SUMMARY

A 48V, 32Amp lithium-ion battery can effectively operate two 36V, 750W hub motors, as the voltage is compatible. The motors will draw current based on their load and efficiency, and while the nominal speed may be slightly reduced due to the higher voltage, the overall performance should remain satisfactory. The battery's discharge time will be extended due to the increased voltage, allowing for longer operation at nominal speeds.

PREREQUISITES
  • Understanding of electric motor specifications, particularly voltage and power ratings.
  • Knowledge of battery characteristics, specifically lithium-ion battery voltage and amp-hour ratings.
  • Familiarity with electric vehicle design principles, including motor control and speed regulation.
  • Basic electrical engineering concepts, including current draw and efficiency calculations.
NEXT STEPS
  • Research "DC motor current draw calculations" to understand how to estimate current consumption at different speeds.
  • Learn about "motor controller options for hub motors" to effectively manage speed and torque.
  • Investigate "battery management systems for lithium-ion batteries" to ensure safe operation and longevity.
  • Explore "electric vehicle range estimation techniques" to calculate expected run time at nominal speeds.
USEFUL FOR

Electric vehicle enthusiasts, automotive engineers, and hobbyists involved in electric car projects who are looking to optimize motor performance and battery usage.

Hi,
I am doing a project of making an electric car while using two DC Hub motors of 36V (750W power) each, one on each rare wheel. I intend to use a single Lithium ion battery of 48V and 32 Amph to operate both the hub motors.

Please tell me 'can a 48V & 32Amp Battery operate Two Hub Motors of 36V each (750W)?'
If yes then can it perform efficiently (i.e., battery discharge time is increased)?
Will it reduce the nominal speed of the motors?
 
Engineering news on Phys.org
Assuming top speed of your car is when the motors are driven at 36 V, how much current will they consume at that voltage?

How much voltage and current will it consume at nominal speed and current?

How will you control the car's speed?

How long do you need the car to run at the nominal operating speed?
