Abstract: Provided is a system including: a management unit configured to manage a plurality of battery packs connected in parallel, in which the management unit is configured to control the plurality of battery packs to cause the plurality of battery packs to be discharged alternately so that a discharge rate of each of the plurality of battery packs becomes higher than the discharge rate in a case of discharging all of the plurality of battery packs. The plurality of battery packs include a plurality of left-hand side battery packs and a plurality of right-hand side battery packs, and the management unit is configured to manage the plurality of battery packs to cause at least one of the plurality of battery packs in each of the plurality of left-hand side battery packs and the plurality of right-hand side battery packs to be discharged at a time in order.

Abstract: An active material used in a secondary battery includes a heterocyclic chemical compound including one or more pyrazine rings and two or more benzene rings, or a salt or derivative thereof. The heterocyclic chemical compound is preferably a chemical compound in which at least 4 oxygen atoms are bonded to the benzene ring. The active material used in the secondary battery may also include phenazine or a salt or derivative thereof. The phenazines are preferably chemical compounds in which at least 4 oxygen atoms are bonded to a benzene ring included in a phenazine structure.
