Hyundai, Kia Motors to develop new solar charging tech for vehicles

(Reuters) - Hyundai Motor Co (005380.KS) and its affiliate Kia Motors Corp (000270.KS) are planning to launch a solar charging technology for some Hyundai vehicles to meet global emission regulation targets, the South Korean automakers said on Wednesday.
Solar panels will be mounted on the roof or hood of the vehicles, the companies said.
The companies are launching three solar charging systems for several types of vehicles, including hybrid and battery electric.
Several countries have in recent years set ambitious goals to cut carbon dioxide and nitrogen oxide emissions, bringing carmakers and truckmakers under greater scrutiny.
Hyundai is set to launch the first generation of the technology for its vehicles after 2019.
The one we'll see first will exist on hybrids. This tech involves adding silicon solar panels to a regular ol' car roof. Hyundai and Kia estimate that this solar roof can add between 30 and 60 percent of a battery's capacity over the course of a day -- weather depending, obviously. Considering hybrids have the smallest batteries of all, this is a good place to start.
But the second-generation system will bring solar-based charging to a class of vehicle not normally pegged for this kind of tech -- cars with traditional internal combustion engines. Here, a semi-transparent solar panel can be added to a panoramic sunroof, boosting a vehicle's battery while still letting light into the cabin. It's unclear if these cars will pack slightly larger batteries, or if the panel will merely take some load off the alternator, but Hyundai and Kia say the tech will help the company comply with future emissions standards.
The third-generation system is the furthest out. This one benefits battery-electric vehicles, and it adds solar panels to both the vehicle's roof, as well as its hood. That would give EVs even more solar-panel real estate to convert to energy for batteries, extending range and reducing reliance on grid power, which could come from dirtier sources.
Hyundai and Kia estimate that their first-generation solar roof tech will reach vehicles in 2019, but timelines for the second and third generation have not yet been announced. If this tech can produce tangible benefits, I wouldn't expect this tech to stay limited to just Hyundai and Kia for long.
