BRD Motorcycles announced in its latest news on the development progress of RedShift electric motorcycles that after over a year and a half, it’s ready for commercialization of a new proprietary pack tech, which should be a “game changer for electrics“.

“In 2012, BRD decided to obsolete our state-of-the-art Li-Ion pack (the bright orange block seen in our development prototypes) and develop a new one. There was nothing wrong, necessarily, with the old pack – it was and still is at the forefront of pouch-cell-based packs like those in other high-performance electrics – but we saw an opportunity to create something significantly smaller, lighter, more robust, and safer.”

The new pack will store approximately a third more energy in the same mass of the previous version (increase from about 120 Wh/kg to over 160 Wh/kg).

“To nerd out for a second, conventional state of the art packs are presently hitting about 120Wh/kg TSL (total system level, i.e. the whole package: everything you need for safe power delivery and charging, including enclosures). BRD’s proprietary tech is over 160Wh/kg. On a bike like the RedShift with 5kWh of energy, that’s 10.5kg (23lbs) in savings, and a whole lot of packaging freedom to optimize center of gravity, ground clearance, and ergonomics. You can do the math for what that means on even larger packs. This isn’t laboratory tech. It will be in our bikes, under the most abusive conditions, next year.”

The battery pack upgrade is just one of many that are implemented by BRD, but maybe it’s the most significant. 160 Wh/kg is a high number that, for example, would lower the Nissan LEAF battery weight on the pack level from roughly 250 kg (551 lbs) to about 150 kg (330 lbs) or would alternatively enable increased energy and range.

BRD’s intention is to build the best MX and SX motorcycles, that just so happen to be electric.

You need to check your kg to pounds math!!!

Thanks.

It’s interesting how other players call “gamechanger” when in fact they only succeed in matching Tesla’s energy density. Goes to show how far Tesla is ahead of the pack. Sorry BRD, it was Tesla that changed the game. You guys are just catching up.

With the difference that BRD are using pouches and do not have much space to play with. It will be a game changer for the MX and SX class as soon as they can prove that they are capable of competing on equal terms with legacy bikes.
Something Zero, Quantia and Brammo to name just a few with MX attempts have not achieved yet.

Chris, the BRD pack is presently about 30% more energy dense than Tesla’s.

Correction… BRD is about 20% ahead. The Model S TSL density is about 135Wh/kg. It’s easy to confuse cell level densities (~240Wh/kg) with system level densities. Also, Tesla’s tech, which uses active liquid cooling, would be fairly difficult to implement on motorcycles and scooters.

What’s interesting about this was I made a comment about Mitsubishi i-MEV using a battery break though to get it up to 80 miles over the existing 62 miles with the same battery weight and mass but with more energy. If they are really going to build this here would support this up coming idea of existing EV’s raising their range. Also I like how they are saying they are raising it’s efficiently by a 1/3 which is more logical then some made up number of 500% or triple. This is over all a cool break though.

I like it too. It’s small changes like this that bring the tipping point closer and closer slowly but surely.
