Abstract:
A battery module comprises a battery pack including a plurality of cells and a plurality of connectors to electrically connect adjacent cells respectively; a case housing the battery pack; and a sampling unit fixed to the case and including: a BIC module fixed onto the case; a wiring trough fixed onto the case; a signal sampling terminal; and a sampling wire disposed within the wiring trough and having a first end electrically connected to the BIC module and a second end electrically connected to the signal sampling terminal.
Abstract:
Disclosed are a carrier communication method based on electric automobile charging/discharging, comprising the following steps: S1: after being powered up and started, an electric automobile detecting whether a carrier signal from a peripheral device is received through an interface wire harness and whether the carrier signal is correct; S2: when detecting the carrier signal and detecting that the carrier signal is correct, the electric automobile receiving the carrier signal through the interface wire harness; and S3: the electric automobile performing coupling and filtering on the received carrier signal to convert the carrier signal into a standard carrier signal, and demodulating the standard carrier signal into a digital signal to obtain information of the peripheral device. The method, on the basis of not increasing the number of wire harness, may implement data transmission and sharing between an automobile and ECU modules of a peripheral device, and carrier communication with other signal lines as communication media at the same time, so as to avoid construction and investment of a new communication network, and reduce manufacturing cost and maintenance difficulty. Further disclosed are a carrier communication system and a carrier apparatus based on electric automobile charging/discharging.
Abstract:
A hybrid power driving system is provided, comprising an engine; a first motor; a first reducing mechanism, a second clutch, a first wheels group, a second motor, a second wheels group, a second reducing mechanism, an energy storage device, a clutch, an engine controller, and a motor controller. The motor controller may be configured to: start or stop at least one of the first motor or the second motor; and control the clutch controller and the engine controller according to a running mode of the hybrid power driving system.

Abstract:
An oil pump is provided. The oil pump comprises a shell, a rotor mounting part disposed at an end of the shell, and a rotor mechanism disposed on the rotor mounting part. The shell has an inlet and an outlet and defines a low-pressure oil chamber and a high-pressure oil chamber therein. The high-pressure oil chamber and the low-pressure oil chamber are located at the same side of a periphery of the rotor mounting part. An engine cover comprising the oil pump and an engine comprising the engine cover are also provided.
