摘要： Disclosed is an optimized battery charging method based on thermodynamic information of a battery. Thermodynamic information on a material structure of a battery, for instance, entropy of the battery is extracted. Boundary points at which state transitions of the battery material are determined using the thermodynamic information extracted. Phases of the battery are identified based on the boundary points determined. The most appropriate charging patterns adapted to each of the phases identified are determined. A charging algorithm for charging the battery can be constructed by combining the most appropriate charging patterns determined. This charging algorithm is applied to the charging of the battery.

摘要： The present application provides a collecting module of a lead-acid battery and new lead-acid battery and the winding displacement is simpler when collecting the status parameters of the lead-acid battery by disposing the collecting module in the housing of the lead-acid battery and the security is improved when detecting. At the same time, the data storing unit of the collecting module not only stores the collected raw data of the battery at the time of shipment from the factory, but also stores the collected status parameters of the battery in use, which facilitates the subsequent comparison between the raw data and the status parameters, a more accurate determining on the health status of the lead-acid battery and acquisition for the optimal maintenance of the lead-acid. Further, the internal temperature of the lead-acid battery can be more accurately collected by disposing the internal temperature acquisition unit in the lead-acid battery, and if the overheating of the battery occurs, it can be notified in time and dealt with, thus the scrapping of the battery is decreased and the power supply quality for the base station is improved.

摘要： A handheld analyte meter, such as a blood glucose meter, has a measurement module, a rechargeable battery and a charging control to select a maximum charging current to regulate self-heating during recharging that can interfere with analyte tests. Self-heating by the meter can bias temperature measurements made inside the meter that are used to determine whether the temperature is acceptable for testing. Prior to beginning a charging session, the charging control selects the maximum charging current that does not change during the charging session based capacity of a charging source along with a first temperature measured near the battery that is compared with a first temperature range. By selecting the maximum charging current in this manner, the risk of the measurement module preventing a test under high lock-out conditions and the risk of the measurement module allowing a test when low lock-out conditions that are masked is reduced.

摘要： A charging system includes a first battery pack having a first capacity, a second battery pack having a second capacity and a charger for charging the first battery pack and the second battery pack. When the first battery pack is charged by the charger at a predetermined charging current I, a first charging time in which the first battery pack reaches a predetermined temperature T is set as a predetermined time t. When the second battery pack is charged by the charger at the predetermined charging current I, and when a second charging time of the second battery pack reaches the predetermined time t, the second battery pack is charged at a lower charging current. The first capacity is less than the second capacity.

摘要： A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate in near real time for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs.
