A detachable DC power source includes: a reference surface extending in front-rear and left-right directions; support walls protruding upward from opposite ends of the reference surface and extending in the front-rear direction; battery-side rails protruding outward in the left-right direction from the upper ends of the pair of support walls and extending in the front-rear direction; and a first battery-side distinguishing region disposed between the support walls in the left-right direction and at a connection location between the reference surface and one of the support walls. A first battery-side distinguishing member is provided in the first battery-side distinguishing region and is directly connected to the one the support walls and to the reference surface. The detachable DC power source may be used to power an electrical device having a first device distinguishing part capable of receiving the first battery distinguishing member.

Power allocation in printing devices is disclosed. Independent load requests are received from printing device heater systems. A first load request is received from a first heater system and a second load request is received from a second heater system. Power grants are allocated based on a general power arbitration of a power source in response to the independent load requests. The power grants include a first power grant based on the first load request and a second power grant based on the second load request. The power grants are adjusted based on a contextual printing condition. The power grants are adjusted to apportion a measure of the second power grant to the first power grant rather than provide the measure of the second power grant to the second heater system if a print substance density is outside a selected print substance density threshold.

A power supplying device comprising a battery, a charging circuit and a DC-AC conversion circuit is provided. The charging circuit is electrically coupled to an AC power source and configured to charge the battery. The DC-AC conversion circuit is electrically coupled to the battery and configured to supply an AC output. When the power supplying device is powered on, both of the charging circuit and the DC-AC conversion circuit are enabled.

A method for the reduction in the electricity consumption of an electrical load (2) placed along an electric line (3), said method comprising the steps of: —determining a phase shift existing between the current and voltage along the electric line (3); —implementing the following procedure if said phase shift falls within a predetermined range: i) performing an interruption of current to the electrical load (2) of a duration less than a predetermined value; ii) modifying an electrical characteristic of an additional electrical load (6) as a function of the phase shift; iii) putting or maintaining said additional electrical load (6) in parallel with the electrical load (2).

A battery pack is configured to supply electric power to an electric work machine, such as a power tool or outdoor power equipment. The battery pack includes a first battery-signal terminal and a second battery-signal terminal. The first battery-signal terminal outputs, to the electric work machine, a first signal indicating that discharging is to be prohibited or permitted. The second battery-signal terminal outputs, to the electric work machine, a second signal indicating that discharging is to be prohibited or permitted. Thus, two communication paths are provided for transmitting signals to permit or prohibit discharging of the battery pack.
