A device for monitoring the function of an engine is powered by heat from the engine or other sources other than a conventional, external direct electrical power supply, which may create sparks and/or be unavailable. The device monitors one or more of heat, vibration, or other parameters and can detect certain problems with engine function. The device is particularly suited for remote engine monitoring, and can store and/or display data concerning monitored engine characteristics, and/or directly or indirectly send such data to a location removed from the engine.

An example operation may include one or more of connecting, by a battery analytics server, to a blockchain network that includes a plurality of charging station nodes, acquiring, by the battery analytics server, a current battery data from a charging station node of the plurality of the charging station nodes, the current battery data includes a battery identification (ID), storing, by the battery analytics server, the current battery data with a timestamp onto a blockchain ledger, comparing, by the battery analytics server, the current battery data against a pre-stored battery data based on the battery ID, and in response to a match, issuing, by the battery analytics server, a certification for a battery to be released from the charging station node of the plurality of the charging station nodes to a user.

A method and system for bidirectional data, power transmission, electrical/electronic fault isolation, and system recovery is shown and described. An exemplary embodiment includes a DC power source, a main power controller (“MPC”) with a MPC microprocessor and an MPC power switcher driver and fault switching control circuit, and a plurality of Nodes connected to the DC power source through conductors that allow both power to be supplied and bidirectional data transfer between a data receiver and the plurality of Nodes. The fault switching control circuit can provide for short detection and isolation (or other fault detection and isolation) without the direct involvement of the MPC microcontroller. The combined use of the conductors for power, data transmission, and fault detection and isolation offers significant advantages over the prior art in terms of weight reduction, system modularity, and complexity, as well as system protection and survivability.
