787 Batteries and Chargers - Part 1

[RR_NDB]

Current control of dangerous batteries (787 design lacks it?)

I'm pretty sure there is, it would be inconceivable to connect an uncontrolled load (ie DC starter motor, etc) directly to any Li battery.

On inconceivable look to the battery picture. Certainly the design doesn´t control the CHARGING current independently in each cell.

This may explain BOTH INCIDENTS!

And on discharge control:

1) How you would design it? What kind of part to perform it?

2) We will learn soon to confirm. I suspect there is not this feature in 787 main battery (main one is my bigger concern)

This picture just shows the high current cell conections (strips) and the sensors wiring. There is no provision for independent cell charging!
