A charger that charges a battery unit including a secondary battery, includes a receiving unit, a detection unit, a determination unit, and a control unit. The receiving unit receives, from the battery unit, battery state information indicating a state of the battery unit, if the secondary battery is being charged. The detection unit detects charge state information indicating the state of the battery unit, if the secondary battery is being charged. The determination unit determines, using the battery state information and the charge state information, whether the battery unit is in a normal state. The control unit controls charging of the secondary battery in the battery unit depending on whether the battery unit is in the normal state.

1. A charger comprising: a charging unit that charges a battery device including a battery;a communication unit that receives first information indicating a temperature of the battery detected by the battery device from the battery device;a first detection unit that detects second information indicating a temperature of the battery;a second detection unit that detects third information indicating a voltage between terminals for connecting the battery device; anda control unit that (a) controls, using a value obtained based on the first information and the second information, charging of the battery device if the charger and the battery device are connected, and (b) controls, using a value obtained based on the third information and fourth information indicating a voltage of the battery detected by the battery device, charging of the battery device if the charger and the battery device are connected. 2. The charger according to claim 1, wherein the value obtained based on the first information and the second information is a difference between a first temperature indicated by the first information and a second temperature indicated by the second information. 3. The charger according to claim 2, wherein the first temperature includes a temperature corrected using the first information, and the second temperature includes a temperature corrected using the second information. 4. The charger according to claim 1, wherein the control unit stops charging of the battery device if the value obtained based on the first information and the second information is not less than a first predetermined value. 5. The charger according to claim 1, wherein the value obtained based on the third information and the fourth information is a difference between a first voltage indicated by the third information and a second voltage indicated by the fourth information. 6. The charger according to claim 5, wherein the first voltage includes a voltage corrected using the third information, and the second voltage includes a voltage corrected using the fourth information. 7. The charger according to claim 1, wherein the control unit stops charging of the battery device if the value obtained based on the third information and the fourth information is not less than a second predetermined value. 8. A method for controlling a charger comprising: charging a battery device including a battery;receiving first information indicating a temperature of the battery detected by the battery device from the battery device;detecting second information indicating a temperature of the battery; anddetecting third information indicating a voltage between terminals for connecting the battery device;controlling, using a value obtained based on the first information and the second information, charging of the battery device if the charger and the battery device are connected; andcontrolling, using a value obtained based on the third information and fourth information indicating a voltage of the battery detected by the battery device, charging of the battery device if the charger and the battery device are connected. 9. The method according to claim 8, wherein the value obtained based on the first information and the second information is a difference between a first temperature indicated by the first information and a second temperature indicated by the second information. 10. The method according to claim 9, wherein the first temperature includes a temperature corrected using the first information, and the second temperature includes a temperature corrected using the second information. 11. The method according to claim 8, further comprising stopping charging of the battery device if the value obtained based on the first information and the second information is not less than a first predetermined value. 12. The method according to claim 8, wherein the value obtained based on the third information and the fourth information is a difference between a first voltage indicated by the third information and a second voltage indicated by the fourth information. 13. The method according to claim 12, wherein the first voltage includes a voltage corrected using the third information, and the second voltage includes a voltage corrected using the fourth information. 14. The method according to claim 8, further comprising stopping charging of the battery device if the value obtained based on the third information and the fourth information is not less than a second predetermined value.
