摘要: An electronic device and a power adapter are provided. The power adapter comprises a power circuit, a main control circuit, a potential adjustment circuit, a current detection circuit, a voltage detection circuit and an output switch circuit. When a conventional charging or a quick charging is performed on the battery in the electronic device, the main control circuit determines whether the output current of the power adapter is greater than a current threshold according to the current detecting signal and determines whether the output voltage of the power adapter is greater than a voltage threshold according to the voltage detecting signal; if the output current of the power adapter is greater than the current threshold and/or the output voltage of the power adapter is greater than the voltage threshold, the main control circuit controls the output switch circuit to turn off the direct current output of the power adapter.

摘要: A device that controls charging and discharging of a lithium ion battery (3) that starts an engine starter (1), includes: a voltage sensor (S1) that detects the voltage of the lithium ion battery; a current sensor (S2) that detects the current of the lithium ion battery; and a control section (30) that controls charging and discharging of the lithium ion battery. The control section (30) calculates capacity degradation rates of a cathode and anode of the lithium ion battery based on detected values of the voltage sensor and the current sensor at the time when a first time has elapsed, and at the time when a second time longer than the first time has elapsed, from startup of the engine starter, and limits the charging and discharging of the lithium ion battery based on comparison results between the capacity degradation rates and determination criterion values.
