    摘要: An electronic system, or its battery thermal management system, determines a thermal state of a battery used in the electronic system. A temperature at a position proximate the battery's cell is sensed during operation of the electronic system to produce a sensed value. Additionally, a temperature offset value is determined based on an aging factor for the battery. The sensed value is then adjusted based on the offset value to produce an adjusted value representative of the thermal state of the battery. According to one embodiment, a relationship between temperature offset value and battery aging factor is prestored in a memory of the electronic system. In such a case, the offset value may be retrieved from memory periodically or in response to a trigger event based on a determined aging factor. According to another embodiment, the offset value may be computed in real time based on a determined aging factor.

    摘要: Battery cells may be monitored and a historical profile of the battery generated. The historical profile may be used to analyze a state-of-health of the battery cell. For example, the historical profile may be used to determine when a battery cell has developed an internal short that creates a safety hazard. The historical profile may include a count of the number of times the battery cell was out of balance and a count of the number of Coulombs the battery cell was out of balance. The number of Coulombs may be counted for a window of time. When the number of Coulombs exceeds a Coulomb threshold, a state-of-health flag may be set for the battery cell. The Coulomb threshold may be adjusted based, in part, on the counted number of times the battery cell is out of balance.

    摘要: A system for estimating the state of health (SOH) of a battery of an electric vehicle includes a charger recognition unit, a discharge instruction unit, and an SOH estimator. The charge recognition unit generates a charge recognition signal based on a charge state of the battery. The discharge instruction unit receives the charge recognition signal when the battery reaches at least one predetermined charge voltage value, temporarily stops charging of the battery, and discharges the battery to a certain level. Discharge is performed by operating at least one function of the electric vehicle. The SOH estimator estimates the SOH of the battery based on a voltage change measured during discharging of the battery based on the at least one predetermined current value.

    摘要: A battery characteristic determining device includes a control module and a processing module. The control module outputs a control signal when a battery module is in a charging state and an SOC (state of charge; of the battery module reaches a predetermined target value, so as to result in change of a current of the battery module to a predetermined test value for a predetermined test time period. The predetermined test value is such that the change of the current causes a voltage of the battery module to decrease in the predetermined test time period. The processing module obtains a voltage variation of the battery module in the predetermined test time period, and a C rate of the battery module with reference to the voltage variation.
