摘要： PROBLEM TO BE SOLVED: To ensure insulation and enable data collection about each secondary battery even when high voltage battery is composed of serially-connected secondary batteries.SOLUTION: The battery system of the present invention comprises a plurality of battery modules that include a battery cell and a battery state estimating device for detecting and estimating the state of the battery cell connected in series-parallel. Each battery module has radio-communication antennas for communicating with each other in a one-to-one manner arranged on the upper surface and lower surface thereof. Setting apart the antennas on the upper and lower surface from each other can avoid communication failure caused by interference of signals transmitted from the communication antennas. The battery modules perform radio-transmission so that wiring that connects the battery modules is not necessary. As a result, short circuit due to failure is prevented, leading to improvement of reliability.

摘要： PROBLEM TO BE SOLVED: To intermittently transmits/receives radio signals to/from a communication target. SOLUTION: The electric power generated with a power generating circuit 151 is accumulated in a capacitor 152. When the accumulated electric power reaches a set level, a sensor body 120, a calculation circuit 130, a radio transmission circuit 111 and a radio reception circuit 112 are sequentially triggered only for a certain period. The sensing information detected with the sensor body 120 is processed with the calculation device 130. The result of the process is added with the information about the number of bites that can be received with the radio reception circuit 112. The added information is transmitted as sensor information to a radio host 20 from the radio transmission circuit 111. The radio reception circuit 112 that is triggered after the radio transmission circuit 111 is triggered receives control information signal 32 from the radio host 20, and the reception information is processed with the calculation device 130.

摘要： PROBLEM TO BE SOLVED: To evade generation of a general reset signal and to surely finish a CPU processing when the power supply is interrupted or cut off by monitoring a power cut-off previous announcement signal after reception of a manual or soft reset request signal. SOLUTION: When a power supplied from a power unit 2 is cut off, a reset circuit 19 transmits a manual or soft reset request signal M/S-GR-N to a CPU 31, an ASIC 33 and a communication controller 34 which need a general reset signal GR-N respectively via the logic circuits 15 and 16 and a pulse generation circuit 17. Even when the signal M/S-GR-N is generated right before the power supply is interrupted or cut off, the circuit 15 of the circuit 19 refers to a power cut-off previous announcement signal POP (or a power supply valid signal) to generate the signal GN-R. In such a circuit system, a CPU processing can be finished with no disturbance when the power supply is interrupted or cut off. Thus, emergency information is always protected.
