Exoès and Saft partner to improve Li-ion battery thermal management

Green Car Congress

The temperature of a Li-ion battery has a major influence on its performance and its lifespan. The company, founded in 2009, has developed the Organic Rankine Cycle (ORC)-based EVE (Energy Via Exhaust), an exhaust waste heat recovery technology which reduces heavy-duty engine fuel consumption and emissions.

Environment Canada study finds vehicle exhaust a significant source of isocyanic acid; suggests consideration of new emission standard

Green Car Congress

Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. Automobile exhaust is also a known source of inorganic acids such as nitric (HNO 3 ) and nitrous (HONO) acids.
