Hybrid power supply unit
View Patent ↗A hybrid power supply unit, comprises a high-capacity nonaqueous electrolyte battery group and a high-power nonaqueous electrolyte battery group different in discharge characteristics connected to each other in parallel. The high-capacity nonaqueous electrolyte battery group has a 0.2 C discharge capacity per cell greater than that of the high-power nonaqueous electrolyte battery group, and the high-power nonaqueous electrolyte battery group has a rate of 5 C discharge capacity per cell to 0.2 C discharge capacity per cell (5 C discharge capacity/0.2 C discharge capacity) greater than that of the high-capacity nonaqueous electrolyte battery group.
1. A hybrid power supply unit, comprising a high-capacity nonaqueous electrolyte battery group and a high-power nonaqueous electrolyte battery group different in discharge characteristics connected to each other in parallel, wherein;
a difference in electrode plate area per capacity between a positive electrode of the high-capacity nonaqueous electrolyte battery group and a positive electrode of the high-power nonaqueous electrolyte battery group is more than 100 cm 2 /Ah,
said high-capacity nonaqueous electrolyte battery group has a 0.2 C discharge capacity per cell greater than that of said high-power nonaqueous electrolyte battery group, and
said high-power nonaqueous electrolyte battery group has a rate of 5 C discharge capacity per cell to 0.2 C discharge capacity per cell (5 C discharge capacity/0.2 C discharge capacity) greater than that of said high-capacity nonaqueous electrolyte battery group.
2. The hybrid power supply unit according to claim 1 , wherein at least one of said high-capacity nonaqueous electrolyte battery group and said high-power nonaqueous electrolyte battery group contains multiple cells.
3. The hybrid power supply unit according to claim 2 , wherein said multiple cells are connected in series.
4. The hybrid power supply unit according to claim 2 , wherein said multiple cells are connected in parallel.
