New Energy Battery Refurbishment Case Description

Are retired EV batteries a threat to the environment?

In line with the global target in decarbonising the transportation sector and the noticeable increase of new electric vehicles (EV) owners, concerns are raised regarding the expected quantity of Retired EV Batteries (REVB) exposed to the environment when they reach 70–80% of their original capacity.

How are non reusable batteries recycled?

Non-reusable batteries and scraps generated during production are recycled. Raw battery materials can be extracted by grinding and dissolving them. Then, through the resource circulation system, some of the extracted materials are reinjected into the production stage of cathode materials.

How can a battery management system improve the performance of residential buildings?

A BMS was developed to control the charging and discharging process of the battery to increase its Remaining Useful Life (RUL) and reduce the rate of degradation. Results have shown promising performance of the proposed system with appropriate controlling strategies to provide energy for the residential building.

How many reusable batteries are there in 2021?

In 2021, Bloomberg NEF, a research provider monitoring the transformation of the energy sector, predicted that there would be more than 110 GWh of reusable used batteries, also called “end-of-life batteries”, in the global market by 2032 – that’s enough to power 11 million pure EVs.

What is the UL 1974 standard for repurposing lithium ion batteries?

VI. UL 1974 Standard for Evaluation for Repurposing Batteries • National standard for both the US and Canada. Advancing Refurbishment and Direct Recycling Methods. Proprietary technology to recycle lithium-ion batteries, recovering metals such as cobalt, copper and lithium. Approved Lithium ion battery recycler by NEA since December 2017.

Do EV batteries have a second life?

An experimental methodology was designed and conducted by to evaluate the second life performance of seven different EV battery kinds with alternative characteristics using a duty cycle that emulates the behaviour of grid energy arbitrage service, where batteries are exposed to deep discharge cycles at 4h, 2h and 1h constant power rates.
