  • Patent number: 9810725
    Abstract: A method and device of charging a battery is provided. A charging device transmits a charging initiation request including a charging identifier for identifying a user to an electric meter and receives a charging initiation response from the electricity meter. The charging device performs charging by connecting the charging station with the battery after receiving the charging initiation response. The charging device receives charging information indicating billing information according to the charging of the battery from the electricity meter.

  • Patent number: 8886490
    Abstract: A crash detection apparatus includes a crash detection unit and first, second, and third acceleration sensors which are installed at different positions of the object whose crash is to be detected. The crash detection unit calculates expectation acceleration of the third acceleration sensor based on measurement information obtained by the first acceleration sensor and the second acceleration sensor, compares the expectation acceleration with a measured acceleration measured by the third acceleration sensor, and detects whether a shape of the object has been deformed or not.

  • Patent number: 8582269
    Abstract: An overcurrent protection apparatus for a secondary battery includes a main relay, an auxiliary relay connected in parallel with the main relay, a current limiting resistor connected in series with the auxiliary relay and a controller for detecting an overcurrent and protect the battery module. The controller turns on the main relay and turns off the auxiliary relay in a normal state where the battery module is recharged by the generator. When the overcurrent is detected, the controller turns on the auxiliary relay and turn off the main relay so that a limited current flows through the current limiting resistor.
