Giving an overview of the power architecture …
↓↓↓ Complete description, time index and links below ↓↓↓

Last time we’ve revamped the temperature measurement to use the ATmega4809’s temperature sensor (link below). Since I didn’t make any headway regarding the mechanical design, I thought I give you an overview of the power architecture.

First we talk about what is meant by power architecture (get power from the batteries to the motors), what the context is (type of boat), and what constraints there are.

00:00 Intro – let’s talk about the power architecture
01:15 Power – from batteries to motors with constraints
04:30 Method – to evaluate different solution
07:54 Tangent – current and cable cross section (math!)
12:33 12V system – needs lots of copper
15:31 24V system 1 – simple, but inconvenient
17:06 24V system 2 – more convenient, but dangerous
19:25 24V system 3 – over-engineered, but nice
21:31 Question – let me know what you think
22:37 Wrap-up – sorry, more delays ahead, bye
