Battery power explained..                        


New 36 volt 10 amp batteryOkay.  You have decided to buy an electric bike, hopefully from Silver E Riders and you have tried out some other e-bikes, but what do volts, amp hours, watt hours mean?  Well I aim to answer some of these questions for you here in a language you can hopefully understand.

The terminology for electric bike batteries can seem a little foreign at first but I think the following will relate it to some typical car terms that may make more sense to you.

Volts (V) = Horsepower!

More Volts… More Horsepower

The more amp hours you have, the more range you will get with your electric bike and the better it will be in uphills.

The typical battery is 36V on most e-bikes with some at 24V and some at 48V.  The electric bike manufacturers spec these because they provide a good power to cost ratio.

 

Tyre Pressures.

What are your tyre pressures?  Lower pressures = less range.   There is a nice balance between too high a pressure (uncomfortable to ride) and too low a pressure (poor efficiency).  50-60 psi is a good pressure range for street riding for most types of electric bikes.

Watt Hours?

Basically it is the combination of the volts and amp hours to give you the total energy in the battery pack. You may see this in the specifications for an electric bicycle.

Volts x Amp-hours = the amount of energy in the battery, or watt hours (WH).  For example 36volt X 10amp = 360 watt hours.

Electric Bike Battery Specifications and cost per charge.

The first thing you'll need to measure for these calculations is the Voltage and Current rating for your electric bike battery. These are usually featured on the front of the battery. If you're not sure, check the owner's manual. A rough average for an electric bike battery like one from Silver E Riders is 36 volts and 10 Amp-Hours. This is a Lithium-based electric bike running for approximately 25 miles on a single battery charge.

Okay, now to calculate the Kilowatt-hours (kWh) of your electric bike. Simply multiply those two numbers together and divide by 1000:

36 volts x 10 Amp-hours / 1000 = 0.36 kWh

This means that it takes about 0.36 kW to charge an electric bike for one hour. In most cases, an electric bike will need to charge for about 4 to 5 hours to fully charged condition, so let's say the total consumption for a complete charge cycle is:

5 hrs. x 0.36 = 1.8 kWh

So there we are, simply multiply 1.8kWh by your electricity tariff and there you go.

It is much cheaper to run an electric bike, even in the most extreme circumstances. The cost to charge the bike is hardly noticed on a monthly scale, and is far cheaper than running a car on petrol or diesel for a month. Want to save some money?

Battery information and care….

One of the most important items on an electric bike is the power source. i.e. the battery, like any battery, be it a mobile phone, laptop, power tool etc. they require looking after to provide you many years of reliable service……….

Battery life and maintenance….

Electric bicycle suppliers and manufactures quote a number of “charge cycles” when describing the life of your battery… On average this number is about 1000 charge cycles. This is not always the case as the way you look after your battery is most important… The battery must be charged at least one a month for maximum life span. Rechargeable Lithium Batteries like to be used regularly. Batteries used every day are more likely to last more charge cycles than one used less frequently.

It cannot be stressed more strongly.  Charge your Lithium Battery at least one a month.

All batteries slowly deteriorate in time, whether you use them or not, so how do I get the best from my Lithium Battery?

·         Store your battery between 5 degrees Centigrade and 20 degrees Centigrade. (41degrees F and 68 degrees F)

·         Store in a cool and dry environment out of direct sunlight. The garage is a good place.

·         If your Lithium Batteries are to be stored for an extended period, lets say during wintertime. It is imperative you charge your battery prior to storage and then charge the battery once a month to help prevent any deterioration in the cells.

·         Routinely check the batteries charge status.

·         Always follow the manufacturers instructions provided with your battery.

ALL batteries have a life span. Your Lithium Battery should, if you follow the instruction above last you a minimum of between 3 and 5 years.

Disposal of your battery at the end of its life should be disposed of responsibly.

Most Local Authorities offer recycling and disposal facilities.

Or if you prefer please return your battery to Silver E Riders.
