<p>PROBLEM TO BE SOLVED: To provide a charging controller which can rapidly elevate the temperature of a cell pack used in an electric vehicle, etc. SOLUTION: A charging controller has resistances R1-R4 connected in parallel with the cells C1-C4 of a cell pack in which the plurality of cells C1-C4 are connected in series with one another and an A/D voltage converter 24 which detects the voltages of the cells C1-C4, and performs control to cause the charging currents of the cells C1-C4 to bypass to the resistances R1-R4 in accordance with the voltages Vc of the cells C1-C4 to make the charging rates of the cells C1-C4 uniform. In this case, a cell controller 2 which controls the charging currents so that when regenerative power during regenerative charging is greater than power that can be inputted by the cell pack, the charging currents bypass the interval between the terminals of the cell pack and flow to the resistances R1-R4, and a heating means for heating the cell pack by use of heat energy generated at the resistances R1-R4, are provided.</p> |
