There are several 3rd party applications that let you take the Analogger data and use it to generate a dashboard of gauges and readouts in a video overlay. This way you can greatly enhance the appearance of video clips of your ebike adventures. You can choose which data you want the viewer to see and how it is presented, without trying to point the camera downwards to capture the actual CA screen.
The combined CA and GPS data files can be used with our online trip analyzer software to produce and share graphs of your ebike trips, allowing you to visualize how your energy usage varied along the terrain. You can see how different grade hills affect your power usage or regenerative braking current. You can see how many amp-hours are used on different legs of the trip, and with a V3 CA and a torque sensor you can see all your human power and cadence details too.
Another useful application of the analogger involves recording and logging discharge curves of battery packs. A simple XY plot of the battery voltage versus amp-hours is an invaluable tool to quantify and characterize the state of a battery, be it for warranty purposes, initial pack evaluation, life cycle degradation studies etc. Typically for this purpose the battery can be discharged into a resistive load.
Vehicle Performance Modeling
For anyone doing more analytic work in electric vehicle R&D, the 5Hz data mode allows you to capture entire vehicle dynamics and make truly objective comparisons between systems and options. You can see just how many watt-hours are used to get from 0 to XX kph with different levels of acceleration. With an accurate motor model, you can deduce the mechanical output power and extrapolate vehicle parameter models such as CdA and rolling resistance.
Documentation and Firmware
The Analogger firmware has not changed since 2011, but if you have an earlier device from 2010-2011 that you want to update to the current V12.0 firmware then please download the following update kit and follow the instructions.
Cycle Analogger Firmware Updating Package for Windows
Cycle Analogger Firmware Updating Package for Linux
The Analogger can also be hardware modified by the user (not done at Grin) to transmit the GPS data to be displayed by some select CA3 firmwares. The instruction set is here and the firmware can be obtained by emailing us.
