A device includes: a storage storing a distributed ledger, the distributed ledger including a plurality of evidence chains and a time stamp chain, the plurality of evidence chains storing in chronological order at least one hash value, the time stamp chain storing in chronological order at least one time stamp token; and a processor configured to repeatedly execute an update process such that the time stamp chain is updated, the update process including a process for identifying, out of the evidence chains, at least one evidence chain in which the hash value has been changed with a change in the file since previous execution of the update process, and acquiring the time stamp token for a terminal value generated based on a terminal hash value of the at least one evidence chain.

Data management device, data management method, and non-transitory storage medium

A data management system includes a plurality of data management apparatuses, a certification authority group, and a time stamp authority group. In making an application for a proof of existence of invention information, the data management apparatus generates an invention hash, and transmits the invention hash to selected time stamp authorities of the time stamp authority group. Each of the time stamp authorities having received the invention hash generates a time stamp token. The data management apparatus acquires the time stamp token from each of the plurality of time stamp authorities to which the invention hash has been transmitted.

Data management apparatus and data management method

When it is judged that a downward slope segment exists in a scheduled traveling route, the control device of a hybrid vehicle sets a target remaining capacity SOC* in a pre-use segment in a downward slope segment and the downward slope segment to a 'low-side remaining capacity Sd which is &#x394;Sd smaller than a standard remaining capacity Sn.' Furthermore, when it is presumed that a rise amount of a remaining capacity by an extended regeneration control is large in the pre-use segment and the downward slope segment, the target remaining capacity SOC* is set to a 'low-side remaining capacity Sd which is a sum of &#x394;Sd and &#x394;Ssmaller than the standard remaining capacity Sn.'

Control device for hybrid vehicle

An electric distribution box includes a circuit which is operable to perform the flowing, interruption and detection of electric current, and the circuit having distribution parts and a first bus bar which connects the distribution parts, a case body in which the circuit is contained, and an external input/output terminal portion which is detachably mounted on an outer surface of the case body, and is adapted to be connected to the first bus bar.

Electric distribution box

An arrangement structure of an electric junction box is provided, by which damage of the electric junction box in the event of a collision of a vehicle can be reduced and a plurality of electric wires can be easily connected to the electric junction box with good workability. The arrangement structure includes: a high voltage battery; a battery pack for receiving the battery, the battery pack being mounted on a vehicle; and an electric junction box arranged in the battery pack, the electric junction box being connected to the battery, wherein on the assumption that a collision takes place on the battery pack-mounting side of the vehicle, the electric junction box is arranged on the side of a wall of the battery pack, the wall being situated on the side opposite to the collision side of the vehicle.

Arrangement structure of electric junction box

Preventing a controller securely from effects of heat or noise of a relay and a high-tension circuit, a synthetic resin inner cover is arranged between a top cover and a bottom cover. A high-tension circuit is arranged between the top cover and inner cover. A control baseboard is provided at the bottom cover. The bottom cover is covered by the inner cover. Thereby, the control baseboard is prevented from being heated by the high-tension circuit by the inner cover. A conductive metallic shielding cover is arranged between the bottom cover having the control baseboard and the inner cover to cover the bottom cover including the control baseboard. Thereby, the control baseboard is prevented from noise of the high-tension circuit. The inner cover and the shielding cover having respectively a flange are fixed on a vehicle body by a bolt to overlap the both flanges.

High-tension connector box

An electric distribution box for containing a distribution parts includes a first case, a second case that is attached to the first case, and a female-female terminal that has holding portions for holding and electrically connecting mating terminals. A first recess portion is provided on one of the first and second cases, and receives a part of the female-female terminal. A second recess portion is provided on the other of the first and second cases, and receives a remaining part of the female-female terminal. An inserting hole for inserting one of the mating terminal to contact with the female-female terminal is formed in at least one of the first and second recess portions.

Positive electrode busbarandand negative electrode busbarandtoare provided. A plurality of positive electrode terminalsandfollowing to positive electrode busbar are disposed in one connector housing to constitute connectorsandand a plurality of negative electrode terminalsandtofollowing to negative electrode busbar are disposed in the other connector housing to constitute the connectorsandof negative electrode and they are applied to the junction block circuit structure A. The positive electrode busbarandand negative electrode busbarandtoare disposed in different layer intervening an insulating plate. Each positive electrode busbarand negative electrode busbaris connected to the total output part of battery circuit, the total output partandof inverter circuit and other output parts, the other output parts are provided with positive terminalsandand negative terminalsand. The total output partandare disposed in the center of the junction block. The invention makes connector miniaturize and simple.

A guide wall and a recessed portion for accommodating therein a female-female terminal are formed in a lower case, and in an intermediate plate, a through hole through which an electric connection portion which is in abutment with the guide wall is formed and a guide portion is provided at a lower edge portion of the through hole so formed so as to protrude therefrom so as to be brought into abutment with the electric connection portion, so that the electric connection portion is guided into the through hole. Thus, by inserting the intermediate plate between the upper case and the lower case so as to be held therebetween, the guide portion automatically corrects the bend of the electric connection portion.

Bus bar mounting structure

Preventing an electric connecting box having an upper cover and a lower cover, which can prevent the upper cover from approaching the lower cover over a limit when an electric component is mounted on the upper cover, the electric connecting boxis provided with an upper cover, a lower cover, a middle cover, a printed wire board, a wiring boardand a shield plat. The upper coveris mounted on the lower cover. The lower coverhas a first strutabutting on the shield plate. The first strutsupports the upper coverthrough the shield plateand the wiring board
