How we take a look at
Figuring out whether or not an influence financial institution lives as much as an organization’s promise entails greater than merely connecting it to a telephone and charging. Testing battery packs is finished over weeks, not days, and requires further tools as a way to make sure the batteries work as anticipated.
1. Upon receiving every battery pack, it’s totally charged, utilizing indicator lights as a way to trace cost stage.
2. Then to trace effectivity, we use an AVHzY USB Energy Meter in tandem with a DROK Micro Load Tester.
As we use the DROK load tester to empty the pack of energy, we’re capable of take a look at in opposition to a battery’s acknowledged most present, and confirm that correct shutdown mechanisms are in place ought to one thing go unsuitable throughout a charging session (corresponding to a tool drawing over the utmost amps).
Through the use of the AVHzY USB Energy Meter, we’re capable of monitor volts and amps, whole energy throughput, and whole period of time to deplete a battery from full to empty. The meter can create an Excel spreadsheet of your complete course of for future reference.
3. Subsequent, we recharged the battery, this time utilizing the AVHzY to trace it and chart the period of time it takes to succeed in full cost.
The AVHzY meter solves a shortcoming we had with our earlier technique with the PortaPow. Beforehand we had to make use of a GoPro digital camera to trace every battery by its cost cycle, because the PortaPow monitor would proceed to gather knowledge after the battery was totally charged (trickle charging is regular, and sadly interferes with our testing).
If a battery was able to charging by USB-C, we use that as an alternative of Micro-USB.
4. The AVHzY additionally has a characteristic inbuilt that checks a charging port for all of its supported charging requirements. We’re capable of run that take a look at and get an immediate readout to substantiate help for QC 3.0, for instance, without having to have appropriate telephones or units readily available.
Energy supply and cables
All of our exams had been performed utilizing the identical wall adapter and, when potential, USB-C or Micro-USB cable. This was completed to get rid of any discrepancies with wall adapters and cable throughput.
What to search for in a conveyable energy financial institution
