Patent number: 9847563Abstract: A first power storage section and a second power storage section are connected in parallel. The first power storage section includes a first non-aqueous electrolyte secondary battery. The second power storage section includes parallel-connected second non-aqueous electrolyte secondary batteries. Each of the second non-aqueous electrolyte secondary batteries has a higher energy density than that of the first non-aqueous electrolyte secondary battery. In a case where the second power storage section is discharged at a current value corresponding to a first assumed maximum discharge current value, the parallel-connected number of the second non-aqueous electrolyte secondary batteries is set such that a discharge rate of each of the second non-aqueous electrolyte secondary batteries becomes the preset reference discharge rate or less.Type: GrantFiled: January 27, 2015Date of Patent: December 19, 2017Assignee: SANYO ELECTRIC CO., LTD.Inventors: Makoto Ochi, Hiromasa Sugii, Kazunobu Yokotani, Fumio Yasutomi, Noritake Okada
