Running a laptop or other electrical equipment causes a problem when there is no access to a mains supply. If the battery runs out, where can you recharge it?
The Mobile Power Box has been developed at the Fraunhofer Institute for Solar energy systems ISE working in cooperation with the firm of Masterflex. It is a membrane fuel cell system supplying mains-free energy in the medium power range.
Though many people have never heard of them, the emerging realm of micro-scale devices - called microelectromechanical systems, or MEMS - could change the medical, automotive and aerospace industries, except for one thing
Mastervolt has introduced three battery chargers: the IVO Smart 12/10, 24/6 and 12/15-2. Making use of high frequency switchmode technology the models are ultra compact and lightweight while providing power, correct charging and battery maintenance.
APC in Australia and New Zealand has announced a voluntary recall of two specific models in its Back-UPS CS uninterruptible power supply (UPS) line due to potential safety issues that may result in over heating and represent a potential fire hazard.
The battery has the inherent problem of not being able to communicate with the user. Neither weight, colour, nor size provides an indication of the battery's state-of-charge and state-of-health. The user is at the mercy of the battery
Electrical energy from non-rechargeable (primary) batteries is very expensive, and many organisations are switching to rechargeable (secondary) batteries. This article examines the advantages, limitations and economics of primary and secondary batteries
