The reseach conducted in Lithium highlighted that a change in lithium extraction, even though possible, was not feasible in the short period. The best and most effective solution is to change the way we implement power in our products.

BM1 Power-Delivery (100W) mainboard powered by IP2368 IC

The battery module system is my vision of change. It is a system where portable power is standardized and common to all products: from portable tools, to household appliances and power-hungry applications. A single fast swappable, repairable, battery pack for a multitude of devices.

This was possible thanks to the power delivery protocol. USB PD (Power Delivery) is a specification or industry standard for managing high power […]. It provides more flexible data transfer and power delivery by enabling maximum USB functionality over a single cable. (Satechi.net, 2021) The power delivery protocol enables the use of a single standard charger / connector for all our electronic devices, reducing the need for multiple and often proprietary power adapters.

Project’s DNA

The BM-Ecosystem

More freedom, less engineering constraits: the BM-Ecosystem consists of a series of products designed to be powered by BM modules.

Electronic Minimalism

Inside every BM compatible product the only component needed to deliver power is the decoy PCB which through the Power-Delivery protocol comunicates with the batteries and sends a request matching applicance’s voltage requirements. Compared to a traditional battery powered product there is no need to have in-object battery protection, voltage regulation or transformers.

A common ground

The shape of the battery packs is dictated by the disposition of the internal components.
The mechanical importance of this form relies on the fact that is linking ground between the battery packs and the object. The basic shape comes from an offset of the internal cells footprint and a the connection between the vertical quadrants.Thjs creates enough room to protect the cells while leaving space for the Battery Management System and Power Delivery PCBs.

The battery modules can vary in height, but will keep the same footprint. This creates a common ground of compatability between all the appliances and enables scaling the battery capacity with height.

The Collection

The BM-Speaker

The BM-Speaker is a 50w portable Bluetooth speaker that is powered and designed to work with the battery modules.

The speaker features minimal electronic components, and enables when connected to a mains plug, to recharge the modules themselves. The device acts both as a powered device, and as a dock.

The BM-Torch

The BM-Torch is a small torch that plugs on top of the battery modules and poweres through the type-c connector.

The modules features a 3W high-power Nichia LED, a custom made aluminium heatsink and small led driver ic.

BM-BOARD

70 km/h Max Speed

30 km Range

0 to 50 in 3.5 seconds

~5Kw Max Power Output

The BM-BOARD is the bet I took when I began developing this system. In order to show the full capabilities of the battery modules I committed in finding an application which could, in a single glance, show that the project is not just a gimmic. An application without compromises that takes my idea to the extreme.

The BM-BOARD is an electric longboard powered by the BM-MODULES. With dual 6354 BLDC motors, a 200A ESC, 18:36 gearing and a peak output power of nearly 5 KiloWatts delivers a true breathtaking experience with the convenience and perks of the quick-swappable battery modules.

The board is fully customizable via the VESC app whic enables to limit the output power to comply to the current electric-transportation legislations and extend the range. On the fully unlocked track-mode, thanks to the dual motor configuration and a reduced weight of only 9kg, enables a breath taking 0-50 acceleration of only 3.5 seconds and a maximum speed of 70km/h.
