A fault-tolerant unit and a fault-tolerant method for through-silicon via (TSV) are provided. The fault-tolerant unit includes TSV structures TSV&#x2dc;TSVn, nodes N&#x2dc;N, nodes N&#x2dc;Nand a switching module. The TSV structure TSVi is connected between the node Nof the first chip and the node Nof the second chip, wherein 1&#x2266;i&#x2266;n. The switching module is connected between the nodes N&#x2dc;Nof the second chip and a test path of the second chip. In normal operation state, the switching module disconnects the test path and the nodes N&#x2dc;Nwhen the TSV structures TSV&#x2dc;TSVn are valid. The switching module connects the node Nto at least another one of the nodes N&#x2dc;Nwhen the TSV structure TSVi is faulty in the normal operation state. In test status, the switching module connects the test path to the nodes N&#x2dc;N.

Fault-tolerant unit and method for through-silicon via

An expert system manages a power grid wherein charging stations are connected to the power grid, with electric vehicles connected to the charging stations, whereby the expert system selectively backfills power from connected electric vehicles to the power grid through a grid tie inverter (if present) within the charging stations. In more traditional usage, the expert system allows for electric vehicle charging, coupled with user preferences as to charge time, charge cost, and charging station capabilities, without exceeding the power grid capacity at any point. A robust yet accurate state of charge (SOC) calculation method is also presented, whereby initially an open circuit voltage (OCV) based on sampled battery voltages and currents is calculated, and then the SOC is obtained based on a mapping between a previously measured reference OCV (ROCV) and SOC. The OCV-SOC calculation method accommodates likely any battery type with any current profile.
