The deal has added to a rally in the Nasdaq listed shares in Tritium, which have risen above $US10 recently, but was sitting below $US9 at the end of last week.

The initial order from BP was for 1000 units for the UK, Australia and New Zealand markets and Tritium said this was a “step-change” in the relationship.

Tritium’s chief executive Jane Hunter said the electrification of transport was entering an “incredible era” when major companies like BP were providing critical support to the transition to cleaner energy.

“We’re thrilled to be working with BP to create greater global access to fast charging in support of their mission to become a net zero company by 2050 and to be a leader in helping the world get to net zero.”

Tritium listed on the Nasdaq earlier this year and shares reached a high of $US15.70 after Hunter shared a stage with US President Joe Biden to announce the opening of a manufacturing centre in the US.

The company was founded in Brisbane in 2001 and designs and manufactures hardware and software for DC fast-charging of electric vehicles.
