The charging power supply for batteries may be variable under many circumstances, e.g., when using solar panels or air-driven generators as the energy source. The mismatch between the voltages of the power supply and the battery may cause significant charging inefficiency. In this paper, we use reconfigurable batteries to solve this voltage mismatch …
You can see that this battery is rated at 1.5 volts, but when we test it, we get 1.593 volts. The two values are close, but usually not the same. When the battery is dead or dying, we get a lower voltage.
We''ve had the chance to test drive a few Husqvarna battery string trimmers and, like its chainsaws, they don''t disappoint. The 330iKL was a beast during testing. We used it to thrash through ...
