る。Here, the reason why an electric double layer capacitor is applied to a main battery of an electric vehicle will be described. The electric double layer capacitor has a large capacitance, and since the generation of electric energy is due to ion transfer, it does not involve a chemical change of the substance at the time of generation of electric energy unlike a chemical battery such as a lead battery, so that deterioration is small. In recent years, it has attracted attention as a power source for electric vehicles because of its long life and the like.

Therefore, in order to obtain a power supply of about 300 V, in an electric double layer capacitor battery, 100 or more capacitor cells are connected in series. In order to operate the electric double layer capacitor for a long time without deterioration, it is necessary to make sure that the cell voltage does not exceed a specified voltage.

が数１０Ａ以上となっている。The electric double layer capacitor is characterized by being able to take out a larger output than a chemical battery. As described above, since the cell voltage of the electric double layer capacitor is as low as about 1 V to 3 V, the current is increased to increase the output. At present, the output current is several tens A or more.

いる。In a DC power supply for an electric vehicle or the like, 100 or more such high-output capacitor cells are connected in series. The problem here is that the connection conductor between the capacitor cells and the cell terminals are connected. This is the voltage drop at the connection with the connection conductor. If 150 capacitor cells are connected in series, the number of capacitor cell terminals becomes 300, and the number of connection conductors between the capacitor cells becomes 298. Since the connection resistance of the capacitor cell terminal portion is about several mΩ, the total of 150 leads reaches several hundred mΩ. The voltage drop due to this resistance reaches 20% or more of the DC voltage, causing a large resistance loss and greatly reducing the charge / discharge efficiency of the capacitor battery.

That is, the voltage drop rate (the ratio between the voltage drop and the capacitor terminal voltage) increases with discharge.

のである。[0010] A voltage drop occurs in the internal resistance of the capacitor battery, the terminal connection portion, and the connection conductor. Although the internal resistance of the capacitor cell can be improved by improving the performance of the cell itself, the one due to the terminal connection and the connection conductor cannot be improved.
In the future, in order to further increase the output of the electric double layer capacitor battery, the voltage drop problem other than the capacitor cell is a serious problem. Therefore, an object of the present invention is to provide an electric double-layer capacitor battery capable of increasing the output by minimizing a voltage drop at a terminal connection portion or a connection conductor.

For example, the circuit loss in the main circuit connection portion can be greatly reduced. The feature is that a plurality of capacitor cells are housed in one case, each cell is connected by the shortest connection conductor in the case, and the main terminal of the case is only two terminals of a positive electrode and a negative electrode. In this structure, an auxiliary terminal for connecting the overvoltage protection circuit is taken out to reduce a voltage drop in the terminal connection portion and the connection conductor.
