Battery apparatus for use in starting railroad locomotives includes a portable housing. A Lithium Iron Phosphate chemistry Lithium ion battery is carried within the housing. The battery has a positive output lead and a negative output lead accessible from the exterior of the housing. A low voltage and high voltage protection module is positioned within the housing and connected to the positive output lead and the negative output lead. The module is constructed to switch the battery into a “sleeping mode” when the battery voltage reaches a low voltage or a high voltage condition. Output terminals are mounted on an exterior surface of the housing in a location available to be connected to a locomotive by interconnecting cables. When the voltage protection module switches the battery into the “sleeping mode” a push button on the housing is used to reactivate the apparatus.

Bi-directional, reverse blocking battery switch

Номер: US20120056261A1
Автор: Anthony C. Tsui, Anthony Chia, Hongbo Yang, HUI Teng, James Harnden, Liming Wong, Lynda Harnden, Ming Zhou
Принадлежит: GEM Services Inc USA

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.

An information processing apparatus capable of suppressing a secondary battery from being charged with an amount of charge current that can apply excessive load on the secondary battery, without a backup power source function of the secondary battery being impaired. When determining that a predetermined type of data is stored in a DRAM to be backed up by the secondary battery, the information processing apparatus selects a first constant current circuit and quickly charges the secondary battery with a large charge current output from the first constant current circuit. When determining that the predetermined type of data is not stored in the DRAM, the information processing apparatus selects a second constant current circuit and normally charges the secondary battery with a small charge current output from the second constant current circuit.

A dual battery charging and discharging system controls the configuration of multiple batteries arranged in multiple battery banks. The batteries within each bank are connected in series when powering an electrical load, such as a service motor, and are connected in parallel when charging. A microprocessor monitors the voltage levels of the batteries in each bank and controls relays to switch the electrical load over to a charged battery bank when the voltage level of the discharging battery bank drops below a minimum run threshold. The microprocessor also monitors the voltage levels of the charging battery bank and controls relays to cease charging when the voltage level rises above a minimum charge threshold. The batteries are charged by an alternator driven by a drive motor through a gear reduction system.

When a main switch ( 12 ) is turned ON, an electric operating machine ( 1 ) is put in the standby mode. With a trigger ( 13 ) being pulled in the standby mode, a power supply circuit ( 16 ) applies a voltage to a drive part ( 30 ). The power supply circuit ( 16 ) adjusts the voltage applied to the drive part ( 30 ) for a voltage corresponding to the pulling rate of the trigger ( 13 ). When the current running toward the drive part ( 30 ) exceeds the rated value of the drive part ( 30 ), the power supply circuit ( 16 ) automatically stops power supply to the drive part ( 30 ). On the other hand, when the output voltage of a battery ( 50 ) drops and the battery ( 50 ) is put in an overdischarge state, power supply to the drive part ( 30 ) is automatically stopped. When it is detected that the battery ( 50 ) undergoes an abnormal event, power supply to the drive part ( 30 ) is automatically stopped.

The circuit also may determine if the charge of any cell is at/below a second predetermined level, which may result in disconnecting of the battery from the load. The circuit may be radiation-hardened (e.g., via redundancy), through the use of two sets of field effect transistors, two logic gates, two groups of comparator circuits, and two relays. The circuit provides multiply redundant protection comprising: redundantly assessing the overvoltage determination; redundantly triggering battery isolation; and preventing inadvertent isolation and non-charging, occurring absent overvoltage, through redundant first and second relays.

The control device includes a safety capacitor that is interposed between the “gate/base” terminal and a power supply and charges when the discharge transistor is in the “conduction” mode, causing a progressive decrease of current at the “gate/base” terminal until the discharge transistor is biased to the non-conductive state.
