Publication number: 20150077057Abstract: An automated charge preparation method periodically determines critical parameters for the set of relevant operating conditions, determines whether fast charging is possible, applies fast charging when possible, otherwise applies a dynamically scaled charging rate that is optimized based upon current critical parameters (while optionally heating the individual battery cells as long as fast charging is not available) to reduce/eliminate a risk of lithium-plating.Type: ApplicationFiled: November 21, 2014Publication date: March 19, 2015Inventors: Kurt R.

Publication number: 20150077060Abstract: In an equalization device for equalizing voltages of battery cells connected in series, each battery cell is provided with an equalization switch and a level shift section. The level shift section includes at least one level shift circuit. Each level shift circuit operates on a power supply voltage supplied from a series circuit of a predetermined number of adjacent battery cells. The level shift circuits are arranged so that potentials of the power supply voltages are different from each other in sequence. In the level shift section, a first level shift circuit outputs a pair of drive voltages by level-shifting a pair of control signals inputted from a second level shift circuit adjacent to the first level shift circuit, and a last level shift circuit outputs the pair of drive voltages as a control voltage for a corresponding equalization switch.Type: ApplicationFiled: September 5, 2014Publication date: March 19, 2015Inventors: Shouichi OKUDA, Ryotaro MIURA

Publication number: 20150077062Abstract: A battery management method and apparatus. In one embodiment of the method, a source current is divided into Ic and Icr. Ic is transmitted to and charges a battery. A first voltage is generated that is related to Icr. The first voltage is converted into a first digital signal. A processing unit receives and processes the first digital signal in accordance with instructions stored in a memory. The transmission of Ic to the battery is interrupted in response to the processing unit processing the first digital signal. Current provided by the battery is divided into Idc and Idcr. Idc is transmitted to a device. A second voltage is generated that is related to Idcr. The second voltage is converted into a second digital signal. The processing unit receives and processes the second digital signal in accordance with instructions stored in the memory. The transmission of Idc to the battery is interrupted in response to the processing unit processing the second digital signal.Type: ApplicationFiled: November 25, 2014Publication date: March 19, 2015Inventors: Tetsuo Sato, Tsutomu Kawano, Koji Kashimoto, Takao Hidaka, Tsuyoshi Otal, Ryoji Kato

Publication number: 20150077063Abstract: A power control device includes a relay switch, a controller, a sensor and a battery controller. The relay switch is configured to turn electricity on and off between a battery for supplying a load with electric power and the load. The controller predicts load power characteristics indicating characteristics of power consumed by the load over time, and predicts, based on the predicted load power characteristics, charge/discharge power characteristics indicating characteristics of charge/discharge power of the battery over time. The sensor detects voltage between the terminals of the battery. The controller specify a voltage detection period from the charge/discharge power characteristics that was predicted, over which the charge/discharge power of the battery is equal to or less than a prescribed power over a prescribed period. The battery controller turns off the relay switch and detects the voltage between the battery terminals during the voltage detection period.Type: ApplicationFiled: March 26, 2013Publication date: March 19, 2015Inventor: Yukari Tsukamoto
