The utility model protection domain not only is confined to above-mentioned embodiment, and other people make the non-intrinsically safe improvement, all belongs within the protection domain of the present utility model.

The floating charge characteristic that the utility model is alleged: battery pack is the standby power supply of the vehicle-mounted straight-flow system of pure electric vehicle electric power.The floating charge line feature is that battery pack and floating machine power circuit are connected on the load circuit in parallel.Under normal running state, the charging unit that links to each other with dc bus except to the conventional load power supply, also provides floating current to battery pack, and this method of operation is called full floating charge working method, is called for short floating charging operation.Floating charge is the electric mode of a kind of confession (putting) of battery pack, system is parallel-connected to battery pack and floating machine power circuit on the load circuit, his voltage is constant substantially, only a little more than the terminal voltage of battery pack, by the floating machine power circuit a small amount of electric current of confession compensate the loss of battery pack local action, satisfy state and unlikely overcharging can often remain on charging.Therefore, battery pack can fluctuate up and down and discharges and recharges with the floating machine power line voltage, when the light and floating machine power line voltage of load is higher, battery pack is namely charged, when load during heavier or floating machine power supply interrupt, battery pack is then discharged, and shares part or all of load.Like this, battery pack just plays pressure stabilization function, and is in stand-by state.The floating charge power supply working method can be divided into partial floating and two kinds of full floating charges.When part-time (when floating machine is subjected under the simultaneous force effect to start rotation) carries out floating charge power supply, and part-time (during the floating machine stall) is called the partial floating working method by the independent working method of power supply of battery pack in addition, or full floating charge working method of weighed phase.If All Time then is called full floating charge working method by floating machine power circuit floating charge power supply in parallel with battery pack, or claim continuous floating charge work side

Formula.

With the battery pack that the floating charge working method is used, its life-span generally more full charge and discharge system person to grow, and the battery pack that can use less capacity instead replaces.

The simultaneous force that the utility model is alleged, in aerodynamics, Nonlinear Elliptic Partial Differential Equation theory and approximation method, by experiment and observe, flow phenomenon and mechanism are analyzed, and propose rational mechanical model, participate in Fig. 1, Fig. 2, Fig. 3, Fig. 4, this model is followed: the kinology aspect, follow mass conservation law; Newton's second law is followed in the dynamics aspect; Law of conservation of energy is followed in transformation of energy and transmission aspect.Thermomechanics the first and second laws are followed in the thermomechanics aspect.Corresponding equation of state of gas and viscosity are followed in the media property aspect, the Changing Pattern of thermal conductivity etc.The hollow wind wing passes in the air that travels separates air-flow, and referring to Fig. 1, portion of air flows through from hollow wind wing top, and another part flows through from the below.Flowing of air is invisible in daily life, but flowing of low speed flow has larger similarity with current, the daily experience of life is told us, when current are crossed the riverbed with a metastable traffic flow, slow at the local flow velocity that river surface is wider, the local flow velocity narrower in the riverbed is very fast, and the air-flow and the flowing water in the river that flow through the hollow wind wing are similar.

Because the hollow wind wing is asymmetric, the curvature of its front end is larger, the curvature of rear end is less, the air-flow that flows through hollow wind wing upper surface just is similar to the flowing water in narrower place, flow velocity is very fast, and the air-flow that flows through below the hollow wind wing is just in time opposite, be similar to the widely flowing water of side, flow velocity is slow than the air-flow of upper surface, according to hydromechanical basic principle, the slow atmospheric pressure that flows is larger, and the fast barometric pressure that flows is less, and the pressure of the hollow like this wind wing lower surface just pressure than upper surface is high, in other words, be exactly that the atmosphere pressure that puts on hollow wind wing lower surface (direction make progress Fig. 1) is larger than the pressure that puts on hollow wind wing upper surface (the downward Fig. 1 of direction), the pressure difference of the two just formed the hollow wind wing when axle horizontal before the wind wheel wing produce lift.Fig. 1, the hollow wind wing is opposite with above-mentioned principle behind axle horizontal, produces decline power, participates in Fig. 2.

The hollow wind wing produces the reason of lift and decline power, in simple terms, electric vehicle to overtake faster, the aerodynamic force that the hollow wind wing produces is also just larger, when lift (shown in Figure 1) and decline power (shown in Figure 2) greater than generator field power when (being called gravity), just can synchronous generator, when lift (shown in Figure 1) and decline power (shown in Figure 2) less than generator field power when (being called gravity), the hollow wind wing when axle is vertical, participate in Fig. 3, by the forward action power of electric vehicle, produce thrust.

When axle was vertical, the lower hollow wind wing was referring to Fig. 4, and the symmetrical air-flow in certain tilt angle (being called the angle of attack or the angle of attack) is separated and flow through and produce a vortex system 10 at hollow wind wing afterbody, (being called Karman vortex street), will produce the backflow pulse, go into Hui Li, referring to Fig. 4.

Physical law according to above-mentioned aspect, pure electric vehicle is resistance zuli to overtake, the backward active force air-flow that air produces, floating stressed synchronously through hollow wind wing Fig. 1, Fig. 2, Fig. 3, Fig. 4, be a new subject, i.e. synchronous mechanics, it is an aerodynamic branch, it mainly studies floating object, is making floating mechanical characteristic in the relative movement situation with gas, gas flow rule and physics, the chemical change of following generation.It is the new subject that development is grown up on the hydromechanical basis.Refer to that floating machine is installed in the anterior air intake position of pure electric vehicle, utilize the synchronous mechanics of generation that travels to be converted to aerodynamic force and can generate electricity, generally account for the anterior air intake of pure electric vehicle position≤75%.

Implementation of the present utility model is exemplified below:

At first, with floating machine, be installed in the anterior air intake position of pure electric vehicle, when approximately travelling the above speed per hour of 40km/h and wind speed 19-20m/s by pure electric vehicle, four hollow wind wings, front hollow wind wing A, upper hollow wind wing B, rear hollow wind wing C, lower hollow wind wing D are subjected under the simultaneous force effect to start and rotarily drive generator and generate electricity, and load and the battery pack floating charge work of pure electric vehicle are provided.
