I have searched the bowels of the internet for an answer to this question. If I already have a motor, how do I identify what battery(ies) will be sufficient to power it.
For instance, this is one of the motors I am interested in:
http://www.jobymotors.com/public/views/pages/products.php
- Construction: inrunner
- Nominal Voltage: 40-450V
- Poles: 22
- Nominal RPM: 6000
- Maximum RPM: 9000
- Diameter: 154mm
- Mass: 1800g
- Length: 53.1mm
- Continuous Torque: 13N-m
- Continuous Shaft Power at Nominal RPM: 8.2kW
- Peak Torque: 20N-m
- Peak Shaft Power at Nominal RPM (15s): 12.6kW
And here is a battery I am looking at:
http://www.evwest.com/catalog/product_info.php?cPath=4&products_id=263
- Capacity: 160Ah
- Height: 279 mm (10.98 inch)
- Width: 71 mm (2.80 inch)
- Length: 182 mm (7.16 inch)
- Weight: 5.6kg (12.35 lbs)
- Bolt Size: M8
- Voltage nominal: 3.2V
- Charge voltage cut-off: 3.6V
- Discharging cut-off: 2.5V
- Life Cycle (0.3c Charging-Discharging, 80%DOD): 2000
- Maximum Discharging Current (10 sec.):8C - 1280 Amps
It seems like it may be able to supply more than sufficient capacity and current, but the voltage is tiny compared to that of the motor, can someone please help explain how I can know if a battery will be sufficient for a motor and what are the important specs I should be looking for?
Thank you very much,
Leland
