Method for Preventing High Temperature Self Discharge in Primary Battery
20170271688 · 2017-09-21 ·

A discharge prevention system for a primary battery comprises an energy harvesting module that produces energy from an environment and a control circuit for applying electrical current to the primary battery from the energy harvesting module to prevent or reduce self-discharge. This system will prevent or reduce rapid self-discharge at high temperatures in lithium-based primary batteries, for example. It can significantly extend the operating lifetime of such batteries operating at high temperature, particularly in applications where battery power is used intermittently. Specifically, a very low current is supplied to the primary battery at high temperature, significantly extending its storage lifetime. In some cases, depending on the current characteristics of the battery, the energy associated with the bias current can be in the same order of magnitude as the energy that would be lost by self-discharge, but in many cases it is much lower. This bias current “biases” the battery in such a way that self-discharge current of the primary battery is minimized.
