If they're lagging in the EV department due to lack of funds, purchasing a startup like this won't change that. Bollinger probably designed almost none of the core "EV" stuff - motor drivers, motors, charging circuitry etc. They couldn't afford to. They've almost certainly bought it off the shelf from one of the many automotive OEMs. Chrysler could do the same.
It doesn't help that FCA insists on doing the bare legal-minimum wrt to EVs. Their executive team does not see any value in EVs, they are literally just a cost of doing business for FCA.
