I'm glad that I retired from underground mining after 43 years, as I am not a fan of any battery operated scoop tram, diesel powered or nothing for this oldtimer!
The MEC500 mobile charging station is a glorified fast charge station. It still needs a 480V or 600V 500kVA grid connection through an isolation transformer, so the idea that its "portable" is a bit of a stretch. It has 500kW of fast charge POWER not 500kWh of battery storage, please learn the difference it is VERY different.
Hi K, thanks for watching. You're right about capacity and power being different. However, I wanted to address a couple of things you said and provide some clarity. The MEC500 contains a 500 kWH battery. It is not a glorified fixed fast charge station as you said. 500 kWh is the MEC unit's battery capacity, not its charging power. As such, it is a portable fast charging station. Because it contains a battery, you do have to connect it to the grid-but only to charge it up. Once it's charged, it can be disconnected and dropped where needed. Again: It does not require a tethered connection to the grid when charging a machine. As to your comment about power, again, the 500 kWh rating pertains to capacity not charging power. In terms of power, the unit is capable of adjustable output voltage between 300 and 1,000 volts and up to 700 Amps. This allows it to fast charge or trickle charge based on what the machine needs. Hope this clears things up for you. Thanks again for watching. - Wayne
@@Forconstructionpros1 It doesnt have a battery in there at all, go check the spec sheets. You can even rationally check this claimed "500 kWh" vs their mass, the energy density would need to be an order of magnitude better than the best Tesla has ever put out there. The marketing team is lying because they dont know the difference between kW and kWh.
@@j4k3br4k3 I agree with you. There is no internal battery. The charger needs to be connected to the grid. The amount of power to charge this in 20 minutes is insane. Enough power for a few blocks of single family homes in the middle of summer.
@@j4k3br4k3 You are definitely correct, it's a charger, not a power supply. No different to you charger you get with your battery tools. It has some fancy charge control systems in it but will not charge a machine just sitting there by itself. The company I work for is working with Caterpillar and we have developed a containerised system that contains the MEC500, a transformer and a Cat generator that can be dropped in place and charge a machine without any grid connection.
@@Forconstructionpros1 it's definitely just a charger, not a power supply. No different to you charger you get with your battery tools.

I've worked with MEC500 and to make it operational you need a transformer and a 500kw power source, be that mains input or a generator. It certainly cannot charge standalone.
