2d-life use: Audi e-tron Battery Modules Energy Electrify Rickshaws in India

  • Audi Environmental Basis is going into 3rd challenge section with non-profit start-up Nunam: Battery modules from Audi e-tron check cars electrify rickshaws in India
  • Goal crew, ladies: Rickshaws to permit financial participation and supply a protected method of transportation
  • Timo Engler Head of Coaching Car Engineering / Logistics on the Neckarsulm website online: “Our group of trainees advantages from the intercultural change, the Nunam group from our expertise in battery electronics, charging time, and design – the result’s a tuk-tuk with Audi’s DNA.”

A moment existence for electrical automobile batteries: The German–Indian start-up Nunam is bringing 3 electrical rickshaws to the roads of India. They’re powered through used batteries taken from check cars within the Audi e-tron check fleet. The purpose of the challenge is to discover how modules made with high-voltage batteries can also be reused after their automobile existence cycle and change into a viable second-life use case. The challenge additionally goals to reinforce process alternatives for girls in India specifically: They are going to be supplied with the e-rickshaws to move their items. The non-profit start-up based totally in Berlin and Bangalore is funded through the Audi Environmental Basis. Nunam advanced the 3 prototypes in collaboration with the educational group at Audi’s Neckarsulm website online, which in flip advantages from the in depth intercultural change. That is the primary joint challenge between each AUDI AG and the Audi Environmental Basis along with Nunam.

The e-rickshaws powered through second-life batteries are scheduled to hit the roads in India for the primary time in a pilot challenge in early 2023. There they’re going to be made to be had to a non-profit group. Girls specifically will be capable of use the all-electric rickshaws to move their items to marketplace for sale, all with out the desire for intermediaries. The e-rickshaws are powered through used battery modules that spent their first existence in an Audi e-tron. “The outdated batteries are nonetheless extraordinarily robust,” says Nunam cofounder Prodip Chatterjee. “When used correctly, second-life batteries will have an enormous have an effect on, serving to other people in difficult existence scenarios earn an source of revenue and acquire financial independence – the whole thing in a sustainable method.”

The beginning-up’s number one function is to broaden techniques to make use of outdated batteries as second-life energy garage methods, thus each extending their lives and the use of sources extra successfully.

“Automotive batteries are designed to final the lifetime of the automobile. However even after their preliminary use in a automobile, they nonetheless have a large number of their energy,” Chatterjee explains. “For cars with decrease vary and tool necessities, in addition to decrease total weight, they’re extraordinarily promising. In our second-life challenge, we reuse batteries from electrical automobiles in electrical cars; chances are you’ll name it electrical mobility ‘lite’. On this method, we’re looking for out how a lot energy the batteries can nonetheless supply on this hard use case.”

“Reusing e-waste”

“E-rickshaws have a perfect eco-efficiency,” says 31-year-old Chatterjee. With a high-energy-density battery and relatively low automobile weight, the electrical motor doesn’t need to be in particular robust, since rickshaw drivers in India shuttle neither rapid nor some distance. Whilst electrically powered rickshaws aren’t an unusual sight at the roads of the subcontinent as of late, they steadily run on lead-acid batteries, that have a quite quick provider existence and are steadily no longer disposed of correctly.

On the similar time, rickshaw drivers rate their cars basically with public grid electrical energy, which has a excessive percentage of coal-fired energy in India. Nunam has an answer for this as neatly: The e-rickshaws rate the use of energy from sun charging stations. The sun panels are positioned at the roofs of the native spouse’s premises. Throughout the day, daylight fees an e-tron battery, which acts a buffer garage unit. And within the night time, the facility is handed directly to the rickshaws. This manner makes native riding in large part carbon-free. The upshot: The electrical rickshaws can be utilized all through the day – and nonetheless be charged with inexperienced energy throughout the night time and night time. In India, the place the solar shines all yr spherical, hanging sun panels at the roof is a no brainer. The charging station used to be additionally advanced internally.

Nunam regularly displays the e-rickshaws’ efficiency and vary. The social marketers make the entire e-rickshaw knowledge they gather to be had to possible imitators at the open-source platform https://circularbattery.org/. In reality, imitation is expressly inspired. “Tasks like the only pioneered through Nunam are had to in finding new use instances for e-waste. Now not simplest in India, however international. So Nunam stocks its wisdom to inspire extra projects to broaden merchandise with second-life elements that may pressure the eco-social revolution ahead,” says Audi Environmental Basis Director Rüdiger Recknagel. The Basis has been investment Nunam since 2019.

Additionally, after the battery has spent its first existence in an Audi e-tron and its moment in an e-rickshaw, it has no longer essentially reached the top of the street. In a 3rd step, the batteries’ ultimate energy could be used for desk bound packages similar to LED lighting fixtures. “We need to get the whole thing conceivable out of every battery prior to recycling,” says cofounder Prodip Chatterjee.

In the longer term, electrical mobility and solar power can assist scale back India’s dependence on fossil fuels similar to coal, scale back the massive quantity of exhaust emissions on India’s roads, and supply other people with a competent energy provide. Rüdiger Recknagel feedback: “In some ways, this challenge is pointing the best way ahead.”

“Anchoring sustainability in coaching early on”

Along with the rickshaws meant for street use in India, the trainees on the Neckarsulm website online are growing an extra display rickshaw in cooperation with Nunam. Guests to the GREENTECH FESTIVAL in Berlin can test it out – or even give it a check pressure – from June 22. Underneath the steering of Timo Engler, head of automobile engineering / logistics coaching in Neckarsulm, a twelve-strong group of trainees is enjoying a key position in construction. “The trainees and Nunam are in consistent conversation with every different – we’ve got a devoted line between Neckarsulm and Bangalore. In construction the display rickshaw, our trainees are that specialize in vary, charging time, and design – the result’s a rickshaw with Audi’s DNA,” says Engler. “To us, it’s vital that the trainees are concerned within the challenge from begin to end and are given the liberty to give a contribution and take a look at out their very own concepts. ‘Finding out through doing’ is our recipe for good fortune. On the similar time, we impart elementary wisdom within the construction of electromobility, useful resource performance, and charging applied sciences in a virtually playful, incidental method. It’s a groundbreaking challenge as it combines the megatrends of sustainability, electromobility, internationalization, and social accountability.”

The trainees changed the combustion engine with an electrical one and designed the underfloor to each accommodate the second-life batteries and be splashproof, the use of as many recyclable fabrics as conceivable the entire whilst. Mechatronics technicians, coachbuilders, painters, software mechanics, IT experts and automation technicians have been all concerned within the challenge. “We’re extremely joyful with the intention to be offering our trainees the chance to take part in a world challenge throughout the Basis’s community. It promotes the intercultural change of expertise and generation, from which either side receive advantages a great deal,” says Rüdiger Recknagel.
