The present invention is to provide a display for a secondary battery in response to the status thereof. For this end, the secondary battery is provided with the display section including LEDs and the switch. If the switch is operated while the secondary battery is being exhibited in a shop, displays to give an image what happens after purchase of the secondary battery are preformed in the display section. Such displays differ from each other in the charging mode and the discharging mode of the secondary battery. For example, in the charging mode, LEDs are sequentially lighted to indicate that the secondary battery is being charged. Additionally, by controlling the LEDs based on the timing calculated from the charging current magnitude through the secondary battery, it is possible to indicate such information if the charging is approaching to the final stage.

A data carrier system is comprised of a vehicle-side controller,mounted at a vehicle,, keys,A and,B, and an R/W device,installed in an office,. A transponder,is built into each of the keys,A and,B. In this structure, after operational data has been transmitted from the vehicle-side controller,and written in a nonvolatile memory of the transponder,, when the keys,A and,B are inserted in the R/W device,by a vehicle driver, the R/W device,reads the operational data from the transponder,and gives the same to a personal computer,. Accordingly, an inconvenience of the vehicle driver carrying an IC card for recording operational data is removed.

Data carrier system

When an engine is started with a key,A inserted in an ignition key cylinder of a vehicle,, a vehicle-side controller,transmits operational data to the key,A and stores in the key,A. Further, when a personal computer,is operated with the key,A inserted in an R/W device,, the R/W device,reads the operational data from the key,A and transfers to the personal computer,. In this structure, when a storage capacity of the key,A becomes full, the vehicle-side controller,stores the operational data in a storage portion of its own, and when the key,A is initialized, the stored operational data is written in the key,A. For this reason, even when initialization of the key,A is difficult, deletion of the operational data is prevented.

An electrical control unit for a vehicle successively writes operation data of the vehicle in a transponder provided in a key used for starting the vehicle. At the same time, the electric control unit successively writes the same operation data in a memory area of a non-volatile memory corresponding to a key used for starting the engine. When the key is lost, the engine is started under the condition that the identification of the lost key is written in a replacement key. Then, the electric control unit of the vehicle writes operation data stored in the non-volatile memory corresponding to the lost key in the replacement key. At the same time, the electric control unit of the vehicle moves the operation data to a memory area corresponding to the replacement key. Accordingly, when the operation data is read from the replacement key, operation data stored in the lost key can be managed.

A vehicular door lock control apparatus for unlocking a door lock mechanism includes a key for performing a first unlocking operation and a second unlocking operation. A door key cylinder is actuable to an unlock position by using the key. The key is insertable into the door key cylinder. A transmitter-receiver is disposed at the key, and transmits an answer signal that indicates a specific identification code upon receipt of at least one of a power signal and an inquiry signal. An operating force transmission mechanism, actuable between a transmission mode and a non-transmission mode, transmits an unlocking force applied by the key during the second unlocking operation to the door lock mechanism when in the transmission mode. A control mechanism transmits at least one of the power signal and the inquiry signal to the transmitter-receiver when the key performs the first unlocking operation, and actuates the operating force transmission mechanism to the transmission mode when the identification code received from the transmitter-receiver conforms to a pre-set identification code.
