STATE DETECTION DEVICE OF BATTERY FOR VEHICLE

PROBLEM TO BE SOLVED: To read historical data recorded on an incorporated memory of a state detection device of a battery for a starter of a vehicle, with few components, because it leads to cost rise to prepare a switch, component of two-way communication, or connector since a communication request for reading the internal information of the state detection device of the battery for a starter is input from the outside in the conventional formation. SOLUTION: The state detection device of the battery for a vehicle performs the state detection of the battery for an engine starter of a vehicle which makes an engine a main power source. The drive electrical power is supplied from the battery, has a memory which records information about the status of the battery in the inside thereof, detects that an alternator works, and sends out the content of the memory outside in all or part of a service period by communication.
