You have questions about our products and our company? Then you have come to the right place!
Our FAQ picks up those questions often asked and beyond that we would like to answer further questions all around e-bike batteries and the basics of the lithium-ion technology.
Charging a E-Bike Vision Battery
Does my existing charger work with the replaced battery?
Yes, with one exception. All E-Bike Vision Batteries can be charged with the original charger. The E-Bike Vision Battery for the Panasonic 36V drive system is the only exception. In this case you need to buy an E-Bike Vision charger.
Do the Akku Vision (quick) charging units work with original batteries?
No, the (quick) charging units from Akku Vision are only suitable for charging replacement Akku Vision batteries.
Can I connect the original charger to the external charging socket?
No. Most manufacturers of e-bike drive systems use proprietary plug connections and restrict the max. charging current of the battery. Only the E-Bike Vision chargers allow a charging of E-Bike Vision Batteries via additional charging sockets. If you do not own an E-Bike Vision charger you can use the original charger for charging (for the exception see E-Bike Vision Battery Panasonic 36V).
Do I need a new charger to utilise the quick charging?
Yes. In order to quick-charge the E-Bike Vision Battery you will need our quick charger which can be connected to the additional external charging socket. [Go to Chargers]
How long do I have to charge the E-Bike Vision Battery?
You can work that out yourself very quickly. If the E-Bike Vision Battery has a capacity of 17 Ah, and you want to charge the empty battery with a 4 A charger to 100%, you will need approx. 4.5 hours.
Battery capacity: charging current = approx. charging time
17 Ah : 4 A = 4.25 h 17 Ah : 7 A = 2.5 h
The reason why we use the term ‘approx.‘ here, has to do with the charging procedure CC/CV. To start with a constant current (CC) is used, towards the end, however, only a constant voltage (CV) is used. During the CV-phase the current reduces very much and the simple method of calculation becomes rather inaccurate at this point. Therefore, about half an hour is added.
Is there a memory effect?
No. The memory effect known from the past and older battery technologies, does not exist with the modern lithium-ion batteries. You are safe to interrupt the process of charging in-between.
It is, however, recommended to fully charge the rechargeable battery at the beginning and also following a prolonged pause and subsequently empty it completely. These 1 – 2 recommended full cycles only serve to calibrate the gas gauge (establish the capacity) exclusively.
Do I always have to fully charge the E-Bike Vision Battery?
No. You can interrupt the charging process in-between. That does not damage the E-Bike Vision Battery.
How much is the charging of a E-Bike Vision Battery?
Presuming that the electricity price is about 30Cent/kWh and you use a 612 Wh (0.612 kWh) E-Bike Vision Battery, one charging process will cost you 18.36 Cent.
612 Wh = 0.612 kWh = 18.66 Cent
468 Wh = 0.468 kWh = 14.04 Cent
Presuming you commute to work daily and the E-Bike Vision Battery 612 Wh lasts three days before you have to fully charge it again – you would use about 45 kWh per year and that will cost you 13.50 EUR per year.
