PISCATAWAY, N.J. — The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, Wednesday announced updates to its Battery Interface Specification (BIF) for mobile devices.
The new specification, MIPI BIF v1.1, makes it more practical and convenient for manufacturers to implement “smart” features in device batteries, facilitates the use of new high-performance batteries, and adds communications methods that improve battery safety and overall performance.
The MIPI BIF specification is a single-wire hardware and software interface for connecting a power management chip in a phone to a smart or low-cost rechargeable battery. It is the only mobile-to-battery communication interface specification in the industry, offering manufacturers a uniform solution to replace proprietary interfaces.
It also provides the communications and intelligence capability needed to measure fundamental battery operational conditions, such as temperature, or to verify a battery’s authenticity. The adoption of MIPI BIF in the mobile industry has also enabled manufacturers to offer interoperable battery products, reduce chipset space and streamline design, implementation and testing of their components to accelerate product time-to-market while lowering costs.
