  • Patent number: 8957685
    Abstract: An electrical charge detection device for measuring the electrical charge of a dry cell battery comprises electrically conductive arms joined with a rivet pin at their proximal ends with curved tips at their distal ends. The junction formed by the proximal ends has a light source mounted on the planar top surface and is in electrical contact with the pin. The curved tips at the distal ends of the arms are angled to form inward curved prongs that connect with the polar ends of a power source such as a battery. When the arms are squeezed together, one tip contacts the cathode of the battery and the other touches the anode so that any charge in the battery will travel up the arms thereby lighting the bulb. The degree of brightness illuminated by the bulb is indicative of the electrical strength or power remaining therein.

The multi-function remote control comprises a micro controller unit (MCU), a residual power display, a button unit, a current detector and a voltage detector. The MCU couples to the rechargeable battery and then charges or discharges the rechargeable battery. The current detector measures the current of the rechargeable battery and correspondingly outputs a current-value signal (Si) to the MCU. The voltage detector measures the voltage of the rechargeable battery and correspondingly outputs a voltage-value signal (Sv) to the MCU. Then, the MCU obtains the residual power of the rechargeable battery by means of analyzing the current-value signal (Si) and voltage-value signal (Sv), and then reveals the corresponding residual power by the residual power display. Whereby, the multi-function remote control might have functions of remote control, charging and revealing residual power.

    Abstract: Disclosed herein is a voltage sensing member constructed in a structure in which linear mounting parts are mounted to supporting parts coupled to the bottom of a battery module, conductive sensing parts are mounted on the mounting parts while the conductive sensing parts are in elastic contact with electrode terminals of battery cells, and the sensing parts are electrically connected to a battery management system (BMS). The voltage sensing member according to the present invention is manufactured by a simple assembly process without using a plurality of members for mechanical coupling and electrical connection. Consequently, the present invention has the effect of reducing the manufacturing costs of the voltage sensing member. Also, the voltage sensing member is maintained in elastic and stable contact when external impact or frequent vibration is applied to the voltage sensing member. Consequently, the present invention has the effect of performing stable voltage sensing operation.

  • Patent number: 7532492
    Abstract: An accessory device voltage management system includes an accessory device selectively coupled to a host. The host provides a bulk power supply and a low power supply voltage to the accessory device. The host receives accessory device parameters from the device and determines if the accessory device is a valid and supported device and, if so, sends commands to the accessory device to couple the bulk power supply voltage to a power supply circuit in the accessory device. The power supply circuit in the accessory device generates at least a first regulated voltage output.

  • Patent number: 6881974
    Abstract: Various aspects of the invention provide methods of manufacturing probe cards and test systems which may test microelectronic components using such probe cards. In one specific example, a probe card may be manufactured by forming a plurality of blind holes in a substrate, with each hole having a closed bottom spaced from a back of the substrate by a back thickness. An electrically conductive metal may be deposited on the substrate to fill the holes and define an overburden on the substrate. The metal in each hole may define a conductor. At least a portion of the overburden may be removed to electrically isolate each of the conductors from one another. A portion of the substrate including the back thickness is removed to define an array of pins extending outwardly from a remaining thickness of the substrate, with each pin being an exposed length of one of the conductors.

  • Patent number: 6191591
    Abstract: A cell grading test fixture includes an array of cell sockets electrically interconnected in series so that current through the entire array of cells flows through each of the cells once inserted into the fixture. Associated with each socket is an indicator which indicates to the operator when a cell voltage has fallen to a predetermined level. Each socket of the test fixture includes a spring-loaded switch contact such that upon removal of a cell which has dropped below a threshold voltage, the movable contact engages the contact of an adjacent socket, shorting out the cell location such that the series circuit of cells continues to provide a current path for the remaining cells.

  • Patent number: 6103408
    Abstract: In an electric battery, an electronic clock is integrated in the battery container in order to monitor battery functions. The frequency of the electronic clock is varied as a function of at least one characteristic value of the battery. In one embodiment, the frequency of the electronic clock increases with increasing electrolyte temperature and increasing deviation of the terminal voltage from the open-circuit voltage of the battery. Specifically, the electronic clock may be connected to a measurement probe immersed in the electrolyte through which voltage is supplied to the electronic clock and the battery temperature and the electrolyte level are measured. The electronic clock signals its stopping as soon as a pre-assigned nominal running time is reached.

  • Patent number: 6008652
    Abstract: A battery tub tester is disclosed that tests the individual batteries, battery accessories and connections as they are being assembled into a battery tub for an electric vehicle. The batteries and battery tub accessories, including temperature sensing devices and battery monitor modules, are mounted and electrically connected in the battery tub in accordance with a known battery tub assembly scheme. As the assembler mounts and connects the batteries and battery tub accessories, the tub tester determines the battery voltages of each battery after it is mounted and connected within the tub to determine if the batteries have the desirable voltage and will operate as they are intended and are connected properly. Additionally, the tester determines the temperature readings as the temperature sensors are being mounted, to determine if the temperature sensors will operate as intended and are connected properly.
