摘要： A battery module includes a plurality of cells accommodating an electrode plate group and an electrolyte, and a single integrated battery case for accommodating the plurality of cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99-40:60 at a temperature of 25° C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.

摘要： A power supply system for portable equipment has a lithium-ion secondary battery as a power supply, a temperature detection portion for detecting a temperature of the power supply, a voltage detection portion for detecting a voltage of the power supply, a memory portion, and a forced discharge portion. The memory portion stores a control operating temperature, a control operating voltage and a control termination voltage. The forced discharge portion recognizes an abnormality of the power supply when the temperature of the power supply is at least the control operating temperature and the voltage of the power supply is at least the control operating voltage. Then, the forced discharge portion electrifies the notification portion and makes it inform a message indicating that the abnormality is being avoided. The forced discharge portion forcedly discharges the power supply until the voltage of the power supply reaches the control termination voltage.
