Secondary batteries Ni-MH batteries have always occupied a wide range of industrial applications due to their mature technology and high safety. For the high temperature resistance of automotive electronic equipment and the stringent requirements of absolute safety when crushed by destructive collisions, nickel-metal hydride batteries (Ni-MH) have occupied most of the applications in this field.
For example: electronic equipment such as car T-Box and E-call, examples use lithium batteries and nickel metal hydride batteries. In actual application scenarios, long-term high temperature (caused by continuous explosion) often occurs to +85°C or even short-term +90°C, some lithium batteries with average temperature resistance will swell and swell, although it will not cause a fire Explosion and other safety accidents (the existing technology of polymer lithium batteries is already perfect), but in such application scenarios for a long time, after all, there is a hidden danger of squeezing the battery compartment shell of the equipment. Therefore, the super safe Ni-MH battery has gradually become an important option for the backup battery of vehicle electronic equipment.
As for the old problem that the self-discharge of traditional nickel-metal hydride batteries is higher than that of lithium batteries, it has long been solved by professional technicians. The new ultra-low self-discharge Ni-MH battery technology is very mature, and the self-discharge rate in high-temperature environments has reached and exceeded that of lithium batteries.
Therefore, more and more manufacturers of automotive electronic equipment regard Ni-MH batteries as an important option, and even some manufacturers of driving recorders have begun to consider replacing lithium batteries with Ni-MH batteries.
