The R&S NGL200 and the new R&S NGM200 series offer the same superb performance and specifications to supply extremely stable outputs with a minimum of residual ripple and noise. Devices that switch from a few microamps in sleep mode to several amps in active mode benefit from the exceptionally fast load recovery time of less […]
How bidirectional converters speed the design of dual-battery automotive systems
New standards for combined 48-V/12-V vehicles dictate stringent tests for overvoltages and currents that new converter ICs can help meet. Tony Armstrong | Analog Devices Inc. The 48/12-V automotive battery system is just around the corner. Most major automobile manufacturers have been perfecting such systems for past few years, and it is evident that their […]
Want a new perspective on battery management? Buy a plug-in EV.
One facet of EV ownership: Thinking of your daily commute power consumption as equivalent to the sunlight hitting 20 ft2 of your lawn. Rudye McGlothlin, Silicon Labs Earlier this year I took my first step into the EV future by buying a plug-in hybrid electric vehicle (PHEV) – a Chevrolet Volt. A unique car in […]

Researchers at The Hong Kong Polytechnic University (PolyU) say they have developed a highly flexible, high-energy lithium battery for wearable electronics with a myriad of applications. PolyU’s novel lightweight Textile Lithium Battery demonstrates an energy density of more than 450 Wh/L and flexibility — with a bending radius of less than 1 mm and foldability […]
Battery self-discharge and designing for long life
Battery chemistries each have special qualities that can make certain cells impractical for varying kinds of internet-of-things applications. Sol Jacobs | Tadiran Batteries Circuit designers often find themselves in the position of trying to squeeze as much life as possible out of a battery. Today there is much discussion about boosting battery life through use […]
CR123A battery holder has an ultra low profile
The BH123A is an ultra-low-profile battery holder for “123A” batteries. The battery is flush with the PCB surface, so it adds no height to a CR123A cell when mounted on a circuit board. Use multiple holders, wired thru the PCB for serial or parallel connectivity options. The battery holder is made of premium materials like […]
Small lithium-ion rechargeable batteries feature high discharge/charge rates
Nichicon Corp. has developed the new Small Lithium-Ion Rechargeable Battery (SLB series) in conjunction with Toshiba Infrastructure Systems & Solutions Corp. SCiB technologies. Features The main feature of the SLB series includes: 1) A high rate of charge/discharge. The batteries are able to charge to approximately 80% in three minutes and discharge to 95% of […]
Maximizing efficiency and safety with rechargeable batteries
Some rechargeable lithium battery chemistries need more TLC than others when it comes to safety precautions. TOM BLAHA, MEMORY PROTECTION DEVICES RECHARGEABLE BATTERY TECHNOLOGY has come a long way, continually boosting performance with fewer annoying memory effects that severely limited the useful operating life of earlier generation cells. The most common rechargeable battery chemistries commercially […]
How long can a battery really last?
It pays to know how a testing regime can reveal whether specific types of lithium batteries will last as long as an application demands. SOL JACOBS, TADIRAN BATTERIES DESIGNERS MUST UNDERSTAND how their end device will consume power before they can choose a battery. Will the battery be depleted in a matter of hours, as […]
