Cleanova are a set of plug-in hybrid vehicles by the Société de Véhicules Electriques (SVE), a joint venture between Dassault, Heuliez and Hydro-Québec.  Cleanova II is based on Renault Kangoo.  In January 2010, SVE has been taken over by Dow Kokam (USA Dow Chemical and US-Korean Townsend Kokam).  In 2009 Dow Kokam received a $161 Million U.S. Department of Energy Grant for Next-Generation Battery Production for the hybrid and electric vehicle markets.  The Michigan-based facility - Townsend Kokam Advanced Battery -is expected to produce enough batteries to supply 60,000 hybrid or electric vehicles per year. Electric car use by country is a measure of the adoption of electric vehicles around the world.  The popularity of electric vehicles has been expanding rapidly due to their increased acceleration and range, government subsidies and environmental sensitivity.  Electric vehicles (EVs) are divided into battery electric vehicles (BEVs) that run only on batteries and plug-in hybrids that combine battery power with internal combustion engines (PHEVs).  As of the end of 2016: Kokam Co., Ltd. is a South Korea based company founded in 1989 by Ji Joon Hong.  It specializes in the design, production and distribution of rechargeable Lithium polymer batteries and energy management systems.  Kokam manufactures over 100 different types of batteries for various applications such as marine, Electric vehicles/Hybrid electric vehicles, military and industrial. P. R. Mallory and Co Inc was a US producer of dry cell batteries (Mercury; alkaline Duracell), electronic components including electrolytic capacitors, and audible warning devices ("Sonalert"), it also was the parent firm of Mallory Batteries Ltd., an Irish producer of Ever Ready batteries.  British Ever Ready had a sizable stake in it by World War II and had a close relationship with Mallory by the late 1960s.  In the US, "Eveready" batteries were a trademark of Union Carbide, which had no relationship with P. R. Mallory. Energy Products Inc. is a privately owned company based in Madison Heights, Michigan.  They are a provider of batteries, chargers, industrial utility vehicles, scrubbers/sweepers and recycling services.  They sell and maintain industrial batteries and charging systems for forklifts, material handling equipment, AGV’s and utility vehicles used primarily in manufacturing and warehousing.  Energy Products is also a wholesale distributor of automotive, deep cycle and sealed lead acid batteries as well as batteries and chargers for consumer electronic devices.  In 2012 Energy Products started engineering, furnishing and installing backup power systems, service testing and provides removal services for a wide range of customers including banks, hospitals, property managers and the telecommunication industry.  Energy Products offers a comprehensive recycling program for all battery chemistries.  In 2013 they announced they recycled over 2,000,000 pounds of batteries in 2012 for customers located throughout the United States. Nippo Batteries Co. Ltd. (formerly "Indo National Limited") is a company that manufactures batteries in India.  The corporate office is in the South-Indian city of Chennai. The company spans 33 offices through the country.  Nippo batteries reach millions of homes through 35 distributors, over 2800 stockists, 900 vans and 500 autos covering over 5 lakh (500,000) retail outlets.  Nippo is the second largest dry cell battery manufacturer in India, with 28% of the market in 2006.  They even started exporting batteries from year 1976 and the first consignment exported to Yemen. A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system (hybrid vehicle drivetrain).  The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance.  There is a variety of HEV types, and the degree to which each functions as an electric vehicle (EV) also varies.  The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist. In a similar vein to packaging, electronic equipment and vehicles, the concept of extended producer responsibility was applied to Batteries in the UK through the transposition of the EU Battery Directive into UK legislation.  The Directive required member states to have put regulations in place by 26 September 2008.  Although the UK managed to introduce the single market requirements by that date, they failed to implement the collection and recycling requirements.  Following a recent consultation, the government laid the new Regulations before Parliament on 16 April which will come into force on 5 May 2009.  Responsibility for the financing of waste battery collection and treatment will be applied to producers from 1 January 2010 whilst retailers will have to offer free take back of portable batteries to consumers from 1 February 2010.  The new Regulations have included some significant changes from the consultation.  Only those that place more than one tonne per year onto the market will now have to register through Compliance Schemes and be required to finance collection etc.  Those below a tonne will now have to register with one of the environmental Agencies for an annual fee of £30 creating a huge disparity between the two classes of producer as the larger ones are likely to have costs that will run into several thousands of pounds.  The threshold for retail involvement has also changed, removing a 280m2 minimum floor space requirement but upping the total weight of batteries sold from 16 kg to 32 kg.  This means that any retail premises selling more than approximately 24 AA batteries a week will be required to offer in-store take back.  The requirements also apply to industrial and automotive batteries, but given the current value of those and their hazardous nature, there is little change to the current commercial processes that already see them all recovered anyway.  The Directive requires member states to be collecting 25% of portable batteries by the end of 2012.  The UK is believed to be collecting around 4%, so this is not without its challenges.  Whether the system being proposed will achieve that remains to be seen, but an increase of these proportions has taken several years longer in other EU countries such as the Netherlands.
