Battery design for powering tiny devices
05 April, 2003Though 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
Electronic battery chargers
11 February, 2003Mastervolt 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.
Is the 'smart' battery a help or deterrent?
05 January, 2003 by Isidor Buchmann*, President, Cadex Electronics IncThe 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
Will rechargeables replace the primary battery?
05 June, 2002Electrical 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
