Recycling or refurbishing of lithium-ion batteries is crucial in tackling the challenges of climate change and air pollution. While there is the demand for batteries to have more capacity and longer life cycles, lots of time and investment are also required to dismantle and recycle batteries. Precious metal, such as Lithium, needs to be saved while batteries need to be renewable as well.
A start-up company has developed a Battery Management System (BMS) circuit, software and process to refurbish small lithium-ion batteries used in wheelchairs, laptops, tablets, drones and more. The technology enables the consumer to achieve significant cost savings and environmental benefits compared to buying new batteries or using other battery recycling methods, with a wide support for different types of batteries from various battery manufacturers.
The company is seeking potential partners in Singapore to collaborate through a licensing agreement, whereby the know-how and the process of battery refurbishing will be transferred to the partner.
The technology provider is the proprietary owner of a BMS circuit, software and process. The new BMS CPU is interfaced with the existing BMS to control the normal charging / discharging operations. It is capable to access battery health information from the existing battery BMS, and recalibrate the full charge capacity for each cells in the refurbished battery pack, so that it can deliver the correct rated power. The full charge capacity is an estimate of the battery's state of health (SOH) based on proprietary software loaded in the BMS CPU. The technology provider and their partner have worked with more than 3000 types of BMS / batteries to date. The battery refurbishing process consists of the following steps:
Refurbished batteries are estimated to be up to 30% cheaper than buying new batteries.
The battery recycling and refreshing technology is applicable for small and micro e-mobility devices such as wheelchairs, e-bikes and e-scooters, electric devices, robots, laptops, tablets, power tools, drones and more manufactured by Japanese and South Korean companies.
Demand for battery refresh or recycling continues to increase significantly. According to a report by Reports and Data (US) in 2019, the world market cap for all battery recycling is 4B USD in 2019. The market for this technology's targets is 1B USD, which is estimated to be 4B USD in 2026. The current target market is battery refreshing for smaller e-mobility (drones, e-scooters, e-bikes, wheelchairs), electric devices (tools, PC), robots, and more with plans to apply Machine Learning and IoT in the know-how in the long term to make the technology more efficient and scalable.
The benefits of the technology include:
