The 2018 China Nanjing International Energy-efficient and New Energy Automobile Exhibition went underway Thursday at the Nanjing International Expo Center.
Four exhibition venues are set up for electric cars, electric buses, power batteries and charging facilities respectively. In response to consumers' anxiety about the mileage of new energy vehicles, the exhibition introduced a variety of new energy new vehicles with a battery life of more than 400 kilometers. It is expected that by 2020, the mainstream models will reach 500 kilometers or even more than 600 kilometers to help save the cost substantially.
The key to endurance is the battery technology. Many new energy vehicles have phased out lead-acid batteries with low energy density and long charging time. Instead, lithium batteries with half the weight are used to more than double the storage capacity.
The graphene battery is being development before being manufactured and marketed to enable faster charging.
