Embodiment Construction

[0030] Embodiment of pure electric vehicle power output control method

[0031] The pure electric vehicle power output control method generally includes the following steps:

[0032] (1) Obtain the corresponding maximum allowable output power value by looking up the table according to the current SOC information and temperature information of the power battery;

[0033] (2) Compare the actual demand power of the vehicle with the maximum allowable output power value of the power battery: if the actual demand power is greater than the maximum allowable output power value, drive the vehicle with the maximum allowable output power value; if the actual demand power is less than or equal to the maximum allowable output power value output power value, the vehicle is driven with the actual required power.

[0034] Each step is described in detail below.

[0035] First of all, the maximum allowable output power value is the maximum output power value at which the power battery can be...

Abstract

The invention relates to a power output control method and device as well as a power feedback control method and device. According to SOC and temperature of a power battery, maximum allowed output power value and maximum allowed charging power value can be obtained; and then the actual power of a vehicle is compared with the obtained maximum allowed power value of the power battery; and accordingto the comparison result, the power battery is correspondingly controlled. Therefore, the power output control method is power active control so that the optimal state of the vehicle power demand canbe guaranteed and the over-discharge and over-charge of the power battery can also be avoided to avoid the damage to the power battery; and the normal input or output of the power battery is guaranteed.

Description

technical field [0001] The invention relates to a power output control method and device, a power feedback control method and device, and belongs to the technical field of power control of pure electric vehicles. Background technique [0002] In recent years, new energy vehicles have maintained a good momentum of development, and OEMs have injected a lot of manpower and material resources into related technology research and development. With the batches of new energy buses and group vehicles being put into market operation, it also indicates that this new vitality is in the future. rise in the automotive industry. Accelerating the cultivation and development of energy-saving and new energy vehicles is not only an effective way to alleviate the pressure on energy and the environment, but also an urgent task to promote the sustainable development of the automotive industry. With the introduction of subsidies and preferential policies for new energy vehicles by the national m...
