During the Wireless Japan 2008 conference held this July 22 to 24, NTT DoCoMo exhibited its intelligent Li-ION battery for mobile phones. The idea is to detect troubles within the Li-ION battery and relay it to the user. For that purpose, a 8-bit microcomputer has been embedded onto the pack and is responsible for monitoring such battery conditions as current, voltage, temperature, state of deterioration, remaining battery level. Once a problem is detected, user would get an information projected on screen.
Best of all, the battery’s status is stored on the battery itself, so even if a user change (buy used) phones, he/she can still view prior recorded data.
In the development process, NTT DoCoMo has been working alongside Mitsumi Electric. The leading Japanese mobile operator plans to use the new intelligent batteries on its next year’s phone models.
