Battery

• It is the only power source of the drive system in pure electric vehicles, mainly including nickel cadmium, nickel hydrogen and lithium ion batteries. At present, the lithium ion battery is in a stage of rapid development, and it is used in many new energy vehicle, such as the Nissan Leaf, TOYOTA Prius plug-in, Tesla Model S, general Volt Focus, Ford EV and BMW I3 and so on. In addition, lithium resources are more abundant, and the price is not expensive, it is said that lithium-ion batteries are currently the most popular in market power battery.

Fuel cell characteristics

• It is a device in which the chemical energy of fuel and oxidant is changed directly into electric energy through the reaction of electrodes. The fuel cell does not need charging, and has the advantages of high specific energy, long service life, less maintenance work and continuous power supply. In addition, fuel cell vehicles can achieve over the same mileage as fuel vehicles. According to the electrolyte, fuel cells can be divided into five types: alkaline fuel cells, phosphoric acid fuel cells, proton exchange membrane fuel cells, dissolved carbonate fuel cells and solid oxide fuel cells. At present, proton exchange membrane fuel cell (PEMFC) is widely used in fuel cell vehicles. It is the most competitive battery type in the future of new energy vehicles and power batteries.
