CHARGE/DISCHARGE CONTROLLER FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To charge/discharge power appropriately depending on the working environment and the state of a battery. SOLUTION: When the battery temperature is lower or higher than a specified level, upper and lower limits Pin-s, Pout-s of charging and discharge power are set lower than those for normal temperature. The battery temperature is detected and charging operation of the battery is controlled such that charge/ discharge power comes within the upper and lower limits Pin-s, Pout-s for that temperature.
