How Efficient Is Your EV? It’s Complicated

Cars That Think

The efficiencies are so different because internal-combustion engines convert a lot of energy to heat rather than to mechanical torque. But the efficiency equation is more complicated than that because, unlike petrol pumps, recharging stations do not transfer energy perfectly. Electric dragsters will undoubtedly improve on that.

The batteries have the same energy capacity and power performance as current rechargeable batteries being considered to power plug-in hybrid cars, and they could also be used to power a range of personal electronic devices. One of her recent inventions is a lithium-ion battery powered by engineered viruses. Earlier post.).

Yamaha Joins Global Move to Battery Swaps for E-bikes

Cars That Think

E-bikes are powered by relatively small batteries that can be wrangled by the average person who can handle a carton of milk. E-bikes’ rapid growth in recent years stems in part from their simple solution to the range issue that big, hulking cars typically don’t offer.

How EVs Are Helping Humanity & Saving Lives?

Get Electric Vehicle

They are not only used for personal commuting, but they are also being used in agriculture, public transportation, last-mile operation and even in firefighting. The main type of battery used is Lithium-ion and when the charge is depleted the batteries can be recharged again. In fuel cell cars we do not have to recharge the battery.

Building a Fleet of Personal EVs in Kenya

Cars That Think

A key person involved in the critical tasks of assembling, servicing, and testing the company’s vehicles and related products is Magdalene Maluta. Recharging a depleted battery takes less than 4 hours, Maluta says. We want to add regenerative braking, which converts braking energy into electricity that goes back into the battery.
