Abstract: A vehicle central lock antitheft method and system includes a central lock system which is connected by radio with a remote controller for identity verification using rolling codes (S101, S102), wherein the central lock system chooses a security state (S103) and transmits the security state to an engine management system according to the verification result, the ignition IG status and the door switch status signal indicating opening or closing of the door (S104). The engine management system receives the security state transmitted by the central lock system and verifies the identity of the central lock system by code matching (S106); security identification between the engine management system and the central lock system is carried out by bidirectional encryption communication (S107). The engine management system then decides whether or not to lock the engine according to the result of the security identification.
Abstract: A nickel-hydrogen battery pack heat removal system for hybrid vehicle is provided. The system includes a battery box, a power battery pack (8), a battery support frame (9), a support bar (5), an air inlet (1), an air outlet (6) and a fan (7). Batteries in the power battery pack (8) are aligned in parallel in two layers one above the other in the battery support frame (9) of the battery box, and the support bar (5) and the battery support frame (9) are fixed on the upper and lower soleplates respectively of the battery box. The air inlet (1) is set at one end of the battery box, the air outlet (6) is set at the other end of the battery box, and the fan (7) is fitted at the air outlet (6). The system further includes conduction plates (2) in the shape of circular arcs, said conduction plates (2) being fitted on the opposing faces of the two upper and lower batteries which are closest to the air inlet (1).
