FreeWire Mobi Charger Puts Nissan LEAF Batteries To Use In Mobile Charging Unit (w/video)

The charging station business hasn’t even matured, yet start-up FreeWire wants to shake the whole business up.

Forget about stationary charging stations, now they can move and will come to charge your car autonomously. At least this is the FreeWire’s vision.

Everything begins with old Nissan LEAF battery modules (about 10 kWh total), which find a second life in a mobile energy storage system. FreeWire adds a J1772 EVSE interface and ends up with the Mobi Charger.

According to FreeWire, several such devices could serve electric cars in the parking lot without worries that a charging spot will be occupied by an ICE car or an already charged EV.

Ultimately, the Mobi Charger battery pack probably will be a few times larger (like 48 kWh) and offer DC charging too. When there is no need for charging, Mobi Charger may even become an ESS in smart grid system.

However, there is one big question. How much it will cost?

10 kWh hardly seems practical. The average Level 2 public charge session is just under an hour provide ~6 kWh of charge. While the mobi-charge doesn’t need to be attached to the grid while providing a charge, it will need to recharge between charging sessions.

Not seeing a business model that offers value at a price-point to cover the investment in additional mobi hardware.

Beyond the mobi-charger concept, I do see business models were battery storage adds value to charging sessions. These use cases tend to relate to DCFC to reducing demand billing related to high power peaks. Another use-case is with solar to slowly accumulate energy in storage, but allow DCFC to quickly charge a vehicle.

To answer Mark’s question, it has to cost a few thousand more than the battery pack.

Interesting idea, perhaps more as an electron gas can device if employees need a bit more juice to get home.

A cool improvement would be to couple it with Elon’s new automatic charging proboscis. It could autonomously go around and charge vehicles whilst everyone was at work.

Another great use for Leaf Modules.

They also make a great energy storage system for Solar as this inside EV’s article points out:

Thanks for the great article, Mark! Please reach out to me, as I’d love to tell you more about our vision.

Also, we’ve already released a 48kWh version with dual Level 2 (J1772) and Level 3 (CHAdeMO) output.

Meh…. like Brian said 10kwh charging is hardly useable for a full recharge especially if you have someone that pull in with say less than half of the battery of a LEAF available, the portable device will not be able to recharge back to 100%, perhaps just 80%, clearly not a solution if you require a full battery to make it home. The portable device still has to be called upon to plug up to the car, this delivery will take time and must still be manually connected/disconnected to the vehicle, so you’re not saving any time there. How do you handle if a parking lot is say covered in ice or snow? If I pull into a charging parking space where there is a stationary charging device, I simply open my charging port, connect the charger and initiate a session. With the wheels on these portable devices they obviously would have difficulty navigating obstacles to get to the requesting individual. Not to mention, you’re going to be sitting in your car, in the cold, waiting for some mobile charger to show up. Then there’s also the time needed to RECHARGE the mobile chargers! The charging of the mobile chargers… Read more »
