Abstract

The invention relates to a device and a method for estimating generating capacity of a vehicle-mounted solar battery, belonging to the technical field of electric vehicle power supply. The device for estimating the generating capacity of the vehicle-mounted solar battery disclosed by the invention comprises a maximum power point tracking controller MPPT, an electric vehicle power battery system and an electric vehicle control unit VCU, wherein the electric vehicle power battery system comprises a power battery pack and a battery management system BMS which is connected with the power battery pack; the electric vehicle control unit VCU is connected with the battery management system BMS via a CAN (Controller Area Network) bus; the maximum power point tracking controller MPPT is connected with a to-be-estimated solar battery; and the control signal input end of the maximum power point tracking controller MPPT is connected with the electric vehicle control unit VCU. According to the device disclosed by the invention, the structure is reasonable, the estimation is accurate, and the solar generating capacity can be detected under the condition that the battery is off-line; and when enough generating capacity is detected, the electric vehicle control unit and the BMS are restarted and waken up.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supply, in particular to a device and method for estimating the power generation of a vehicle-mounted solar battery with reasonable structure, low energy consumption, accurate estimation, and the ability to effectively use the solar battery to provide power for the vehicle. Background technique [0002] With the development of electric vehicles, solar power generation is also applied to electric vehicles. Current technology can integrate solar panels into the roof material, and use solar energy to convert electricity to provide kinetic energy for electric vehicles. However, the amount of solar power generation is directly related to the environment. In the current environment, when the power generation capacity is smaller than the self-consumption of the battery management system and MPPT itself, it is uneconomical to start power generation. Therefore, it is necessary to start the p...
