Flow cell battery in a (kind of) practical car


Credit: La Vecchia/Green Car Reports

Flow cells can be recharged by connecting to a charger or by replacing the liquid electrolyte. These, & other characterisics, make them very attractive for automotive applications. To date, size & weight have restricted flow cells to stationary applications.

La Vecchia claim to have overcome these problems in their Quant e-Sportlimousine, revealed at the Geneva Motor Show. Claims of Tesla levels of range & performance have yet to be demonstrated, but plans for 4 prototypes for real world testing should answer the questions which their very big claims imply.
