Removable Battery PackReferring to
The battery assembly 100 can be removed by an operator from a piece of equipment without the use of tools and recharged using a charging station, as described further herein. In this way, the operator may use a second rechargeable battery having a sufficient charge to power equipment while allowing the first battery to recharge. In addition, the battery assembly 100 can be used on various types of equipment including indoor, outdoor, and portable jobsite equipment. Due to its uniformity across equipment, the battery assembly 100 can also be used as part of a rental system, where rental companies who traditionally rent out pieces of equipment can also rent the battery assembly 100 to be used on such equipment. An operator can rent a battery assembly 100 to use on various types of equipment the operator may own and/or rent and then return the battery assembly 100 to be used by other operators on an as-needed basis.

The handle 110 includes an outer surface 111 and an inner surface 113 positioned nearer the battery pack 105 than the outer surface 111. The inner surface 113 includes a movable member 135 configured to be operable by the operator to unlock the battery assembly 100 from a charging station and/or a piece of equipment. When depressed, the movable member 135 moves inward toward the inner surface 113 and moves the lock 143 out of engagement with a respective feature on a charging station and/or piece of equipment. In this way, when an operator grasps the handle 110, the operator can, at the same time and with the same hand, easily depress the movable member 135 to disengage the battery assembly 100 from a piece of equipment or charging station.

In some embodiments, the rack charging system 200 and/or the bench top charging system 400 use sequential charging while charging multiple battery assemblies 100. Sequential charging includes charging different battery assemblies 100 at different times so that not all battery assemblies 100 are charged at once potentially resulting in an overload on the utility service system. The sequential charging may determine which battery assemblies 100 need to be charged more than others by monitoring the charge levels of all connected battery assemblies 100 and supply charge to those assemblies 100 while switching off power supply to battery assemblies 100 that may already be fully charged.
Referring to
In addition to the charging systems described above, the battery assembly 100 can also be charged while inserted on the equipment or tool on which the battery assembly 100 is used. A user can leave the battery assembly 100 inserted and plug the equipment or tool into an outlet to charge the battery assembly 100. In this embodiment, the charging system is included with the tool or equipment such that no external charger is necessary.

The rear battery receivers 635 may be configured to receive the battery assemblies 100. The mating feature 140 on the battery assemblies 100 may be configured to couple to an exterior of the rear battery receivers 635. The battery assemblies 100 located on the rear battery receivers 635 may be used as backup power sources for the inverter 600. If the battery assembly 100 located inside the main battery receiver 630 is depleted of energy, one of the battery assemblies 100 located on the rear battery receivers 635 may be hot-swapped into the main battery receiver 630.
The main battery receiver 630 is a “closed” battery receiver 631 having a perimeter 632 that is closed and fully surrounds a battery assembly 100 coupled to the main battery receiver 630. The rear battery receivers 635 are “open” battery receivers 636 having a perimeter 637 that defines a gap 638 (e.g., opening) and partially surrounds a battery assembly 100 coupled to the rear battery receiver 635. The open battery receiver 636 has a smaller footprint than the closed battery receiver 631 when a battery assembly 100 is not coupled to the battery receiver.

A user may activate front handle release 606 and extend the front handle 605. The user may then tilt the inverter 600 forward into a rolling position that allows the inverter 600 to be rolled around via the wheels 615. The pivot assist bar 620 may or may not be used in this process. To use the pivot assist bar 620, the user may step down onto the pivot assist bar 620 to assist in tilting the inverter 600 into the rolling position.

The DC output 670 may be configured to draw DC power directly from the battery assembly 100, without the need to be converted to AC power using the inverter 600. The DC power from the DC output 670 may be used to power electronic equipment (e.g., a lighter receptacle, a portable GPS device, a mobile phone, etc.).
The one or more AC outputs 675 may be configured to be a 120 Volt AC power source. The inverter 600 may convert the DC power from the battery assembly 100 into an AC power. The AC power converted by the inverter 600 may be accessed at the one or more AC outputs 675. The AC power from the one or more AC outputs 675 may be used to power indoor and outdoor power equipment (e.g., light towers, space heaters, speakers, power tools, etc.).
The one or more USB outputs 680 may be configured to act as a 5 Volt DC power source. The one or more USB outputs 680 may be configured to draw DC power directly from the battery assembly 100, without the need to be converted to AC power using the inverter 600. The DC power from the one or more USB outputs 680 may be used to power small electronic equipment (e.g., a mobile phone, a small fan, a small battery pack, etc.).

The light tower 800 is configured to accept the inverter 600 with or without battery assemblies 100 coupled to the main battery receiver 630 and the rear battery receivers 635. The inverter 600 may act as a power source for the light tower 800. The AC input 810 is configured to receive the 120 Volt AC power from the rear AC output 640. With the main battery receiver 630 and the rear battery receivers 635 all containing a battery assembly 100 and hot-swapping out depleted battery assemblies 100, the inverter may be able to power the light tower 800 for up to 6.5 hours at maximum brightness.

The stabilizer platform 805 may be configured to pivot between a raised position or a lowered position relative to the base 801. In the lowered position, the stabilizer platform 805 is configured to support the light tower 800 from tipping (e.g., from wind, jarring, etc.). The stabilizer platform 805 includes a knob 875. The knob 875 is configured to secure the stabilizer platform 805 in the lowered position (e.g., to prevent from raising). The knob 835 may be either tightened or loosened to either secure or release the stabilizer platform 805, respectively. For example, the knob 835 must be in a loosened position to either raise or lower the stabilizer platform 805. The AC input 810 is configured to be covered (e.g., hidden, obstructed) by the stabilizer platform 805 when the stabilizer platform 805 is in the raised position. This can prevent a user from powering the light tower 800 unless at least the stabilizer platform 805 is lowered. In some embodiments, the knobs 870 and 875 are the same type of knob.

The mast control 828 may be configured to control the actuator 890 to raise and lower the intermediate mast segment 840. The mast control 828 may be configured to be toggled or held in an up or a down position. The up position may raise the actuator 890 and the down position may lower the actuator 890. In some embodiments, the intermediate mast segment 840 may be raised and lowered by manual methods (e.g., hand crank). The pulley 850 is fixedly coupled to the intermediate mast segment 845 with a cable fixedly coupled to each the base mast segment 835 and the terminal mast segment 845. As the actuator 890 raises the intermediate mast segment, a force is induced on the cable. The force on the cable causes the terminal mast segment to raise or lower along with the intermediate mast segment. In some embodiments, this is referred to as a telescopic mast.

If “coupled” or variations thereof are modified by an additional term (e.g., directly coupled), the generic definition of “coupled” provided above is modified by the plain language meaning of the additional term (e.g., “directly coupled” means the joining of two members without any separate intervening member), resulting in a narrower definition than the generic definition of “coupled” provided above. Such coupling may be mechanical, electrical, or fluidic.
The term “or,” as used herein, is used in its inclusive sense (and not in its exclusive sense) so that when used to connect a list of elements, the term “or” means one, some, or all of the elements in the list.
