The present disclosure provides a portable standby starting device for a vehicle. The portable standby starting device includes a battery circuit, a load access detecting circuit, and a vehicle starting circuit, wherein the battery circuit is coupled to the load access detecting circuit and the vehicle starting circuit, and is configured to supply power to the load access detecting circuit and the vehicle starting circuit; the load access detecting circuit is coupled to the vehicle starting circuit, and is configured to detect whether the vehicle starting circuit is connected to a vehicle load; the vehicle starting circuit is configured to, when the load access detecting circuit detects the connection of the vehicle load, output a vehicle starting current for controlling an ignition operation performed for the vehicle.

A rechargeable battery jump starting device with a control switch backlight system. The control switch backlight system is configured to assist a user viewing the selectable positions of the control switch for selecting a particular 12V or 24V operating mode of the portable rechargeable battery jump starting device in day light, sunshine, low light, and darkness.

Disclosed herein are a vehicle or other system battery with a self-contained backup capability and a method for providing power to a vehicle using the vehicle or other system battery with a self-contained backup capability. In one aspect, the vehicle battery comprises, a main battery portion, a backup battery portion, and a control device for selectively communicating a transfer of energy from the backup battery portion to the main battery portion when a voltage level or other health indicator of the main battery portion is determined to be below a reference voltage threshold, wherein the main battery portion and backup battery portion are each re-chargeable via an alternator of the vehicle when the control device communicates the transfer of energy between the main battery portion and the backup battery portion.

There is provided an information processing apparatus including a travelable information display unit that displays before a discharge, regarding motor-driven movable bodies of a discharge source and a discharge destination driven by using electric power of batteries, information about places to which the motor-driven movable body of the discharge source can move using electric power of the battery left after the discharge by assuming, when information about a discharge amount discharged from the battery of the motor-driven movable body of the discharge source toward the motor-driven movable body of the discharge destination that receives power supply is input, a case in which the discharge amount is discharged from the battery.

A portable or handheld device or apparatus for jump starting a vehicle engine having a depleted or discharged starting battery. The portable or handheld device or apparatus for jump starting a vehicle engine includes a rechargeable lithium-ion (Li-ion) battery pack and a battery cell equalization circuit configured to prevent overcharging of one or more individual lithium-ion battery cells, which can cause fire, damage to the battery pack and device or apparatus for jump starting a vehicle, or personal injury to a user.

A jump starter device can include sensors to measure data of a vehicle coupled to the jump starter device. The jump starter device can include a controller configured to process the load data to determine the status of the load, such as the conditions of the vehicle connected to the jump starter.

A sealed lead acid (SLA) battery jump starter system that charges and recharges via a single two-way USB, thus providing for a two-way power in/power out feature using a single USB port. The output is preferably provided with a ‘triple voltage select’ feature. In one non-limiting embodiment, the triple voltage select feature can allow for an output of either 5V, 12V or 20V. The system provides for higher power, a versatile design, and higher efficiency by integrating a USB charging circuit to recharge a lead acid battery in conjunction with drawing power from the lead acid battery to provide a preferred triple output switch mode selectable power. The system provides for a USB rechargeable charging circuit that can be capable of providing input low power to recharge lead acid batteries and also providing power out (preferably triple voltage and current choices) to recharge high output electronics.

A portable charger capable of jump starting a 12 V car battery includes a charger battery, a jump start circuit operatively electrically connected with the charger battery and with an ignition power outlet, and a microcontroller for coordinating safety functions to establish or interrupt the operative electrical connection of the jump start circuit with the ignition power outlet. The ignition power outlet comprises a positive power socket, a negative power socket, a positive sensing socket and a negative sensing socket. The sensing sockets are electrically isolated from the power sockets, and the microcontroller senses voltage across the sensing sockets and is configured to interrupt the operative electrical connection of the jump start circuit to the ignition power outlet until proper voltage is sensed across the sensing sockets.

The invention relates to a method for addressing at least one bus subscriber, in particular a control device or sensor, which is connected to a bus system for the purpose of exchanging data, and which is supplied with DC voltage in order to supply the bus subscriber with supply voltage rectified as defined via a DC voltage input of said bus subscriber. It is proved according to the invention that the respective bus subscriber detects the polarity of the DC voltage at its DC voltage input, selects a predefined address depending on the detected polarity, and assigns the selected address to itself for the purpose of exchanging the data. The invention further relates to the bus subscriber and a system consisting of a bus system and exactly two bus subscribers of such kind. The invention also relates to a motor vehicle.
