Next time you find yourself swimming around with electric eels, try grabbing one and then put the leads of a battery powered oscilloscope on its head and tail. According to University of Central Florida zoology professor Will Crampton, you’ll probably measure a voltage in the 700-V range. Crampton and his associates went to the rivers […]
Researchers get a charge out of measuring eels with battery powered oscilloscopes
Next time you find yourself swimming around with electric eels, try grabbing one and then put the leads of a battery powered oscilloscope on its head and tail. According to University of Central Florida zoology professor Will Crampton, you’ll probably measure a voltage in the 700-V range. Crampton and his associates went to the rivers […]
Battery-powered scopes hit 150 MHz bandwidth
The Micsig STO1000E PLUS series of two- and four-channel battery-powered portable oscilloscopes offer bandwidths of up to 150 MHz. The three models in the series are: STO1102E PLUS 2-channel 100 MHz, STO1152E PLUS 150 MHz 2-channel, and STO1104E PLUS 4-channel 100 MHz. Each oscilloscope includes 70 Mpt memory, 1 GSa/sec sampling (single channel), 130,000 wfm/sec […]
Applying large banks of supercapacitors
It pays to know techniques for mitigating leakage current and over- voltages in uses where several supercapacitors work in parallel. Michele Kinman Advanced Linear Devices Inc. In applications requiring rapid charge/discharge cycles or short-term energy storage, you’ll often find supercapacitors connected in series or parallel. However, there’s a potential problem when supercaps are wired together […]
The 40-year battery pack
Not all primary batteries offer the low annual self-discharge rate needed for the lengthy lifespan of remote wireless devices consuming microamp-level currents. Sol Jacobs, Tadiran Batteries The vast majority of remote wireless devices are powered by primary (non-rechargeable) batteries that range from consumer-grade to industrial grade. Consumer-grade alkaline batteries deliver higher discharge rates of energy, […]
E-plane maker bets LiS battery technology could double the range of electric-powered flight
The best commercial lithium-ion batteries today deliver energy densities of around 250 Wh/kg. But battery chemistry oriented around lithium-sulfur could deliver double that figure. This potential improvement has brought electric plane-maker Bye Aerospace in Colorado to work with UK-based Oxis Energy on LiS cells able to provide in excess of 500 Wh/kg at 20-Ah capacity. […]
Better battery management: New technique measures electrochemical impedance of multi-cell stacked lithium-ion batteries
Researchers at Panasonic Corp. and Ritsumeikan University say they have developed a new battery management technology that measures a battery’s electrochemical impedance, which is an effective method of evaluating the residual energy of lithium-ion batteries in use. The technique is expected to be applied in applications characterized by numerous battery cells stack in series. Panasonic […]
Energy efficient supercapacitor cell balancers include over-voltage protection
The precision dual-channel SABMBOVP2XX family of products automatically balances supercapacitors with the addition of over-voltage protection (OVP). The result is energy-efficient supercapacitor balancing, ideal for products that require low-loss energy power, leakage current regulation, and OVP. Supercapacitor cells typically operate at a nominal recommended working voltage. However, voltages that exceed the maximum rating for a […]
Lithium-water rechargeable batteries said to be safer, more energy dense than lithium-ion
A new high-performance Lithium-water (Li-water) rechargeable battery technology has been developed for the energy storage and mobile device markets. According to co-developers Global Technology Systems, Inc. (GTS) and Dr. Boris Tsenter, the new Lithium-water technology will be safer, with longer run times and lower environmental impact than traditional Lithium-ion battery technology. The technology is expected […]
NiMH battery packs operate over wide temperature range
NiMH cells and finished battery packs offer two important features in conjunction with each other: Good performance at low temperatures and long life at high temperatures. Panasonic, one of the world’s leading battery manufacturing companies, a variety of NiMH cells with wide temperature ranges. These cells provide new electrode development which allow for a wide […]
