Claims (1)

[Scope of utility model registration request] In an electric vehicle driven by an electric motor that uses a battery as a power source, there is a current circuit that detects the discharge current to the motor, compares it with a set value, and outputs a binary signal of a signal above and below the set value, and a current circuit that detects the battery voltage. A voltage circuit that compares with a set value and outputs a binary signal of a signal above the set value and a signal below the set value, a logic circuit that outputs an abnormality signal that waits for simultaneous input of signals below the set value from both circuits, and An electric vehicle comprising an alarm driven by a signal, and a delay circuit interposed between a current circuit and a logic circuit to delay a change in a current circuit output from a signal above a set value to a signal below a set value.
