Micro Power has secured two patents designed to improve the safety and reliability of portable battery packs used in mission-critical operations. The patents will be used in battery-pack designs for medical and military original equipment manufacturers, the company says.

The first patent is a redundant battery-protection system and method. The enhanced protection system includes a primary protection circuit and a redundant protection circuit as a backup if the primary fails. The patent ensures that battery packs will operate when called into action, even if there is a component failure that would typically fail a conventional battery.

The second patent is for an electrical insulation system and method for power storage component separation. The insulation system uses a polyurethane elastomer material to electrically separate various components of electrical power within battery packs. The polyurethane elastomer can be used to insulate cells, connecting tabs, printed-circuit assemblies, solder joints, nickel strips, and other conductive members within the battery pack. It also ensures performance under abusive conditions such as shock or vibration.
