Our belief: A person may do an immense deal of good,
if they do not care who gets the credit for it.

What Are We Building?

Portable power from Used EV batteries

Portable power from Used EV batteries, A low-cost, portable, Lithium-Ion battery pack that can be endlessly replenished! At Totus Power, my team and I are building such a device (christened Jupiter6) from used electric vehicle (EV) batteries. These batteries still have sufficient capacity after their automotive life but are now prematurely recycled. Our short-term objective is to enable solar power access for families and schools in low-income communities in developing countries. Each unit of Jupiter6 charges via solar panels, or an AC adapter and can power many phones, tablets, and lamps (Capacity: 300 Wh), replacing toxic lead-acid batteries or kerosene lamps. Jupiter6 works like Lego, with the used EV battery and control electronics in separate sections that snap together. Thereby exhausted batteries can be easily replaced and returned for recycling.

Along with our partners, we are piloting a fully operational model that aims to comply with all current and future recycling regulations. Our long-term objective is to make this knowledge freely available and facilitate the reuse of these batteries in social impact projects worldwide, maximizing the value of used electric car batteries from all manufacturers. Product stage: Pre-production prototype under development for field trials;

Update: After working on this since 2013,  I sadly announce that we have retired the idea behind Totus Power.  We concluded that it just isn’t commercially viable to reuse old EV batteries in developing countries.  The full analysis is available on – Thanks for your interest. Regards, Siva Rajendran (Former CEO and Founder of Totus Power).

The Problem – Energy Storage Ignored!

The problem we seek to address is the lack of access to clean solar power in developing countries because of expensive batteries. On the other side, useful batteries from old electric vehicles (EV) are wasted by premature recycling. Why can’t these batteries be used to solve the problem of energy access? That is the premise of our work.

In developing countries, over 700 million people live in low-income communities without electricity infrastructure, but they can have power now via solar panels. However, the penetration of solar power in this population is minimal. Batteries account for 60% – 70% of the cost of solar power and are still prohibitively expensive. By 2020, there will be enough old EV batteries to power 1 Million low-income families a year. By reusing electric car batteries in low-income communities, we can solve a real need while providing tangible benefits to the automaker, in a regulatory compliant program.

The BBC recently featured our idea on their science show, BBC Horizons. You can learn more about the problem via that feature listed below (
