Abstract:
1. An electronic apparatus comprising: a current detection unit that detects a current flowing from a battery to the electronic apparatus; a voltage detection unit that detects a voltage of the battery; a detection unit that detects a remaining level of the battery based on a first current value, a second current value, a first voltage value, and a second voltage value; and a control unit that stops flowing abnormal current from the battery to the electronic apparatus by controlling a switch unit to disconnect between the battery and a load unit of the electronic apparatus if a current detected by the current detection unit is not less than a predetermined value, wherein the switch unit is connected between the battery and the load unit, the control unit that does not control the switch unit to disconnect between the battery and the load unit if a current detected by the current detection unit is less than the predetermined value, the first current value is detected by the current detection unit if the electronic apparatus is in a first state, the second current value is detected by the current detection unit if the electronic apparatus is in a second state, the first voltage value is detected by the voltage detection unit if the electronic apparatus is in the first state, the second voltage value is detected by the voltage detection unit if the electronic apparatus is in the second state, the second state is different from the first state, and the first current value is less than the second current value.
