Williams Advanced Engineering’s Adaptive Multi-Chem technology brings together the company’s knowledge from a wide variety of projects, including four seasons as the sole battery supplier to FIA Formula E and multiple cutting edge vehicle programmes. Adaptive Multi-Chem technology enables reduced mass and volume, thus increased energy density for a target power density within motorsport, hypercar and electrified flight applications.
Increasing the energy and power density of batteries is widely regarded as one of electrification’s greatest challenges. With the industry ramping up production of electric and hybrid vehicles, there is significant demand for new battery technologies. Manufacturers are usually faced with a compromise between energy and power density as they try to minimise the size and weight of battery packs for a target performance level. Williams Advanced Engineering’s Adaptive Multi-Chem technology provides the best of both worlds. It uses a state-of-the-art, bi-directional DC/DC converter to deliver high energy and high power density in a single pack.
Use of Adaptive Multi-Chem technology enables a 37 percent increase in energy density for a target power density. The system is highly adaptable, with semi-independent sizing of energy and power cells through the use of scalable blocks. A compact thermal management system is able to provide sufficient cooling without unnecessary bulk, improving packaging. Adaptive Multi-Chem will allow the use of novel, ultra-high energy and power dense cell technologies in a variety of high performance applications including motorsport, performance cars and aerospace.
A demonstrator module was first revealed at the Low Carbon Vehicle Show in September 2019. Peak power, continuous power and stored energy of the module can be tailored to individual requirement. The unit showcased has a total stored energy of 60kWh, with a core battery mass of 345kg. Peak deployment power is 550kW (20 second pulse), and peak regeneration power is 550kW (10 second pulse). The module is encased in Williams Advanced Engineering’s patent-pending lightweighting technology, the revolutionary 223TMcomposite manufacturing process.
