With the advancement of new energy technologies, electric vehicles have already begun to enter people's field of vision, but do you really understand electric vehicles? The most important technology for electric vehicles is its battery technology. The battery is like its heart. Only a strong heart can have a constant power. For the battery type, the most common ones are five kinds of fuel cells. Lithium-ion batteries, nickel-metal hydride batteries, lead-acid batteries, supercapacitors, then what is the difference in performance between them?
The first is the service life, the worst is the lead-acid battery, but this battery has a long history, high reliability, and the longest life is the lithium-ion battery. As the latest type of electromagnetic, it is characterized by long service life and the most environmentally friendly. No pollution.
Secondly, the memory effect, the memory effect is that the battery itself will remember the user's frequency of use, once the formation of memory can not carry out a relatively large degree of charge and discharge, so this is an annoying shortcoming, this shortcoming is more obvious in Nickel-cadmium batteries, and lithium-ion batteries and nickel-hydrogen batteries are completely lacking in this aspect.
The last point is about battery density, which is the energy density. This will determine the car's endurance, the highest is the lithium-ion battery, followed by the nickel-metal hydride battery, other types of batteries are relatively low.
All in all, the new energy battery is in a stage of development, each of which has relative advantages and disadvantages, but at present, the future battery will be led by lithium-ion batteries.
