Airbus already has decided to make one design change to the original lithium ion battery system for the A350-900.
“So we put in a non-return valve so that if it blows out, it doesn’t go back in the other battery,” Champion said.
Weight savings is one of the key advantages gained by switching to lithium ion batteries, so Airbus hopes to install the batteries using an enclosure made of lighter materials than stainless steel.
"If you start to put a huge coffin around the battery system in place then you lose all the benefit of the lithium ion battery,” Champion said.
Boeing’s design includes 2 GS Yuasa-made batteries with 8 3.7V-cells each, storing a total of 72Ah of electrical power per battery.
“We are rather confident with our system because we have a different architecture than Boeing,” Champion said.
