Embodiment Construction
[0033] figure 1 It is a general structural block diagram of a control device for a power follower and a power battery of an electric vehicle according to an embodiment of the present invention. Such as figure 1 As shown, the control device for a power follower and a power battery of an electric vehicle may include a power battery 1 , a power follower 2 , a controller 3 and an activation device 4 . The power battery 1 is used to output electric power to drive the traction motor 5 of the electric vehicle, and then drive the wheels 6 of the electric vehicle to rotate. The power follower 2 includes an engine 21 and a generator 22 for outputting electric power to drive the traction motor 5 and / or charge the power battery 1 . The engine 21 is connected with the generator 22, so that the generator 22 is driven to rotate to generate electricity when the engine 21 works. The engine 21 can use gasoline, diesel oil, natural gas and other energy sources. The generator 22 is connected w...

Disclosed are a power follower for an electric vehicle, and a control apparatus and method for a power battery, which belong to the technical field of electric vehicles. The apparatus comprises a power battery (1), a power follower (2), a controller (3) and an activation apparatus (4). The controller (3) is used to control a driving mode of the power battery (1) and the power follower (2). The controller (3) is configured to: select, when the remaining electric quantity of the power battery (1) is not greater than a first predetermined value, a second driving mode until the remaining electric quantity of the power battery (1) rises to a second predetermined value; select, when the remaining electric quantity of the power battery (1) is not less than the second predetermined value, a first driving mode until the remaining electric quantity of the power battery (1) is not greater than the first predetermined value; and alternately switch between the first driving mode and the second driving mode. The activation apparatus (4) is used to manually control the numerical value of the second predetermined value according to the requirement of a driver. The control apparatus can reduce oil consumption, prolong battery life and improve energy-saving performance.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control device and method for a power follower and a power battery of an electric vehicle. Background technique [0002] At present, the fuel consumption and emission requirements of vehicles are becoming more and more stringent. There have been extended-range electric vehicles on the market to reduce vehicle fuel consumption and reduce vehicle emissions. The energy supply of this extended-range electric vehicle is mainly based on power batteries. , the power battery required is large in capacity and heavy in weight. The power follower is used as an auxiliary energy source. When the remaining power of the power battery soc ("soc" described in this article is the abbreviation of "State of Charge", indicating the state of charge, that is, the state of charge of the battery) is less than a certain value, the power follower Charge the power battery. The engine in the po...
