Данное техническое решение направлено на расширение арсенала технических средств определенного назначения, а в качестве технического результата, достигаемого заявленным решением, является реализация заявленной полезной моделью указанного назначения, а именно объединение устройства преобразования и распределения электроэнергии с солнечных панелей с электрической системой любого транспортного средства с целью автономного питания электрических систем и зарядки штатных батарей. При этом предложенный алгоритм оптимальным образом перераспределяет энергию, полученную от солнца, в электрические системы транспортного средства, в результате чего снижается расход потребления топлива на автомобилях с двигателем внутреннего сгорания, увеличивается запас хода на электротяге у электротранспорта или транспортных средств с гибридной силовой установкой, происходит заряд штатных аккумуляторов во время стоянки, что приводит к уменьшению выбросов вредных веществ в городах и снижению нагрузки на инфраструктуру. Данный технический результат достигается благодаря устройству преобразования и распределения электроэнергии с солнечных панелей, которое объединяется с электрической системой любого транспортного средства, имеющего низковольтную бортовую систему (1) (см. фиг. 1-4).

A method and system for use with a vehicle battery pack having a number of individual battery cells, where the method estimates, extrapolates or otherwise determines individual cell resistances. According to an exemplary embodiment, the method and system use a voltage and temperature reading for each of the individual battery cells, as well as a voltage and current reading for the overall battery pack to determine one or more cell resistance values, such as a minimum and maximum cell resistance for the battery pack. This approach relies upon temperature deviations in the battery pack to make assumptions or estimates regarding individual battery cell resistances. By having individual cell resistance values—instead of using an overall pack resistance value and building in a buffer to account for cell variations—better and more accurate cell-level data can be obtained that, in turn, can improve charging, discharging, cell balancing and/or other battery-related processes.

System and method for energy management in an electric vehicle

Номер: US20130138279A1
Автор: Augusto Espinel Porras, Irene Michelle Berry, Paul Robert Gemin, Robert Dean King, Ruijie Shi
Принадлежит: General Electric Co

A vehicular energy management system (EMS) determines a net total power from a traction drive load, an auxiliary device load, and a regenerative power. If the net total power is a net supply power, the EMS causes regenerative power to be provided to a power source and energy source in a controlled manner to initially charge the power source to a desired state-of-charge (SOC) and then subsequently charge the energy source. If the net total power comprises a net power load, the EMS causes power to be drawn from the power source and the energy source, with a split of the power being drawn from the power source and the energy source being based on a magnitude of the net power load. The EMS adjusts/maintains the SOC set-point of the power source and the DC link voltage based on vehicle speed and relative altitude of travel of the vehicle.
