Pre-qualified lithium-ion batteries target medical device design applications
November 22, 2013 // Paul Buckley
UK-based battery specialist, Accutronics, has launched a new range of pre-qualified and pre-tested batteries. The new customisable VR420 batteries are ideal for applications such as medical equipment and industrial electronics.
The range is designed, developed and manufactured by Accutronics in the UK and meets all relevant safety, performance and transportation standards.
The 14.4 V batteries utilize lithium-ion technology to deliver high volumetric and gravimetric energy density so that equipment runs for longer yet weighs less.
The VR420 includes a SMBus (System Management Bus), SBS (Smart Battery System) compliant impedance tracking fuel gauge that allows the battery to communicate pertinent battery data between itself, a smart host and a smart charger. When configured in a product, the host equipment is able to easily request dynamic information from the battery such as runtime to empty, cycle count and discharge current as well as static information such as serial number, manufacturer name and part number. The data allows the customers device to better manage its own power which can increase device runtimes and reduce the number of premature device shutdowns. Additionally, a five bar LED display on the battery case allows the user to easily determine the state of charge in simple 20% increments.
The VR420 includes its own active and passive protection devices which prevent it from being over-charged, over-discharged or overloaded in an abuse condition. Holding safety certification to IEC62133 and UL2054, the VR420 is easily designed into new devices with minimal time and cost.
Designed for rugged work environments the VR420 features a black flame retardant plastic housing which includes a polarised rail feature down either side so the VR420 can be slid into a host device with minimal effort.
Transportation of the VR420 is simplified as the product has a stored energy of less than 100 Watt-Hours and it has been independently certified to the Manual of Tests and Criteria (ST/SG/AC.10/11/Rev5) section 38.3.
The VR420 is available in two versions; VR420A and VR420B, supplying 6.2 Ah and 4.4 Ah respectively. The ‘A’ version provides highest capacity, whilst the ‘B’ option is optimized for higher discharge applications such as motor driven ventilators, where a considerable amount of power is required quickly.
The VR420A and VR420B can be purchased off the shelf or customised to suit a particular customer need.
