Charging is started with charge voltage set to a first voltage value (lower than a normal charge voltage) by a charge voltage change means, the first voltage value being predetermined to ensure that secondary batteries constituting a parallel-arrangement battery pack are charged up to and maintained at a predetermined SOC lower than full charge (between 80 and 90% of full charge). When a charge current detection means detects that charge current has decreased to a predetermined value A 1, the charge voltage is set to a second voltage value (normal charge voltage) higher than the first voltage value by the charge voltage change means, the second voltage value being predetermined to enable the secondary batteries to be charged up to full charge. When a battery SOC detection means detects that at least one of the secondary batteries has reached full charge, charging is terminated.

Bi-directional, reverse blocking battery switch

Embodiments of the present invention relate to an improved package for a bi-directional and reverse blocking battery switch. According to one embodiment, two switches are oriented side-by-side, rather than end-to-end, in a die package. This configuration reduces the total switch resistance for a given die area, often reducing the resistance enough to avoid the use of backmetal in order to meet resistance specifications. Elimination of backmetal reduces the overall cost of the die package and removes the potential failure modes associated with the manufacture of backmetal. Embodiments of the present invention may also allow for more pin connections and an increased pin pitch. This results in redundant connections for higher current connections, thereby reducing electrical and thermal resistance and minimizing the costs of manufacture or implementation of the die package.

A system and method for determining whether an onboard estimation process, such as a recursive least squares regression process, can effectively calculate the state-of-charge of a battery. The method includes defining a current sample time and a previous sample time and measuring the battery current. The method then calculates a variation moving average of the measured current and an index of current change rate determined by averaging the absolute value of the current variation moving average using the measured current and calculated moving averages from the previous sample time. The method then determines if the current change index is greater than a predetermined threshold, and if so, the estimate of the battery state-of-charge resulting from the onboard estimation process is valid.

Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.
