Surface-mountable Li-ion battery protectors prevent overcharging damage
Littelfuse, Inc. announced the new ITV4030, a series of 22 amp, three-terminal, surface-mountable Li-ion battery protectors. These 4.0 x 3.0 mm devices protect battery packs against overcurrent and overcharging (overvoltage) conditions. The innovative design uses embedded fuse and heater elements that provide fast response and reliable performance to interrupt the charging or discharging circuit before the […]
Relays designed for higher reliability in isolated high-voltage environments
Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution […]
Battery Management Systems: Effective ways to measure state-of-charge and state-of-health
By Andrey Solovev, Chief Technology Officer, Integra Sources One of the purposes of battery management systems is to monitor the state-of-charge and state-of-health of rechargeable batteries. This article will tell you about these two metrics and the methods used to measure them. Rechargeable batteries are used in many solutions, but industries use battery management systems […]
New 9155 series 1.27mm-pitch board-to-board battery connectors
KYOCERA AVX has further expanded its well-proven portfolio of battery connectors for board-to-board and battery pack integration applications with the release of a new fine-pitch connector series designed for medical, industrial, and networking applications. The newest additions to this product portfolio, which already offered the broadest selection of standard battery connectors currently available on the market, are the […]
Thionyl Chloride batteries excel in asset tracking, high-power apps
Ultralife Corporation has extended its ER Generation X family of Lithium Thionyl Chloride (LiSOCl2) batteries for critical applications, with two new products added to the range of rugged, energy-dense batteries. The new additions are the low rate UHE-ER14250-X 1/2AA size bobbin cell for asset tracking and more, plus the high-rate UHR-ER18505-X A size spiral cell for […]
Battery management system uses ultra-thin pressure and temperature sensors
Innovation Labs has announced the BaMoS battery monitoring system that uses ultra-thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used to extend battery lifetime by up to 40 percent. The battery is the most important component in an electric vehicle (EV). Despite extensive […]
Modules help add wireless charging to small devices
Rohm Semiconductor announced they have developed compact wireless charger modules with an integrated antenna board: the BP3621 (transmitter) and the BP3622 (receiver). These new modules allow designers to add wireless power supply functionality to smaller devices such as smart tags/cards or PC peripherals. Wireless power supplies are increasingly being adopted in smartphones, smart watches, and other compact devices. […]
Compact contactors handle up to 250 A dc, 1,000 Vdc
TDK Corporation has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V […]
Current-sensing foil-on-ceramic resistors sport 2 milliohm resistance
High efficiency in consumer electronics has become increasingly important. For portable electronics, this means lower resistance values on current sense resistors for battery and power management. Stackpole’s CSRF series is a foil on ceramic carrier chip resistor that is designed for these applications. The CSRF2512 is now available in resistance values down to 2 milliohms. […]
