Why do new energy vehicles favor nickel -metal hydride batteries?portable energy storage battery power supply sales

　　1) Nickel -hydride battery electrolyte is unparalleled aqueous solution

　　Nickel -metal hydride batteries are relatively high than heat capacity and electrolytic solution, and the energy density is relatively low. Even extreme abnormalities such as short circuit and piercer occur, the battery temperature is small and will not burn.

　　2) The quality control of the products of nickel -metalized batteries is relatively low, and the possibility of defects due to the manufacturing process is low.

　　3) As of the end of 2014, the proportion of hybrid vehicles for nickel -metal hydride batteries is as high as 73%, and the global hybrid vehicle with hydrogen -mosaic batteries has exceeded 8 million vehicles. Most of Toyota's hybrid vehicles use hydrogen inlaid batteries. The operation of more than 8 million vehicles has never occurred in serious safety accidents. Toyota's Prius represents the representative of commercial hybrid cars. The car uses a special charging and discharging program, so that the battery filling and discharge life can be sufficient for the vehicle for ten years. Nickel -hydride battery is not only the most mature and most commercially valuable battery of the three major systems currently recognized, but also the first choice for hybrid vehicles. Other hybrid vehicles using nickel -hydride batteries include:

　　Ford Escape; Chevrolet Malibu in Chevrolet; Honda Civic Hybrid in Honda

　　2. Nickel -metalized batteries have good fast charging performance

　　3. Nickel -hydride batteries have good low temperature performance

　　(1) Low temperature discharge

　　The hydrogen battery uses an alkaline electrolyte water solution, which can be discharged at a minimum of -40 ° C. At -20 ° C, 2C ~ 3 discharge lithium-ion batteries can be used by an electrolytic solution. The resistance at low temperature increases rapidly. Normal use requirements at 10 ° C.

　　(2) Low temperature charging

　　Low-temperature fast charging nickel-hydride battery can be charged at a minimum of -40 ° C, and can be quickly charged by 1C above -30 ° C. -2
