Energy Density Increased By 37% Williams Introduces New Battery Technology

- Oct 23, 2019-

Foreign media reported that Williams Advanced Engineering (hereinafter referred to as Williams), a subsidiary of F1's veteran Williams, announced the development of a new lithium-ion battery technology that can reduce the weight of automotive battery packs by 30%. Increase by 37%. It will also showcase its latest low-carbon vehicle technology at the Cenex LCV2019 show.

It is understood that this innovation means that batteries of the same weight as conventional devices can provide longer cruising range or provide higher power without affecting power.

Williams plans to use two different types of cells, arranged in two separate blocks within the module, mainly using the 21700 cylindrical battery produced by SDI and the soft-pack battery provided by the universal A123 system.

According to the design, the soft pack battery provides the fast release energy required for strong acceleration, and when the energy is exhausted, the energy is again obtained from the Samsung battery. Each battery module has its own integrated bidirectional DC/DC converter that controls the energy transfer process between the two types of batteries.

At the same time, all control software is written internally by WAE, and each module has a separate liquid cooling system.

Paul McNamara, Senior Engineering and Technology Director of Williams, explained that we are the sole battery supplier for FIA Formula E and have extensive experience in battery technology and have participated in the development and design of several electric vehicle projects. However, due to the increased design complexity and integrated electronics of the battery module, the cost will be higher than that of the conventional module, but it is expected to reduce the cost as the number of uses increases.

Williams is part of the British Williams Group, providing services in the fields of technology and engineering, bringing technological innovation to mainstream industries such as automotive, motorsport, transportation, energy and other industries. His expertise includes advanced power technology and the award-winning top-of-the-line electric vehicle power battery technology from the four Formula E.

Williams has already cooperated with many top car companies in the world and has become a battery supplier for many car companies.

In June 2013, Williams won the contract for the world's first pure electric car race, the FIA Electric Formula, to provide battery packs for a total of 40 racing cars.

In 2014, Williams and the US energy storage company XALT Energy reached a partnership agreement to provide lithium-ion batteries for the FIA's electric formula vehicles, and will conduct a series of in-depth cooperation around lithium-ion battery technology. XALT Energy will supply lithium-ion batteries for the battery packs of participating vehicles, and Williams offers advanced lithium battery pack development technology.

In 2018, British luxury sports car manufacturer Aston Martin announced the official map and details of its first pure electric sports car Rapide E. The pure electric super-running limited to 155 units will be cooperated with Williams Advanced Engineering Company (WAE) and is expected to be delivered by the end of 2019.

The Rapide E is powered by a 65 kWh battery pack consisting of 5,600 cylindrical lithium batteries. The Rapide E has a combined cruising range of 200 miles (321 km) under the WLTP test, and the 800 V battery system means the model can be quickly charged. With 100 kW fast charging technology, you can drive 300 miles an hour.

In January 2019, the British Lotus and Williams reached a cooperation to develop a new plug-in hybrid sports car, Williams mainly provides battery system related technology.

In May 2019, Williams announced that it will supply batteries for the E-TCR series of electric motorhomes scheduled to be launched in 2020.
