To make use of the strong advantage of electric double layer capacitors (EDLCs), the authors developed two EDLCs; a rapid type EDLC of 0.1 ΩF class and a higher temperature durable type EDLC at 105 °C. The time constant (ΩF) of the rapid type EDLC was far lower than that of a conventional one because it has thin carbon layers on the electrodes and low resistance especially between the current collector and the electrode. An elliptical spiral type EDLC (160 F class) and a module (40 cells) was developed. Most of the electrical energy that is produced when a motor starts and stops (regenerative energy) goes to waste as heat. To save on the electrical power requirement of a motor, a device with rapid (<1 second) charge and discharge energy storage (0.1 ΩF class) is necessary. Durability at high temperatures is required for an electric power storage device placed near the motor and the power electronics devices. An elliptical spiral type EDLC (1000 F class) that is durable at 105 °C and a module (10 cells) was developed. The EDLC modules were connected in parallel with lithium ion battery modules, and were charged and discharged at 10-mode (one of the running patterns of a car). It could extend the life of the lithium ion battery by sharing the current with the EDLC.
