| 20090001934 | BATTERY TESTING APPARATUS - A battery testing apparatus includes a charge circuit, a discharge circuit, a computer, and a control circuit. The charge circuit is coupled to a direct current (DC) adapter, the DC adapter charges a battery through the charge circuit. The discharge circuit is coupled to the battery and configured to discharge the battery. The computer records charge/discharge time and charge/discharge cycles of the battery, and calculates capacity and cycle life of the battery according to the time and cycles of charge and discharge. The control circuit has an input terminal coupled to the computer, and a plurality of output terminals respectively coupled to the charge circuit and the discharge circuit, the control circuit controls the charge and discharge circuits charging and discharging the battery. | 01-01-2009 |
| 20090033284 | Charging device with battery capacity analysis function - The present invention provides a charging device with battery capacity analysis function, wherein a charging device includes a control unit, a computing unit, a display unit, a charging unit and a discharging unit. When the charging unit is connected to and charging a battery, the control unit determines whether the power of the battery is fully charged or not, and after the battery is fully charged, then the charging unit stops charging, and at the same time the discharging unit implements discharging of the battery. Moreover, the control unit controls stopping of electric discharge after the battery power is exhausted, which enables the computing unit to determine and calculate actual effective capacity of the battery, and enables the display unit to display the calculated capacity data, after which fully charging of the battery continues, thereby enabling the charging device to achieve battery capacity analysis and charging effectiveness. | 02-05-2009 |
| 20120105007 | LITHIUM ION BATTERIES WITH SUPPLEMENTAL LITHIUM - Supplemental lithium can be used to stabilize lithium ion batteries with lithium rich metal oxides as the positive electrode active material. Dramatic improvements in the specific capacity at long cycling have been obtained. The supplemental lithium can be provided with the negative electrode, or alternatively as a sacrificial material that is subsequently driven into the negative electrode active material. The supplemental lithium can be provided to the negative electrode active material prior to assembly of the battery using electrochemical deposition. The positive electrode active materials can comprise a layered-layered structure comprising manganese as well as nickel and/or cobalt. | 05-03-2012 |
| 20120249076 | ELECTRIC ENERGY STORE HAVING AN INTEGRATED DEEP DISCHARGE DEVICE - An electric energy storage device has a housing, a positive pole and a negative pole, and a deep discharge device integrated in the housing. The device further has a discharge load and it is configured such that the two poles can be electrically connected by way of the discharge load. There is enabled targeted and controlled deep discharging of the energy storage device and improved operating reliability. | 10-04-2012 |
| 20130257380 | SEMICONDUCTOR DEVICE FOR BATTERY CONTROL AND BATTERY PACK - A semiconductor device for battery control is provided with a control circuit capable of controlling turning on/off of a charging transistor provided in a charging path of a battery, a CPU capable of controlling charging of the battery via the control circuit, and a deep discharge detection circuit capable of detecting a deeply discharged state of the battery. The semiconductor device is also provided with a switch circuit which, when a deeply discharged state of the battery is detected by the deep discharge detection circuit, preferentially sends the detection result to the control circuit and, thereby, forcibly turns off the charging transistor regardless of charging control by the CPU. When a deeply discharged state of the battery is detected, the charging path of the battery is shut off to prohibit subsequent charging regardless of charging control by the CPU. | 10-03-2013 |
| 20140152265 | METHOD FOR MAINTAINING THE PERFORMANCE LEVEL OF AN ELECTROCHEMICAL CELL - A method of maintaining the performance level of an electrochemical cell is described. The cell usually includes a negative electrode that includes an alkali metal; a positive electrode that includes at least one transition metal halide; a molten salt electrolyte based on an alkali metal haloaluminate; and a sodium ion-conducting solid electrolyte partitioning the positive electrode from the negative electrode. The method is based on a treatment regimen that includes the step of applying a series of electrical cycles to the cell, wherein the series includes at least one deep discharge of the cell. Each discharge of the cell is usually followed by recharging the cell to its available capacity. | 06-05-2014 |
