Abstract: A battery State of Health estimation method based on a standard sample and a dual-embedded decoupling includes the steps of extracting significant characteristic peaks of the standard sample, mechanism parameter calibration of the standard sample, and on-line State of Health estimation of the test battery. The battery State of Health estimation method expounds the dual coupling relationship between temperature and aging on the characteristic peak voltage of Incremental Capacity curve from the perspective of impedance characteristic mechanism analysis, and proposes a method eliminating the voltage deviation caused by the most temperature-sensitive charge transfer resistance based on the “standard sample” to realize the decoupling of the first layer. Further, when the Solid Electrolyte Interface film resistance affected by the aging and temperature coupling conforms to a linear relationship as a whole, the embedded decoupling can be realized by establishing the relation function between the linear relationship coefficient and temperature.

Abstract: An on-line State of Health estimation method of a battery in a wide temperature range based on “standardized temperature” includes: calculating battery Incremental Capacity curve of a battery, establishing a quantitative relationship between the voltage shift of the temperature-sensitive feature point and the temperature of a standard battery, standardized transformation of Incremental Capacity curves at different temperatures, establishing a quantitative relationship between the transformed height of the capacity-sensitive feature point and the State of Health based on a BOX-COX transformation. The BOX-COX transformation is expressed as y k ( λ ) = { y k λ - 1 λ λ ≠ 0 ln ⁢ ⁢ y k λ = 0 . An maximum likelihood function is used to calculate the optimal λ, and the transformed height of the capacity-sensitive feature point y can be acquired. The quantitative relationship between transformed height of the capacity-sensitive feature point and the State of Health is established to obtain the State of Health.

Abstract: An energy dynamic control method for the EPS with hybrid power supply and an energy dynamic control system. Control system collects real-time current of vehicle electric appliances except the steering motor and the super-capacitor and calculates target current of the steering motor according to real-time steering torque and vehicle speed, and determines state of the super-capacitor by comparing rated current of vehicle power supply and sum of the current of vehicle electric appliances and target current of the steering motor. When super-capacitor is in the charging state, charging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum charging current is limited based on SOC of the super-capacitor. When super-capacitor is in discharging state, discharging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum discharging current is limited based on SOC of super-capacitor.

Abstract: A continuously variable transmission with both equal-difference output and equal-ratio output includes an input mechanism, a hydraulic transmission mechanism, a planetary-gear-set convergence mechanism, an equal-difference output mechanism, an equal-ratio output mechanism, a clutch assembly, and a brake. The clutch assembly connects an output end of the input mechanism to an input end of the hydraulic transmission mechanism and the planetary-gear-set convergence mechanism and connects an output end of the hydraulic transmission mechanism to the planetary-gear-set convergence mechanism. The clutch assembly connects the planetary-gear-set convergence mechanism to the equal-difference output mechanism and the equal-ratio output mechanism. The clutch assembly connects the equal-ratio output mechanism to the equal-difference output mechanism. A continuously changing transmission ratio between the input mechanism and the equal-difference output mechanism/the equal-ratio output mechanism is provided by adjusting a displacement ratio of the hydraulic transmission mechanism and selectively controlling engagement of the clutch assembly and the brake.
