PROTECTIVE APPARATUS FOR SECONDARY BATTERY |
摘要 |
Disclosed is a protective apparatus for a secondary battery (1) comprising a temperature sensing switch (2) turned on when the ambient temperature around the secondary battery (1) exceeds a predetermined temperature setting, and a discharging circuit (3) electrically connected via the temperature sensing switch (2) to the secondary battery (1), the discharging circuit (3) acting to discharchge said battery (1). The discharging circuit (3) contains a voltage sensing switch (32) turned on when the voltage applied to the discharging circuit (3) exceeds a predetermined discharge starting voltage, and a discharging resistor (33) serially connected to the voltage sensing switch (32). <IMAGE> |
