Solar Energy Storage System at Paris Auto Show

energy storage

AllCell Technologies has designed and developed for Matra Manufacturing Services the Matra Solar Flow-R energy storage system (ESS). The system stores solar energy in an array of high energy lithium-ion battery modules using AllCell’s exclusive, patented PCM technology.

Electric scooter and light electric vehicle drivers can swap depleted battery modules from their vehicles with fully charged battery modules or charge the vehicle directly through the power plugs located on the front panel of the ESS. An extra option allows the solar grid-integrated system to supply energy to utility customers during high-rate and peak demand periods, reducing energy costs and increasing renewable energy usage.

The cornerstone of the system is AllCell’s 1.44 kWh (48.1 V, 30 Ah) high energy lithium-ion battery pack. The 8 kg module has an industry best energy density of 180 Wh/kg, made possible by AllCell’s proprietary phase change material (PCM) technology that surrounds each cell in the pack to provide optimal heat management and safety control. In addition, PCM’s unique thermal properties extend the life of the battery, allow for use in extreme climates (45°C+), and enhance the battery’s power (1/2 hour full discharge versus 1 hour discharge industry standard for high energy cells).

The Matra Solar Flow-R enables consumers to tap into the previously unutilized value of their batteries. Typically end-of-service-life for most batteries comes when the battery‘s capacity has degraded beyond the useful drive range in an electric scooter or light electric vehicle and the battery is either recycled or thrown away. The Matra Solar Flow-R uses new and recycled battery modules, extending the useful life of the battery packs and improving the economics for consumers. In addition to controlling energy flow between modules, the smart electronics optimizes the flow between the solar panels, modules, and grid to increase renewable energy usage and minimize cost.
