Capacitor unit with electric double layer capacitors, control method and control apparatus for the same, and accumulator system for motor vehicles

摘要

A capacitor unit (1) with plural double layer capacitors (11) eliminating irregularity in a state of charge of the respective double layer capacitor (11) in the capacitor unit (1). A capacitor unit (1), a capacitor unit control method, a capacitor unit control apparatus (2) and a vehicle charging system, wherein a chargeable and dischargeable capacitor unit (1) with plural electronic double layer capacitors (11) connected in series is characterized in that electric double layer capacitors (11) in a higher state of charge is subject to discharge so that a state of charging of the respective electric double layer capacitor (11) may become approximately equal to each other.
