The battery pack is a mystical black box that does not change size, weight and colour during its lifetime. Neither does it reveal the charge level and state-of-health. And yet, the battery plays a key role in many portable applications
PrOffice 650 is a 650 VA standby UPS with five Australian three pin socket outlets (three UPS supported and all with surge protection). The 650 UPS also has surge protection for telephone equipment (one in and two out sockets). The unit is supplied with downloadable shutdown software and will support both USB and RS232 communication interfaces.
The GME switchmode voltage converters feature intelligent monitoring circuitry for 'soft-shutdown' to completely avoid short-circuit, overload and wiring fault problems protecting not only the equipment driven, but also the vehicle wiring and systems.
For most electronic systems, monitoring system voltages with a power-on reset (POR) ensures proper initialisation at power-up
For most electronic systems, monitoring system voltages with a power-on reset (POR) ensures proper initialisation at power-up. Detecting brownout conditions with a POR minimises possible code-execution problems that can corrupt memory
Biophan Technologies, a US company, has developed the Biothermal battery, based on the use of thermoelectric materials, using nanoscale-based, thin-film materials to convert thermal energy produced naturally by the human body into electrical energy.
Toshiba has announced the prototype of a highly compact direct methanol fuel cell (DMFC) that can be integrated into devices as small as digital audio players and wireless headsets for mobile phones.
During the last 20 years, three basic battery rapid test methods have emerged. All methods are resistance based, a characteristic that reveals the battery's ability to deliver load current
The Motech PPS-120X GSM series dual channel DC source/current sink power supply/loads are suitable for testing mobile phone and other battery operated equipment, especially systems incorporating rechargeable batteries - in this case the device supplies charging power while checking battery drain at the same time.
Perth company Hitec Energy has been offered an Australian Government R&D start grant for a mineral extraction process that produces the key ingredient for alkaline batteries in a more cost-effective way.
