During setup, place 4 SpeedCharger tokens per player in a supply next to the Game board. Each player receives a Charging board which is placed next to their Player board.
When working Shifts in R&D (or indirectly through Administration), you may spend 1 Shift to take a SpeedCharger token from the supply and place it on a space of your choice on your Charging board. From now on, the covered bonus is active for the rest of the game. Also, at the end of the game, each Charger token is worth 1 PP for each Car in your garages.
For example: If you have 3 cars and 4 SpeedCharger tokens, you score 12 PP.
You can only take one SpeedCharger per turn.

The Bonuses when played in...

R&D - Once per turn, you can upgrade 1 Design with a Car Part from the supply.
Assembly - You may ignore the restriction of having to provide upgraded parts first.
Logistics - You bank 2 Shifts instead of 1 when placing a Kanban card.
Design - When you take a Design from the Central Design Stack, gain 1 Book.
Administration - When working in Administration, you receive 1 extra Shift.
