摘要： Techniques involve managing lithium battery access on a utility vehicle. In accordance with such techniques, a wakeup circuit includes a set of inputs, a set of outputs, and control logic coupled with the set of inputs and the set of outputs. The control logic is constructed and arranged to, in response to detecting a wakeup event from circuitry of the utility vehicle via the set of inputs, close a switching apparatus of the utility vehicle via the set of outputs to connect a lithium battery of the utility vehicle to a set of loads of the utility vehicle. The control logic is further constructed and arranged to, in response to detecting a sleep event, open the switching apparatus via the set of outputs to disconnect the lithium battery of the utility vehicle from the set of loads of the utility vehicle.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Techniques involve controlling battery access on a utility vehicle. Such techniques involve monitoring status of input signals from a group comprising: a lithium battery system, a keyed switch, and a charging receptacle, comparing the status of the input signals to timeout settings stored in memory of the motion control system, initiating a timer based on comparison of the input signals to the timeout settings, and disconnecting at least one direct current (DC) path between a lithium battery interface and a power distribution interface of the utility vehicle in response to expiration of the timer. Such techniques further involve, after disconnecting, reconnecting the at least one DC current path between the lithium battery interface and the power distribution interface in response to a change in status of at least one of the input signals. Such techniques may be performed by a motion control system of the utility vehicle.
