Zero Motorcycles Forum | 2013+ / Re: Charging via motor controller ( the future ) ?

« on: July 18, 2015, 01:32:30 PM »

Hello together,

the so called inverter charging exists.
It is the electric car Renault ZOE.
The inverter is able to charge with up to 40 kW and uses the motor coils as load inductivity.

This is possible because the engine is a synchronous type with seperate excitation which produces no torque if not excited.
The inverter is normally working with a 400 Volt battery so that the voltage is no problem.

My wife bought that car a month ago and you hear the noise of the motor coils when charing.

Zero Motorcycles Forum | 2013+ / squeaking rear break, how i fixed it

« on: August 30, 2014, 12:39:34 PM »

The last weeks i more and more often heard a squeaking noise from the rearbrake of my 2014 SR, espacially when pushing it into garage. Additional there comes a special noise from the holes of the brake disc when braking only slightly at low speeds.
A kind of rattling.
I removed the brakepads (its only one screw to release) and saw the reason :
Pads contain small pieces of brass wires and at the edges of the pads tiny wire ends stand up like little springs and cause that noise. An edge has developed.
I took a rasp and smoothened the edges in a 45 degree angle, not much, about 1 mm so that a bezel can be seen.
The effective breaking surface is reduced nearly not by that.
i checked it, the squeaking and rattling has dissapeared.

Are there other brakepads availble without brass addon ?

Zero Motorcycles Forum | 2013+ / Re: My battery pack capacity is increasing

« on: June 22, 2014, 12:00:43 PM »

Hello together,
i observed the same effect. (Zero SR without power tank)
After 2 load cycles i succedded to ride 165 km from 100% to total empty .
Average spped was about 70 km/h

10 cycles later the batterypack shows a remarkable increase in capacity.
Last week i drove 141 km and had 34 % charge left. (average speed 55km/h)
The calculated rest range had been 74 km.

A friend, owner of a city el told me, that this training effect is normal for LiPo batteries.

Hello, here is Arno.

your proposal is of interest for me too, but i fear that i will loose my 5 years battery warranty in case of connecting own loaders.
A official statement from zero would be very helpful here.
The battery connector is a SBS75XBRN.

There are four auxiliary contacts with unknown function for me.

As i know you need a CC-CV characteristic.

Hello Richard230,

i think you have the range record till now !

I am owning a brandnew zero SR since 2 weeks and drove 161 km (100.0 Miles) till 0% battery level last week. Controller shut of the last 200 meters every second, same effect as reported from you.
Speed was between 46 and 53 mph.
Drivemode was ECO the whole time.

Yesterday and drove on the highway behind a truck and hat a calculated range of over 112 miles !
Speed was over 53 mph.
That is a boring method and also a little bit dangerous but saves a lot of energy....

Zero Motorcycles Forum | 2013+ / 2014 quick charger

« on: May 28, 2014, 10:31:28 PM »

Hello all,

i have a question regarding the optional Delta-Q Quickcharger.
I assume, that they are all simply switched in parallel by the y-cables from zero.
How does every charger know the amount of current or voltage to deliver ?
Or are they decoupled with diodes or something like that ?

Zero Motorcycles Forum | 2013+ / New SR Owner in Germany

« on: May 18, 2014, 11:34:54 AM »

Hello together ,
yesterday i got my brand new SR from my local dealer "orangebc" in Karlsruhe.
Thanks to Mr. Kloiber here for the delivery earlier than estimated!

The short ride from the dealer back to home with red numbers had been a really great feeling...
One challenge is remaining :
I have to find an insurance which covers that new bike ...
and then i will burn some kWh :-))

The bike should be taxfree in germany for the next 10 years, i read.

Best regards
Arno from blackforest in Germany

Here in Germany the electric smart is delivered with a battery you have to rent.
You do not own the battery but pay a certain sum each month depending on kilometers/year.
Starts at 60 Euro /month.
In case of selling the car the new owner has to enter this contract and is credit checked before.
I think, the most value part of the zero motorcycle is the lithium batteryyou have really bought.

Zero Motorcycles Forum | 2013+ / Re: Zero SR soon at black forrest in germany too

« on: April 11, 2014, 12:21:14 AM »

Hello all,
waiting for my sr i have spend some time to install my new "petrol station" for the bike.
2 outlets 220 volts 10 amps and one outlet 3 phases 32 amps for what ever will come.
Of course including a fault current circuit breaker and a digital electric meter with power display.
Maybe i buy a electro car in a few years but in germany you get no advancement from the government. Sad but one the other side you feel like a real pioneer :-))

Attached is a photo of my new "power socket for men"

Zero Motorcycles Forum | 2013+ / Zero SR soon at black forrest in germany too

« on: February 12, 2014, 12:22:09 AM »

Hello together,
my name is arno, i am 54 years old and living near karlsruhe in Germany. That is at the border of the black forrest.
Last year i rode my first electric bike, a zero s 2013 for 2 days.
I rent it from our local electric mobility dealer in karlsruhe (www.orangebc.com) and i was so embraced that i ordered a Zero SR . All my friends called me crazy, so much money, but i think it is worth this price.

In europe delivery will start at end of May so i have to wait a few month.
The area is ideal for regen braking , we have a lot of hills here.

Hope to read a lot of zero SR till may and i am happy about every youtube video (thanks to GNU here) to shorten the witing time for me :-))
