Abstract: A technique controls charge on a lithium battery of a utility vehicle. The technique involves operating electronic circuitry of the utility vehicle in a normal operating mode in which the electronic circuitry charges the lithium battery to a normal charge level. The technique further involves, after operating the electronic circuity in the normal operating mode, transitioning the electronic circuitry from the normal operating mode to a storage mode in which the electronic circuitry is configured to set an amount of charge on the lithium battery to within a predefined storage range (or level) which is lower than the normal charge level. The technique further involves, in response to transitioning the electronic circuitry, adjusting the amount of charge on the lithium battery from an initial charge level which is outside the predefined storage range to an adjusted charge level which is within the predefined storage range.

Abstract: A battery management system (BMS) controls lithium battery access on a utility vehicle. The BMS includes a battery interface that couples with a lithium battery, a load interface that couples with a set of loads of the utility vehicle, and control circuitry coupled with the battery interface and the load interface. The control circuitry mechanically disconnects the battery interface from the load interface in response to a sleep event. Additionally, after the battery interface is mechanically disconnected from the load interface, the control circuitry mechanically reconnects the battery interface to the load interface in response to a wakeup event. Furthermore, after the battery interface is mechanically reconnected to the load interface, the control circuitry maintains connection between the battery interface and the load interface to convey power from the lithium battery to the set of loads of the utility vehicle through the battery interface and the load interface.

Abstract: A charging system charges a lithium battery of a utility vehicle. The charging system includes a receptacle configured to couple with an external charger, a lithium battery configured to provide lithium battery power to a set of electrical loads of the utility vehicle, and control circuitry coupled with the receptacle and the lithium battery. The control circuitry is configured to detect connection between the external charger and the receptacle and, in response to detecting connection between the external charger and the receptacle, ascertain a charging state of the lithium battery. The control circuitry is further configured to output, based on the charging state, a control signal to the external charger through the receptacle, the control signal being configured to control charging output from the external charger to charge the lithium battery.

Abstract: A control system for handling a fault condition on a utility vehicle includes a lithium battery, a contactor configured to control electrical access to the lithium battery, and control circuitry coupled with the lithium battery and the contactor. The control circuitry is configured to detect, while the contactor is closed to provide a set of loads of the utility vehicle with electrical access to the lithium battery, onset of a fault condition. The control circuitry is further configured to perform, in response to detection of the onset of the fault condition, a set of remedial operations to address the fault condition. The control circuitry is further configured to perform, after a predefined amount of time has elapsed since the onset of the fault condition, a subsequent operation which opens the contactor if the fault condition remains and maintains closure of the contactor if the fault condition does not remain.

Abstract: Techniques control a utility vehicle. Such techniques involve storing electric power in a lithium battery of the utility vehicle. Such techniques further involve operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle. Such techniques further involve, after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque.

Abstract: A motion control system controls movement of a utility vehicle. The motion control system includes an electric brake that (i) provides mechanical resistance which inhibits a motor of the utility vehicle from turning when the electric brake is unpowered and (ii) removes the mechanical resistance to allow the motor of the utility vehicle to turn when power is provided to the electric brake. The motion control system further includes a lithium BMS having a contactor that closes to provide electrical access to a lithium battery and opens to remove electrical access to the lithium battery. The motion control system further includes control circuitry coupled with the electric brake and the lithium BMS. The control circuitry directs the lithium BMS to maintain closure of the contactor to provide power from the lithium battery to the electric brake in response to receipt of a tow signal.
