A method, an apparatus and a device for identifying battery parameters, and a storage medium are provided. The method includes: determining to-be-identified parameters of the battery and determining an initial population; performing a screening step with the initial population as a current population: for at least part of individuals in the current population, updating positions of the individuals in the current population through local optimization and generating corresponding first individuals, and updating the positions of the individuals in the current population through Levy flight and generating corresponding second individuals; selecting an optimal individual according to fitness of the individuals in the current population and the corresponding first individuals and the corresponding second individuals, as an individual in the next generation population; repeating the above screening step until a termination condition is met, to obtain a final population; and determining the to-be-identified parameters included in the optimal individual in the final population as the parameters of the battery. With the method, the apparatus and the device for identifying battery parameters and the storage medium, the speed of parameter identification is effectively improved.

A rocker arm mechanism of an engine, a system and a method for two-stroke engine brake are provided. The rocker arm mechanism includes a first rocker arm, a second rocker arm and a connection mechanism. One end of the first rocker arm and one end of the second rocker arm is rotatably connected to a shaft, the other end of the first rocker arm is close to a valve of the engine, while the other end of the second rocker arm is close to a cam. The connection mechanism includes a connecting piston and a linkage mechanism. The connecting piston is disposed in the first rocker arm or the second rocker arm, the linkage mechanism is rotatably connected to one end of the connecting piston. The rocker arm mechanism may be used for engine cylinder deactivation and engine brake.
