Battery Charger IC
ROHM Semiconductor (Santa Clara, CA) introduced the BD71631QWZ battery charger IC for low-voltage charging
of wearables and thin, compact IoT devices powered by rechargeable batteries. It charges lithium-ion and other
types of rechargeable batteries such as all-solid and semi-solid-state. It achieves low-voltage charging over a range
from 2.0 V to 4.7 V by improving the stability of the internal circuit. Charge voltage can be set by changing the external
resistor. Each charging characteristic can be set for CC/CV charging.

Battery Backup Units
Green Cubes Technology (Kokomo, IN) announced Guardian lithium-ion battery backup units for rackmount installations
such as telecom and data centers. The family consists of three sizes ranging from 2-RU to 4-RU heights that
fit in 19 " or 23 " cabinets and support capacity ranges from 105 Ahr to 175 Ahr. The batteries provide a nominal
48 V output and charge and discharge up to 100 Amps. Each battery also contains an integrated Battery
Management System (BMS), charging electronics, and proprietary Energy Balancing Technology (EBT) that enables
active current control, load sharing, and State of Charge balancing across connected units. They feature either lithium
nickel manganese cobalt or lithium iron phosphate chemistries.

Battery Management System
The i-BMS battery management system from Sensata Technologies (Swindon, UK) is designed for electrified applications
up to 60 V. It is cell-chemistry-agnostic and features hot swap functionality to quickly exchange depleted batteries
with fully charged batteries. Parallel pack support allows the use of two or more battery packs in parallel. The
PCB board includes integrated pre-charge circuit, onboard current measurement, MOSFET power switches for battery
disconnect, and a DC/DC power supply.

Power Supplies
AutomationDirect (Cumming, GA) offers RHINO SELECT open
frame and panel mount power supplies with integrated UPS functionality
that provides seamless battery switchover to keep critical
operations running when there is an unexpected loss of power. The
industrial power supplies provide TTL status outputs for external
monitoring systems and are UL 60950-1 and UL 62368-1 recognized,
CE marked, and RoHS compliant. The PSB24-240-1 DIN Rail mount power supply incorporates
Power Boost Technology, a short-term power used to support high inrush current.

Battery Contact
The 230-1 universal offboard battery contact from Keystone
Electronics (New Hyde Park, NY) is designed for AAA, AAAA, N, and
12-V battery cells. The symmetrical design allows the contact to
function both as a positive and negative contact, eliminating the
need to specify two different parts. This contact is manufactured
from .008 " (0.20 mm) thick spring steel and is nickel-plated for corrosion protection, flexible contact,
and low contact resistance. It is designed to free up board space by permitting offboard edge
mounting that affords reliable connection and easy access to install and replace batteries.

Adhesive
Dymax (Torrington, CT) introduced 9501-F adhesive for electric
vehicle battery assembly. The low-shrinkage product bonds securely
to common substrates such as PC, PC/ABS, nickel plated steel, and
aluminum and is designed for fixturing cylindrical battery cells to
plastic bases and holders. It cures tack-free in seconds upon exposure
to UV/visible light energy and is also LED curable at 385-nm wavelength. The solvent-free, onecomponent
acrylated urethane has viscosity of 10,000 cP and fluoresces bright blue in color.
