A battery management system for batteries, such as, but not limited to, electric vehicle battery packs and cells, lithium iron phosphate batteries, lead acid batteries, gel batteries, and absorbed gel mat batteries, in engine start applications is disclosed. The battery management system may include a minimum discharge current control module configured to operate at least partially in current limit mode to limit output power current flow from one or more battery cells to prevent discharge of all charge from the battery cell yet enable a low amperage powered device to remain powered by the battery cell.

A battery management system for batteries, such as, but not limited to, electric vehicle battery packs and cells, lithium iron phosphate batteries, lead acid batteries, gel batteries, and absorbed gel mat batteries, in engine start applications is disclosed. The battery management system is configured to control the charge and charging of each cell individually. The battery management system may be configured to control the charge of a battery which may consist of a plurality of cells, such as, but not limited to, lithium iron phosphate cells, and in at least one embodiment, the battery may consist of, but is not limited to being formed from, four lithium iron phosphate cells connected in series and a battery management system to ensure proper charge and safe operation.

A battery such as, but not limited to, electric vehicle battery packs and cells, lithium iron phosphate batteries, lead acid batteries, gel batteries, and absorbed gel mat batteries, may include a battery management system for engine start applications. The battery may include a first power port configured to receive power from a first power source and a second power port configured to received power from a second power source, whereby the first and second power sources are different.

Briefly, example methods, apparatuses, and/or articles of manufacture may include a vehicle assistance controller to convey content to one or more display devices. The vehicle assistance controller may operate to access a user input device to determine an assistance topic for charging and/or discharging one or more energy storage elements (e.g., one or more batteries) of the vehicle. The vehicle assistance controller may additionally operate to determine a delivery mode for the content, which is applicable to the assistance topic, based on the access of the user input device, and to deliver the content to the one or more display devices via the determined delivery mode.

A method for operating a motor vehicle including a traction electric motor, wherein the traction electric motor can be actuated for producing a creep torque that brings about a slow movement of the motor vehicle, wherein a plurality of creep torques of different magnitude can be set by a user of the motor vehicle.

A refuse vehicle can include a battery, a display device, a door, and a control system. The batter can power the refuse vehicle. The display device can display one or more user interfaces. The control system can include one or more memory devices. The one or more memory devices can store instructions that can cause, when executed by one or more processors, the one or more processors to determine a state of charge of the battery, detect that the door has moved from a first position to a second position, and transmit a control signal to the display device causing the display device to display a user interface including the state of charge of the battery.

A state determination unit determines whether a state of traveling performance of a fuel cell vehicle is a normal performance state, a limited performance state, or a low performance state. When the state determination unit determines that the fuel cell vehicle is in the normal performance state or the limited performance state, a traveling propriety determination unit determines that the fuel cell vehicle can travel. A notification control unit performs a limited state notification when the state determination unit determines that the fuel cell vehicle is in the limited performance state and the traveling propriety determination unit determines that the fuel cell vehicle can travel.

In a hybrid vehicle, noise occurrence caused in a rectangular wave control of a motor is restricted when a motor running mode is selected with a converter boosting limit applied. A motor controller for a hybrid vehicle mounted with an internal combustion engine and a motor as power sources is provided. The motor controller includes a converter capable of boosting a voltage supplied from a power supply device; an inverter which converts an output voltage of the converter to an AC voltage and applies the AC voltage to the motor; and a control unit which controls the inverter to drive the motor by switching between two or more control modes. When a running mode to drive the vehicle by a motor power alone is selected with a boost limit applied to the output voltage of the converter and when the motor is driven in a rectangular wave control mode or an overmodulation PWM control mode, the control unit raises the output voltage of the converter higher than a boost limit value and controls the inverter such that the control mode is switched to drive the motor in a sinusoidal PWM control mode.

A battery management system for batteries, such as, but not limited to, electric vehicle battery packs and cells, lithium iron phosphate batteries, lead acid batteries, gel batteries, and absorbed gel mat batteries, in engine start applications is disclosed. The battery management system is configured to control the charge and charging of each cell individually. The battery management system may be configured to control the charge of a battery which may consist of a plurality of cells, such as, but not limited to, lithium iron phosphate cells, and in at least one embodiment, the battery may consist of, but is not limited to being formed from, four lithium iron phosphate cells connected in series and a battery management system to ensure proper charge and safe operation.

A charging system for Electric Vehicles (EVs), comprising an AC/DC charger; an AC/DC charging cable being connected to the battery of an EV, to be charged, via an adaptor in the EV, for charging the battery or other electric components of the EV with AC or DC power, or both; a data exchange interface, added to the charging cable, and being connected to predetermined computerized subsystems of the EV; a data connection to a remote computation cloud and/or to remote serves, which are equipped with dedicated software for connecting to the EV via the data exchange interface and performing remote operations and data exchange with computerized subsystems of the EV according to predetermined credentials and communication protocols.
