This project covers the implementation of the power systems on Bearacuda, the power consumption of major components, fusing and voltage regulation. The power system for Bearacuda may include two sets of rechargeable batteries: one 24V set for the propulsion, and one 12V set for the rest of the electrical systems. Another option endorsed by the PhysE team is to use two batteries of the same voltage. This would allow more more flexibility in battery purchasing.

Charge Capacity: 5Ah
Weight: 613g
Voltage: 18.5V
Notes: dimensions 42x48x160 [mm], charge available from same site for $130, purchase of a LiPo charging bag is recommended
Information on the handling, storage, and transportation of LiPo Batteries is available in the Primer Document
Must handle with caution.
Voltage Regulator
Notes: Takes a regulated 12V in and distributes it to an ATX power array (3.3V 5V -/+12V)
- New Voltage Regulator:
A new voltage regulator must be acquired, as the 100 W Vicor regulator we currently have will not be able to provide power for all the electronics once the embedded computer is installed. A 150 W regulator would probably be sufficient but to maintain a safe margin, a 200 W supply would be preferred. A 200 W Vicor is being ordered for testing purposes but it would be preferable if we could develop our own as well. Anybody interested in this project should contact Darrel. - DarrelRoss 07:58, 21 September 2008 (MDT)
Battery Charger
Notes: Can charge, discharge, and balance. 1 to 6 LiPo Cells charging capability.
The battery charger purchased requires a 12V/10A DC supply to charge from and has been purchased.
Other Components
- LipoSac
Bearacuda Power Consumption:
Embedded Computer: 40-50W
Roboteq AX500: ~3*6W
MC68332: ~2*0.455W
Sensor array: ~5W
P = 50W + 18W + 2 * 0.455W + 5W = 74W
