms of power density. By integrating new, innovative technologies,
it has been possible to boost torque ratings by 50% while maintaining weights
and dimensions.
Complete drive system
KLD Energy will present its oneDRIVE
electric drive system, which includes battery, motor and controller. This
technology substantially improves upon the performance, efficiency and value of
today’s electric motor systems by using revolutionary new motor and battery
designs, and intelligent motor controller software.
KLD’s oneDRIVE systems are the only
commercially available 48V direct drive products that can reach US highway and
European L7e quadricycle maximum speeds.
Its high-torque, low-RPM operation and
compact-design attributes make it ideally suited for direct-drive applications
– both in-wheel and configured inboard as an electric differential. Direct
drive completely eliminates the need for a chain, belt, sprockets, pulleys,
transmission, drive shaft and differential, along with the efficiency loss they
cause (which can reach over 20%), greatly improving reliability and eliminating
drive system maintenance.
Both systems can be configured for front or
rear drive, which can achieve an average of 250mpge; and four-wheel drive
operation, which can achieve 550mpge.
The
KLD oneDRIVE™ propulsion and generation system is composed of integrated
components that are specifically designed for each other and optimized for peak
performance and efficiency. Our system efficiency will provide up to 2x more
range than comparable systems.
Such impressive results are possible
because the system is an integrated drivetrain, not a pieced-together system
like those found elsewhere in the marketplace.
BMS Offerings
Free scale will use the Electric &
Hybrid Vehicle Technology Expo to showcase a growing product family – battery
management systems.
The company will be launching the
industry’s first general market AEC-Q100 qualified intelligent battery sensor
to combine three measurement channels, a 16/32bit MCU, and a CAN protocol
module, in a single package.
Designed to support both conventional and
emerging battery chemistries for automotive and industrial applications, the
MM9Z1J638 battery sensor measures key battery parameters for monitoring the
state of health, state of charge, and state of function for early-failure
prediction.
A flexible four-cell, front-end
architecture supports conventional 12V lead acid batteries as well as emerging
battery applications, such as 14V stacked cell Li-ion, high-voltage junction
boxes and 24V truck batteries.
A collection of advancement
At this year’s Electric & Hybrid
Vehicle Technology Expo, Kolektor Group will present two programs.
The first, Drive, consists of high performance
motor-generator KM-400/50 and electronic controller KMC-400/230 that can run in
motor or generator mode. Units are offered as a kit or separate part.
The KM-400/50 liquid-cooled motor is based
on robust radial flux brushless technology, with a continuous output power of
50kW at 7,000rpm, and it exhibits over 96% efficiency.
The KMC-400/230 electronic controller
supports the electric requirements of the motor-generator. It can operate in
the range of 50V DC to 420V DC, while delivering motor current up to 250Arms
per phase.
The
DC-CT products represent the latest, top-notch current sensing technology
available in DC CTthe market, offering wide bandwidth and ultimate performance.
The second program is Direct Current -
Current Transformer (DC-CT), whose measurement principle relies on a
zero-balance principle of a magnetic core, where two currents – a primary
measuring current, and a secondary compensating, sensing current – flow in
opposite directions, maintaining a zero-flux state in the core.
Inverter Ingenuity
John Deere Electronic Solutions has created
a family of inverters to provide advanced control for AC motor applications.
The product line covers a wide range of power levels, up to 300kVA, and uses
common motor control software for efficient control of IPM or induction motors.
At Electric & Hybrid Vehicle Technology
Expo, the company will present a demonstration of one of its inverters driving
a motor.
