you said max. battery capacity usable is 80 percent. to overcome it you are multiplying it with 1.2 right? now find the 80% of multiplied value, you will get 96 which is less then we required.
solution: you must have to multiply with 1.25 to overcome 80%.
No, 1.2 is correct, let me explain you.
We need 750W if we consider 80% we will use means a 20% loss.
So 750*0.2 =150
So we need 150 extra so 750+150=900 W
@@nitin4171 if there is loss of 20%, then the figure of 750W should be divided by 80% to arrive at 100% value which is 937.5
1.25 is correct. If a battery has 80% efficiency and we need 750w after the loss in power, we need to find a battery wattage whose 80% = 750w.
80% of X = 750w
0.8 × X = 750w
X = 750w / 0.8
X = 937.5 w
937.5 w / 750 w = 1.25
750w × 1.25 = 937.5
please let us know calculation for different speeds i.e economy mode speed mode or high speed mode of bike
Thanks for educating people through Ur vedeo. It's worthy effort.

As per ur word 750w motor, 48v, 20ah battery, cover only 35kms. Travel by 35kmperhour speed ???
Range = AMP
Speed kese bada sakte he

Battery 48 volt 20ah ki ki hai lekin bakeup 15minut ka hi rahi to kya problem hai sakta hai ebyke hai
Thanks sir ! But agar jyada current denge toh motor aur baaki parts mein kuch problem toh nahi hoga kyuki motor mein ampere rating rating bhi hoti hai ... ?
Motor ki Amp rating aur battery ki AH rating alag alag hain. Ek 30ah ya 40ah ya 60ah ki battery se ek 750w ki motor 15/16 amp hi draw karegi. Ah ka matlab hai, ek hour main kitna ampere de sakte hai. Ek 60 ah ki battery agar 15amp ki motor chalati hai to 4 hours take chala saito hai.
Motor ko over volting se damage ho sakta hai. Aur low voltage main over current draw se damage ho sakte hai.
@@ElectricScootersJammu what is the solution of over volt and low volt over current damages?
Sir, does it gives the same 35km range for 24V 20Ah batteries??
Depend on speed speed is less in 24v battrey also motor ratings required with 24v
Thankyou sir for giving the information.
Sir is voltage matters while charging the battery?
Voltage will be constant according to the battery max voltage while the current must be constant according to the cell C rating. Higher rate of charging current will heat up the cells and damage the battery pack.
@@ElectricScootersJammu sir if iam using a device whice is producing
350 watt electric motor with 20 amp controller can be connected to 30 or 40 amp battery?
Very useful for me
Great video!!! But I cannot understand the explanation.
Could you suggest something for English speaker only?
Thank you. I'm researching the same math problem. I almost got it.😂
Great job
There are e v with 48v ,60v and 72v motors. What is the difference on performance.
मेरे पास oreva e स्कूटर है 250 watt मोटर, जिसमे 48v24ah laidacid बैटरी है।
मै 48v30ah lifo बैटरी डालना चाहता हु, कोई प्रॉब्लम तो नही होगी, 48v40ah lifo बैटरी भी डाल सकता हु क्या, कंपनी बुकलेट में 48v24ah बैटरी ही डालने लिखा है।

Very nice basic caclaulation. Thank you.
Nice sir
Sir for 48v 750W bldc motor i am using 48v 50Ah battery, my question is that charging or discharging current of battery is matter on motor current... Means chances of bust
Very useful information, one doubt, how should we calculate if we use 2 motors like two 48 v 650w hub motors
Why you use 35km/ hrs and how
Can I use use 60volt battery for 250watt electric scooter? What is the rule to follow that how much volt can I use for certain watt motor?
How to increase the speed of motor..? If we increase the speed or we drive in top speed, will the battery discharges quickly..?

Thanks
Very well explained. Thanks
This is for normal motor but if there are gears then range can increase or decrease substantially
Thank you sir. Very nice discussion.
Thanks
sir aur to sari baat apki thk h, magar ek baat samajh nahi aai agar aap range badhane ke liye ampere badhaoge to voh motor ki jo power hai 750 watt usse double ho jayegi to motor damage nahi ho jayega kya. For example 48v * 40ah =1920 Wh
Ampere nahin ampere hour. Ampere drawn by motor and ah of battery is different.
Hi. Sir 48v 750w gear removed motor use krne pr motor ko koi nuksaan to nhi hoga?

Good Explanation sir. Aap ne battery pack bataya, individual 4 x 60 amps batteries laganese range kya hoga.
sir jo aap bata rahe hai to jaise 4 battery hoti hai to har ek 20ah ki hone chaiye ya phir 4 battery ka add karke 20ah? means ek battery 5ah pleas tell me sir?
Series main voltage add hota hai. Ah value same rating hai
Please calculate how much Wh consumption per km. Please do it Sir
Sir aap bms supply karte ho kya.. pls reply kare
Nahin sir
How did you calculate Range from speed ?
U said :- 48v * 20ah = 960wh
And speed :- 35kmph = range 35km ?
Formula ?

सर आपने बैटरी की एफिशिएंसी के बारे में तो बता दिया लेकिन आपने मोटर की एफिशिएंसी के बारे में नहीं बताया मोटर की एफिशिएंसी को कैलकुलेट करना भी जरूरी है जैसे brushless hub motor जो आती है उसकी 93% के आसपास एफिशिएंसी होती है और जो आपने बाइक में मोटर लगाई है उसकी लगभग 85% एफिशिएंसी होती है , धन्यवाद ।
Maine jab max distance per hour bataya to motor efficiency, max rated load aur mechanical loss sab consider kar ke hi bataya hai.

Sir kya hum 48 volt ki battery ke sath 1000watt ka motor use kr skte hai??
Could you tell me, how much watt a electric scooter takes to go 1 km?
Can I use 1 crate battery
simple AH x 2 = kilometer range right
20 AH X 2 = 40 km range
Depends on motor ratings.
