BEQ1 - LiFePO4 Battery Equalizers
Beta testing the newly developed equalizers on 4ea LiFePO4 cells provided by www.LionEV.com sent to Hot Juice Electric by me from: www.TexomaEV.com
Date: Tue, April 25, 2008
The parts to modify the BEQ1's for LiFePO4 prototypes arrived yesterday evening and I completed a set for the test pack. I even managed a preliminary test that yielded very positive results! This weekend will be very busy with testing and hopefully, completion of a beta design solution to solve this issue, of balancing a LiFePO4 traction pack.

Mike and all,
It was, indeed a very busy weekend! There was more work involved than
I expected, including having to add a few parts to slow the regulators
response. It turns out the change of current near the "full" part of a
charge cycle is so sharp it would set up an oscillation with adjacent
cell/regulator pairs. Most of the weekend was spent fine tuning the
response until it was perfectly stable. I managed to perform 5 discharge
/ charge cycles and all worked great.
Cell #3 in this test pack is definitely bad, which makes discharge
testing a bit cumbersome, but it is great for testing the regulators. For
example, it is interesting, how the regulator on the bad #3 cell turns
on immediately as soon as charging starts. Then, as the other cells
approach the "full" knee of their charge curve, the #3 cell regulator
shuts off since #3 is still not "full". Finally, all of the regulators
are "on" indicating all cells are charged. This means that even though
cell #3 is bad, its regulator protects it against further damage while
the other cells are charging at a much higher rate.
I still have at least one charge test before concluding the design is
ready. I expect to do that this (Monday) evening. The test is a high
(>20 Amp) charge rate.
More to come…
Date: Tue, April 29, 2008
Last evenings test was a high current charge to see how the regulators handled the current, specifically with the bad #3 cell. The test went great although the pack would not draw more than 8 amps at 14.8 volts. Another test was to parallel two regulators across the bad cell to see if they would share the current evenly when the charge current was pushed up to 10 amps (about 15.8 volts). With 15.8 volts at the power supply, all regulators were on and no cell was over 3.7 volts, including the bad one. (The remaining 1 volt was voltage drop across the leads).
I am very pleased with the results. I think we are ready to make plans for putting them into operational tests. I plan to design a footprint to house 4 regulators in one slim package with the same or similar dimensions as a "pop tart" cell. It would have the terminals on the top edge to match the orientation of the cell terminals. I would also like to add signaling terminals that could be connected to a relay, light, etc. to indicate full charge, and fault conditions. At this point, however, I think it might be best to proceed with the original BEQ1 format as operational test subjects. That would get regulation in place faster and would insure the design is operationally sound before proceeding to a finalized product.
NOTE: The 4cells I built up for HotJuiceElectric, were of some I had left over from another build. I looked back, and noticed that one of the cells was part of a pack, I had originally used for demonstration purposes, yet it wasn't abused that I know of, but I suspect it is the cell that is bad in this original test pack.....

Filed under irresponsible photography: I was driving down the Eisenhower Expressway as I have a thousand times before when I was struck by the windows on the old Post Office building, which was built before the expressway, but with a gap for the expressway to eventually run below it, which it still does today. My camera was sitting on the passenger seat so I grabbed it and took some shots, blind of course, out the front of my car. Probably inadvisable.
Upsampled it, smoothed it. Equalized it, Retouched it here and there.
Tough picture to work on because it's almost perfect ....

After shootouts Meveščak wins a point against Austrian Linz...
Medveščak had a lead 3:1 after the first period, with goals from Morley (11', 13') and Netik (19'), while Brod (16') scored for guests. Linz equalized through Lebler (25') and Locke (28'). Zagreb players scored for the lead again through Olden (38'), but only a minute before the end of the second period Lukas equalized again. The third period and overtime went with no goals, and in shootout the Linz goalkeeper Ouzas excelled and defended all three shots from Medveščak players, and Leber was the only one to score for the win.
»It's a shame, I am sorry that we missed the win. Everything was on our side, but we obviously still have a problem with powerplay. It started well, but Linz came back quickly and didn't surrender to the end«, commented Sašo Rajsar, and added: »We don't have much time until the next game. We must do the work to get even better and revenge to Villach for the away loss from the season start, in front of our supporters.«
The Bears hold the 9th position with 12 points, and their next game is already on Tuesday, in Zagreb, vs. Villach (7.15 p.m.)

Il Programmable EQ di Source Audio è una versione moderna, completamente aggiornata ed estremamente semplificata dei tradizionali equalizzatori a pedale. Questo pedale compatto, costruito in robusto alluminio pressofuso, consente di accedere velocemente e senza-mani a quattro differenti setting di equalizzazione precedentemente programmati. Qualsiasi sia il tuo strumento, stile e genere musicale, il Programmable EQ di Source Audio è lo strumento essenziale per scolpire il tuo sound dal vivo.
Il Programmable EQ permette di agire su un range di +/- 18dB su sette bande di frequenza, più una banda di frequenza aggiuntiva sui 62Hz, accessibile attraverso la funzione 'Estendi Ottava' che ottimizza sistematicamente lo spettro di frequenze del pedale adattandolo al range di frequenze specifico del basso. Una volta costruito il tono di chitarra o basso desiderato, è possibile salvarlo in uno dei quattro preset programmabili. Ogni preset è facilmente richiamabile attraverso la funzione scrolling del footswitch. Tenendo premuto il pulsante, il pedale visualizzerà progressivamente, con una velocità regolabile, i quattro preset salvati finché, togliendo la pressione, ci si fermerà all'equalizzazione prescelta.
L'input MIDI inoltre permette l'accesso remoto ai preset dell'utente nonché di attivare o disattivare l'effetto (engage/bypass). Connettendo poi il Programmable EQ a un segnale MIDI proveniente da un POD, da un Eventide Space Reverb, da una pedaliera TC Electronic Nova System o da qualsiasi altra unità multi-effetto MIDI-compatibile, potrai espandere enormemente gli orizzonti del tuo tono all'interno di ogni preset.
Il Programmable EQ offre un significativo Clean Boost che arriva fino a 12dB. È possibile utilizzare il boost pulito per un aumento del volume interamente trasparente o dare ad un amplificatore la spinta necessaria per un naturale e aggressivo break-up. Il Hardwire True Bypass (che collega in e out attraverso un piccolo relay) garantisce una migliore affidabilità, la possibilità di switching remoto e un bypass capace di mantenere il segnale "hardwire" non effettato completamente inalterato.
Inoltre, la funzione di scorrimento Auto-scrolling, che scorre automaticamente tra tutti i quattro preset a velocità variabile, crea effetti spettacolari simili a quelli di unità sequencer o tremolo. Il pedale funziona con una batteria da 9V (inclusa) o con un alimentatore esterno opzionale.
Caratteristiche:
• +/- 18dB su sette bande di frequenza.
• Quattro preset indipendenti programmabili dall'utente e facilmente richiamabile tramite il footswitch.
• Funzione Octave Extend: ottimizza l'EQ per i bassi con una banda addizionale a 62Hz.
• Compatto e robusto box in alluminio pressofuso.
• 12dB di Boost.
• Funzione di scorrimento automatico: scorre automaticamente attraverso tutti i quattro preset per creare effetti unici simili alle unità sequencer o tremolo.
• Hardwire True Bypass: per una maggiore affidabilità e capacità di controllo remoto.
• Ingresso MIDI: richiamo preset, engage/bypass remoto via MIDI.
• DSP all'avanguardia : Processore di segnale digitale a 56-bit, SA601 e convertitori 24-bit.
• Alimentazione: batteria 9V (inclusa) o alimentatore (non incluso).
• Dimensioni: 11,4cm (profondità) x 6,4cm (larghezza) x 5,1cm Altezza.

Durante questa lunga esposizione alle luci del crepuscolo ho lentamente spostato il fuoco da infinito a 2 metri. In questa maniera ho messo a fuoco tutto il paesaggio visibile, dai ciuffi di un canneto in primo piano fino alle lontane luci di una strada, passando per alcuni alberi. Tutto a fuoco e niente perfettamente in dettaglio. “Equalizzazione” è la compensazione di un fenomeno, genericamente, e richiama il concetto di uguaglianza. In questa composizione tutti gli elementi sono sullo stesso piano e hanno la stessa importanza, dal grande al piccolo, dal naturale all’artificiale. Ci troviamo ancora una volta nell’Oasi di Punte Alberete.
