If I were an E-Bike designer (part II)

brains_11.jpgI wrote part one on the original blog site. Today, I received a reply from the President of Veloteq in Texas. So, here is the original post, and his reply.

Watching the snow outside and thinking about potential upgrades to my ebike, such as:

Xenon headlights. Same power use – much much brighter. LED rear brake light – less power, brighter. A programmable controller. I’d create different modes of travel, like “power saver” and “boost”. A beeper for the turn-signals, so I remember to turn them off after the turn. A power cell or failing that, a better battery than SLA. An on-board charging system. Disc brake (on the front at least). An accurate digital speedometer that doubles as a power use display. It should show power draw (when going up-hill), and power return, (when going down-hill).

Jim’s reply:

We are looking alternative lighting devices at this time. The Power Saver and Power Boost controls are not permitted in Canada or Ontario. It is usually a disguised method of increasing the power beyond the statutory limit of 500W Output. We are partnered with Powergenix of San Diego for the development of a nickel zinc battery PSU which will reduce the weight by nearly half, decrease the size a similar amount, have a conserable improved power strenght, more than double the number of recharge times available, and finally, decrease the recharge time to one hour for 80% and less than 2 hours for full capacity. We had an audible signal emitter for turns on earlier models,however, discontiined it because of customer complaints. You canot please everybody, but we will revisit this in a different fashion. On-board charging systems pose a particular safety problem which can cause them to fall afoul of electricity device regulatiohs in different jurisdictions. This is why we use the external charger. The external charger is also more covenient for periodically charging batteries that are removed for the bike for off-seaon storage and the chargin of spare PSU’s. The brakes we currently use are designed for motorcycle systems. We used disc brakes on earler models and found them much to difficutlt for owers to adjust and maintain. High quality drum brakes with relineable pads are the better alternative. We are cotinuing development of speedomters suited to our products. The amount of power actuallly regerated while brakig and coastiing is not sigificant. Even on electric autos, it does not exceed 5%. We consider only a methodf of replenishing some of the power consumed by accessories such as lights, etc.

    I can’t wait for the upgraded PSU! I hope it will fit into the existing product line, and, more importantly, I hope there’s an upgrade path for existing owners.

    How about a cigarette lighter port so that I can charge (or at least use) my cellphone. On Tuesday I avoided the main deluge under a railway underpass, but wouldn’t you know it, my phone died as I was trying to contact my wife to tell her where I was.

    That is a grate Idea and it should be easy to do yourself
    but how would it work lets say you have a 48 volts bat…?
    any one know how e could do that?
