Description
Technical Field
The invention belongs to the technical field of drive control of hybrid vehicles, and particularly relates to a power control method based on a hybrid power supply for hybrid power.
Background
The diesel engine for the traditional armored vehicle is used as power, and can meet most of use requirements of the armored vehicle. But the armored vehicle enters into ventilation poor areas such as air holes and the like, and the vehicle can realize zero emission so as to prevent the air quality from being influenced by the huge emission and the lower emission quality of the armored vehicle, cause CO poisoning and the like. Moreover, the armored vehicle has higher stealth requirements sometimes, and the armored vehicle can greatly reduce the infrared and noise radiation of the vehicle by adopting pure electric driving, thereby being beneficial to avoiding infrared detection and noise search. These all place a need for the armored vehicle to be electrically driven. However, in view of the fact that the energy storage density of the existing battery is low and far cannot meet the requirement of long-distance combat of armored vehicles, the hybrid power scheme is a feasible scheme. The electric power-driven armored vehicle meets the requirements of long-time and high power of the armored vehicle and also meets the requirements of less pure electric driving.
Most of the existing Hybrid Electric Vehicles (HEVs) adopt a storage battery as the vehicle-mounted energy storage source, but the capacity of sudden high power of the HEV stored by the storage battery is limited due to the lower specific power of the storage battery when the HEV is accelerated, climbed or regeneratively braked. The battery alone as an energy storage source for an HEV is more problematic, most notably the limited ability of the battery to capture regenerative braking energy or provide sudden high power during short duration events such as acceleration, hill climbing, braking, etc. This high power limitation reduces the efficiency of the hybrid system design and does not meet the short term power requirements of the HEV. If this power limitation is remedied by increasing the number of energy storage sources, it will tend to increase the cost and weight of the HEV. Meanwhile, the service life of the storage battery is also affected by large-current charging and discharging, and particularly when regenerative braking energy is recovered, the cycle service life of the storage battery is greatly shortened due to low charging efficiency of the storage battery, especially large-current charging.
The super capacitor has the advantage of high specific power, but the super capacitor is difficult to independently become a driving energy source of the HEV due to the defect of low energy density of the super capacitor, and the super capacitor is used as an auxiliary and is combined with a storage battery to be used as a power source of the HEV, so that the super capacitor is a better path for solving the problem of a hybrid power source. The super capacitor and the storage battery can be combined to give full play to the advantages of the super capacitor and the storage battery, the limited output instantaneous power capacity of the storage battery is made up during acceleration and climbing, the braking energy is recovered quickly, the fuel efficiency is improved under the urban working condition of frequent start-stop, the working efficiency of the energy storage system is improved, the service life of the storage battery is prolonged, the number of series-parallel batteries is not required to be increased for meeting the energy and power requirements at the same time, and the waste of system configuration is avoided. The composite power supply composed of the storage battery and the super capacitor can improve the energy utilization rate of the system and effectively improve the cycle service life of the storage battery.
