  "textContent": "Provided is a device for detecting the state of health and the state of charge of a power storage element, which is capable of accurately and instantaneously detecting the state of health SOH and the state of charge SOC of a power storage element, thereby enabling recognition of a battery state. A detection device 1 for detecting the state of health and the state of charge of a secondary battery 10 detects the state of health SOH and the state of charge SOC and comprises a measuring means for measuring a voltage and a current of the secondary battery 10; and a control unit having a calculating means for executing a predetermined calculation. The control unit 14 determines overvoltage δ during operation of the secondary battery by calculation based on measured values of rising voltage and current at a start of charging of the secondary battery according to the battery equation shown in [Math. 1].",
