2. IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/IUoU_battery_charging

   IUoU is a DIN -designation [ 1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging. It consists of three phases (or stages), to be executed by a battery charger. The three phases are: I-phase (constant electric current ), Uo-phase (constant over- voltage ), and U ...

3. Talk:IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/Talk:IUoU_battery_charging

   Stage one and two confused. The statement at the end of stage one that some chargers will keep the voltage at uMax and reduce the current to 80% of the constant current value before proceeding to Stage 2 is complete nonsense. That is the definition of stage 2, keeping the voltage constant and reducing the current, so literally the charger has ...

5. Lithium–sulfur battery - Wikipedia

   en.wikipedia.org/wiki/Lithium–sulfur_battery

   The lithium–sulfur battery (Li–S battery) is a type of rechargeable battery. It is notable for its high specific energy. [ 2] The low atomic weight of lithium and moderate atomic weight of sulfur means that Li–S batteries are relatively light (about the density of water). They were used on the longest and highest-altitude unmanned solar ...

   At 500 grams and with a retail price of $199, it's not meant to compete with regular lithium ion battery packs -- in fact, the Upp behaves very differently. For a start, you don't need to charge it.

8. Type 2 connector - Wikipedia

   en.wikipedia.org/wiki/Type_2_connector

   The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
