Following the first generation mining car, the second generation mining car is born. The first and second generations were upgraded in very important parts. “Secondary battery” was added immediately. In the first generation mining car, mining was possible while driving, that is, while the engine was running, but it had the disadvantage of turning off the mining computer as the power supply was cut off when the engine was turned off. To complement this, the second-generation mining car has a secondary battery, a lithium iron phosphate battery, and the stored secondary battery supplies power to the mining computer even when the engine is turned off, so continuous mining is possible even when driving is temporarily suspended.
The second-generation mining car system was applied to the Mercedes-Benz E-Class, a more advanced version of the Toyota Camry, the first generation mining car. The design of the same pattern was changed to a new color and wrapped to show that it has evolved into the second generation.
The biggest feature of the 2nd generation mining car is the addition of a “secondary battery”. These days, the ratio of female drivers is almost equal to that of males. The characteristic of female drivers is that they stop by many places rather than driving for long periods of time, so even if the engine is turned off, they must be able to continue mining for at least an hour, which was the biggest characteristic of this second generation. And in the end, VMS did it.
