Highlighting for the energy and environmental problem, is explored and is paid close attention to extensively using electric power as clean energy resource.Especially urge in recent years
Raw electric automobile and field of hybrid electric vehicles.
Comparatively speaking, the real-time display of the energy content of battery, the oil mass similar to orthodox car shows, with important left and right.
Especially in the starting stage of current charging network development, the accurate display of electricity seems even more important.
The display mode of electricity has various, and one kind is shown as parameter using voltage, and this display mode is progressively
It is eliminated, because electrokinetic cell its voltage difference under different loads, away from very big, is carried out voltage as parameter to electricity
Display is particularly inaccurate.
Another way is that electric energy is measured, that is, accumulative, the injection rate of calculating energy is integrated to electric current
And consumption, in this, as the foundation that energy shows.
However, the essence that electricity shows not is to be shown electric energy exactly, but the person of being desirable for is by the electricity
, used as reference, anticipation vehicle can be with the mileage number of actual travel for amount parameter.But, there is problems with the program：
1st, different people estimates mode difference (experience is different) to electricity, and same display data can show that gap is larger
Conclusion (first thinks that 50 kilometers can be travelled, and second thinks that 20 kilometers can only be travelled).
2nd, same electricity, for different users, the mileage of traveling is also different, this operating habit with user
Relevant, such as first is liked stepping on the gas, often anxious to step on the gas and brake, and the anxious deceleration that touches on the brake all is accustomed to before crossing；Second is then different,
Accelerator and brake is all very gentle.For electric automobile, the difference of above first and second operating habit causes electricity to be driven by second and goes
The distance sailed can be bigger than first.
