Post-TDE2017 TLC for TW560 (Part 2/3)

With part 1/3 TW560 taken care of, it’s time to put my focus on two other issues: After just one day of constant wiper usage during a storm in Hungary, TW560’s acrylic windscreen is badly scratched and needs urgent attention. When the sun or lights from oncoming traffic hits the windscreen, I’m almost blind. Lots […]

Post-TDE2017 TLC for TW560 (Part 1/3)

Unlike our many other yearly TWIKE adventures, TDE2017 took a heavy toll on TW560. Time to give TW560 some TLC and make TWIKEing great again! 🙂 First stop is at Andreas Martin’s Ksenotek, Switzerland’s newest TWIKE service partner in northern Switzerland. The 360° sphere below was created by me during TWIKE Klub Switzerland’s 2016 general […]

Hello 2017

Welcome 2017 – I haven’t been blogging for a while, there hasn’t been much to blog about anyway – having been rather busy with (international) travel and finally some well-deserved vacation, this entry is somewhat of a quick re-cap of the last few months. After my TWIKE-related accident it took surprisingly long to get rid […]

Update: Compact 3.7kW charger project

Picking up after where we left a week ago: After some debugging, I’ve been able to start communicating with the charger.   Assuming the hardware-related problems I had to solve before successfully receiving my first CAN packet are rare, I must say that the steps required to actually get packets from the bus and on […]

Solar TukTuk & TW560

For some time now, I’ve been following a very interesting project: Tejas, the Solar Tuk Tuk. Naveen Rabelli is driving his DYI-conversion of an Ape three-wheeler on a 10’000km trip from India to England. On his trip he is proving that very simple sustainable technology can be as reliable as mass-produced conventional technology and at […]

New Project: Compact 3.7kW charger & configuration

After installing TW560’s latest battery pack and testing it thoroughly, one of the points I definitely want to address is reducing full-charge time. With a potential maximum of 18.9kWh having to go into the batteries, my current setup with 6.8kWh peak charging capacity means I’m charging for at least 3 1/2 hours. Adding chargers is […]

My first 35E-week – a recap

New Battery Pack: How far can I go on a charge?

Every time when changing something related to batteries, many other parameters potentially change at the same time: Chemistry, response to load, max/min voltages and discharge curves, etc. In a way, it feels like being a novice TWIKE pilot again – you really don’t know how your battery will react and – in consequence – how […]

Finally: My 51Ah pack has arrived!

Samsung’s 35E cells weren’t available when I ordered TW560’s new Dreifels 51Ah battery pack. Thanks to a very kind offer by Ralph from dreifels, I was still able to go on my yearly TWIKE adventure and experience a large pack / range with his personal 29E/45Ah pack. During my vacation Dreifels sent me an email […]

A 2nd Life for TW560’s previous batteries

My last battery-related entry was on TW560 getting a new battery pack. (Finally, I have the time to write an entry after my epic 10-day TWIKE adventure across some of the highest passes of Europe with less charging stops. 🙂 ) This entry is dedicated to the previous’ pack’s second life as a stationary battery […]
