Title: Lead acid battery
Inventor: FUJIMOTO TADAO
IPC: H01M2/12
Filed: 2019-07-22
Abstract: To inhibit pole column corrosion.SOLUTION: The corrosion of a pole 45 that protrudes downward from the lower surface of a bushing 41 is suppressed by setting the level of an electrolyte U filled in a battery case 20 to be higher than the lower surface of the bushing 41 that penetrates a lid member 50 that seals the battery case 20, and immersing the pole 45 in the electrolyte U. In this method, since the pole 45 protruding downward from the lower surface of the bushing 41 is immersed in the electrolyte U, the pole 45 is difficult to touch the air. Therefore, corrosion of the pole 45 can be suppressed.SELECTED DRAWING: Figure 3

IPC: H04L47/27
Filed: 2019-09-05
Abstract: To perform update processing without affecting vehicle operations in an on-vehicle communication device and a communication method.SOLUTION: A gateway 18 distributes divided data for update acquired by a wireless communication module 16 to an on-vehicle device 12 via a bus 22. At the time of distribution, a communication line load transmission interval determination unit 50 determines a transmission interval from the load of the bus 22. A device load transmission interval determination unit 52 determines a transmission interval from at least one processing load of the on-vehicle device 12 and the gateway 18. A distribution control unit 48 compares the transmission interval determined by the communication line load transmission interval determination unit 50 with the transmission interval determined by the device load transmission interval determination unit 52, and performs control so that the divided data for update is delivered at a transmission interval equal to or longer than the longer interval. Therefore, since the transmission interval is determined based on not only the load of the bus 22 but also the processing load of the on-vehicle device 12 or the gateway 18, transmission delay of control data required for the running of a vehicle 24 can be reduced by the distribution of the divided data for update.SELECTED DRAWING: Figure 5
