Abstract: An uninterruptible power supply (UPS) includes a first battery set and a second battery set. The UPS includes a charging circuit to charge the battery sets using alternating current (AC) power. The UPS includes a slot receptive to insertion of different types of output modules that each include an inverter to convert direct current (DC) power from the first and second battery sets, including a first type that connects the first and second battery sets in parallel and a second type that connects the battery first and second sets in series.

Abstract: According to an example, a battery is charged using a charge voltage based on a present state of charge of the battery and a present ambient temperature of the battery. Additionally, the charge voltage may be based on the present state of charge of the battery, the present ambient temperature of the battery, and an age of the battery. The charge voltage may be retrieved from a lookup table that includes a plurality of reference charge voltage values at which to charge the battery for different ambient temperatures, different states of charge, or different ages of the battery.

Abstract: In an example, an apparatus includes a charger for rectifying a direct current charge from an input alternating current voltage. A battery pack stores the direct current charge in a first string of battery modules and a second string of battery modules. An inverter is connected directly to the battery pack and inverts the direct current voltage to an output alternating current voltage. In one example, the first string of battery modules is directly connected to the inverter in parallel with the second string of battery modules.

Abstract: Example implementations relate to concurrent alternating-current and direct-current. In one example, a device comprises a power module connected to a first power outlet, the power module connected to a second power outlet, and a controller to the power module to concurrently provide alternating-current (AC) power to the first power outlet and direct-current (DC) power to the second power outlet by switching a transistor including switching circuitry in response to an absence of AC input power to the device.
