The invention relates to the technical field of automobile control, in particular to an energy management system and management method for increasing the driving range. The energy management system comprises a battery temperature acquisition module used for acquiring the current temperature of a battery; a temperature judgment module used for judging whether the current battery is in a braking energy recovery limited state or not according to the obtained battery temperature; an energy judgment module used for comparing the braking energy recovery power during deceleration with the current battery recoverable power and judging whether the braking energy recovery power is greater than the battery recoverable power or not; a heat management module used for adjusting the battery temperature; and a control module used for controlling the heat management module to adjust the battery temperature when the battery is in the limited state and the braking energy recovery power is larger than the battery recoverable power. The management system is simple in structure and convenient to operate, braking energy is well recycled and distributed under the condition that the battery is in a limited state, energy waste is avoided, and the driving range of the battery is prolonged.
