A parameter determination unit (312) in a battery protection device (30) in an electricity storage system determines whether or not a custom parameter set by a user can be used. When the custom parameter can be used, a parameter selection unit (313) uses the custom parameter, and when the custom parameter cannot be used, the parameter selection unit (313) uses a preliminarily set internal parameter for carrying out the minimum required operation. A main processing unit (314) executes a protection process on the basis of the selected parameter. When the custom parameter cannot be used, an auxiliary setting unit (317) outputs a message prompting input of a custom parameter to the user interface. A breaker control unit (316) turns off a breaker (20) when a set time period has elapsed since notification of the message without any input of a custom parameter. |
