Abstract

The invention discloses a power output method and a power output device for a battery. The power output method for the battery comprises the following steps of acquiring the target output power of the battery; calculating the permissible output power of the battery; judging whether the permissible output power is higher than or equal to the target output power or not; if the permissible output power is determined to be higher than or equal to the target output power, performing power output according to the target output power; if the permissible output power is determined to be lower than the target output power, reacquiring the target output power. According to the method and the device, the problem that the service life of the battery is shortened by the power output of the battery under a dynamic load in the prior art is solved, and the effect of prolonging the service life of the battery is achieved.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery power output method and device. Background technique [0002] With increasing awareness of energy conservation and environmental protection, more and more vehicles such as vehicles use batteries as power sources, for example, fuel cells are used as vehicle power sources. As a new type of green power source, the battery engine has gradually become the focus of vehicle engine research due to its high efficiency and low emissions. In order to ensure the durability of the power source, the service life of the battery is an urgent problem to be solved. Power output under load is often a significant contributor to battery life degradation. [0003] Take the fuel cell as an example. At present, the fuel cell generates electric energy to directly drive the motor through the control of DCDC, and generates torque to drive the car. In this process, under the condition of fuel ce...
