Regenerative DC Emulator
Keysight Technologies (Santa Rosa, CA) offers an enhanced Scienlab Regenerative DC Emulator (SL1800A Series), the next
generation high power direct current (DC) emulator for EV fast charging applications that enables customers to achieve highpower
DC charging test up to 270 kilowatts (kW) in a small footprint. Typical high-power DC test systems are large and occupy
valuable lab floor space. These systems are also inefficient, requiring large amounts of energy to run the test system and to keep
the lab space cool during high-power tests. When performing high-power DC fast charging tests, customers need a solution that
combines the needed power requirements with communication tests and monitoring that is easy to set up and use. The Scienlab
Regenerative DC Emulator enables customers to realistically emulate high-voltage, high-power EV batteries in charging test
applications, such as high-power DC fast charging, when paired with Keysight's SL1047A Scienlab Charging Discovery System. This solution can emulate
EV batteries up to 1500 volts, up to 900 amperes, and can be paralleled to achieve up to megawatts (MW).

Multicell Battery Monitoring
STMicroelectronics (Coppell, TX) L9963E Multicell Battery Monitoring & Balancing IC is a Li-ion battery
monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up
to 14 stacked battery cells can be monitored to meet the requirements of 48V and higher voltage systems.
Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The
device can monitor up to seven NTCs. The information is transmitted through SPI communication or an isolated interface. Multiple L9963E can be connected
in a daisy chain and communicate with one host processor via the transformer isolated interfaces, featuring high-speed, low EMI, long-distance, and reliable
data transmission. Passive balancing with programmable channel selection is offered in both normal and low power mode (silent balance). The balancing
can be terminated automatically based on internal timer interrupt. Nine GPIOs are integrated for external monitoring and control. The STMicroelectronics
L9963E features a comprehensive set of fault detection and notification functions to meet the safety standard requirements.

Pressure-Reducing Regulator
Emerson (St. Louis, MO) has launched a pressure-reducing regulator
specially designed for use onboard commercial hydrogen fuel cell vehicles.
The dual stage and patented active seal design of the TESCOM™ HV-3500
Hydrogen Onboard Regulator delivers steady pressure and constant hydrogen
fuel supply to fuel cells in the full range of vehicle operating conditions, including
acceleration, deceleration, stopping and idling. Stable pressure aids in
extending fuel cell life and maximizing fuel usage. The reliable fuel pressure
provided by the HV-3500 allows operators to drive farther without refueling
and decreases the risk of over pressurization downstream, resulting in leakage, wasted fuel and possible
emissions. The HV-3500 has been designed, engineered, and independently tested to ensure compliance
with EC79 requirements for pressure regulators used in hydrogen vehicles. By boosting fuel cell
efficiency and maximizing overall energy efficiency, the stable pressure the HV-3500 provides also
reduces maintenance frequency. The regulator delivers positive high-pressure fuel shutoff of hydrogen
in vehicles across varying road and operating conditions, increasing fuel cell durability.

Modular Battery Energy Storage System
Developed by Advanced Battery Concepts (Clare, MI) " Box-Be " - a
BOX of Bipolar Energy - is a modular Battery Energy Storage System.
This system is powered by our Advanced BiPolar EverGreenSeal™ technology
and is designed to meet the energy needs of today and future
generations. The design of BOX-BE allows for easy and safe scalability
while providing high power and energy for long-duration discharges.
Its simple parallel connections enable seamless field installation. It
supports a seamless expansion of energy storage capacity and charging duration with a self-contained,
self-regulated DC battery pack. BOX-BE plug and play design allows for easy and simple connection to
adjacent units. The non-flammable chemistry is incapable of thermal self-ignition, assuring safety and
peace of mind over the lifetime of the system. BOX-BE units are recovered and nearly all components
are processed and reused. Disassembly and recovery of parts consumes little energy and virtually no
waste, making BOX-BE the ideal green energy storage technology for carbon footprint reduction.
