Abstract: An electrical system having a master node, at least one slave node and a bus linked to both of the master node and the slave node is illustrated. The master node check whether a reception register of the slave node does not receives a new data for a first time period, and resets the slave node while the reception register of the slave node does not receives the new data for the first time period; and the slave node checks whether the reception register of the slave node does not receives the new data for a second time period, and resets the slave node itself while the reception register of the slave node does not receives the new data for the second time period. Therefore, the communication stability of the electrical system can be enhanced.

Abstract: A baffle structure for heat dissipation, mounted on an electric vehicle on top of which a battery pack is mounted, includes a base, a plurality of baffle fins and a mask. The base is connected to the battery pack. The baffle fins are disposed on the base. The baffle fins each have a first end and a second end. The mask covers the baffle fins. The mask includes at least an air inlet and at least an air outlet which correspond in position to the first and second ends, respectively. The baffle structure guides hot air out, takes up no space inside the electric vehicle, dispenses with a need to be connected to any external cooling system, and saves electrical power supplied by the battery pack.
