Energy Balance Calculator
Nexperia (Nijmegen, Netherlands) has released its latest Energy Balance Calculator.
A powerful web-based tool designed to assist battery management engineers in maximizing
the battery life of their applications. The calculator facilitates the integration
of Nexperia's Energy Harvesting PMICs into their systems by providing engineers
with precise data for informed decision-making. At the core of Nexperia's Energy
Harvesting PMICs is the Maximum Power Point Tracking (MPPT) algorithm, enabling
efficient energy harvest from the environment for various consumer electronics and
IoT devices. To utilize these PMICs at their full potential, the calculator works with
real-world technical parameters. It calculates the energy delivered to the load and the
energy compensation. Thus, offering insights into potential battery life extension or achieving energy autonomy. Engineers
can furthermore visualize system efficiency and precision through an efficiency curve provided by the tool.

Extreme Fast Charging
StoreDot (Irvine, CA) has unveiled a breakthrough concept for taking extreme fast
charging (XFC) capability from the cell to the vehicle level with its new I-BEAM XFCTM
concept, an innovative cell-to-pack (CTP) design that will accelerate the integration of XFC
into EVs. At the core of I-BEAM XFCTM sits StoreDot's proprietary 100in5 cell technology,
which enables charging 100 miles, or 160km of range in just 5 minutes. StoreDot's 100in5
electrodes are assembled into its new I-BEAM XFCTM cells, which are designed to be incorporated
directly into the battery pack. While standard cell-to-pack architectures aim to
improve range and energy density, StoreDot is also focusing on extreme fast charging with
its I-BEAM XFCTM concept. It leapfrogs the complexity and cost challenges of embedding
XFC capability at the vehicle level, allowing EVs to be charged even more rapidly.

Resettable Thermal Cutoff Device
Bourns, Inc. (Riverside, CA) announced its latest miniature resettable thermal cutoff
(TCO) device series, also known as mini-breakers, that are designed to control
abnormal, excessive current virtually instantaneously, up to rated limits. The Model
NX Series offers higher current-carrying capabilities combined with a very low-profile
package at a height of 0.94 mm and body width of 2.8 mm. These features make
this series an ideal overtemperature and overcurrent protection solution for lithium
polymer and prismatic cells in high energy density, smaller batteries such as next-generation
notebook PC and tablet battery cells, as well as handheld and wearable
electronics. The new series has current capabilities from 12 A to 20 A at 60 °C and is
available with or without welding projections. Providing design flexibility for a wide range of application environments, these
TCO devices are available with four trip temperature options of 77 °C, 82 °C, 85 °C and 90 °C - all of which operate within a
±5 °C tolerance. The Model NX Series also is designed with a high-rated corrosion resistant bimetal mechanism that delivers
enhanced endurance in humid environments compared to standard TCO devices.

Battery Management Test System
Rohde & Schwarz (Columbia, MD) is partnering with Analog Devices, Inc. for a wireless
battery management system (wBMS) technology which brings technical, environmental,
and cost advantages compared with wired battery management systems (BMS). The
technology is the first ISO21434 CAL4 compliant wBMS which adheres to the strictest
cybersecurity standards. It also meets high requirements in RF performance and robustness
to maximize battery capacity and lifetime value. Rohde & Schwarz has developed an
ultra-compact automated test equipment (ATE) system for wBMS. With this test setup, the
necessary wBMS module calibration, receiver, transmitter, and DC tests can be conducted
fast and executed reliably for verification in the lab as well as for production tests for high
yield. It consists of the R&S CMW100 radio communication tester, the R&S WMT wireless automated testing software framework,
and the new R&S ExpressTSVP universal test and measurement platform.
