This is a big step forward for Hyundai (Global Modular Platform): https://insideevs.com/news/457773/hyundai-introduces-electricglobal-modular-platform-egmp/ Features include : 18 minute recharge (to 80%) using 800 V charging on a 350 kW charger Integrated charging control ( 800 v/ 400 V) and bidirectional VTL (vehicle to load) 3.5 kW @110/220 V Most power dense battery Hyundai Motor Group has ever created Switching between 2 and all wheel drive Improved power inverter for the traction motors Be sure to watch the presentation (use CC unless you speak Korean) a lot more details. Sounds like a winner, looks great Hyundai!
There's a lot of interesting information in this presentation. I would have liked to hear more about weight reduction but the new platform is definitely something I look forward to. Automotive News reports (paywall, sorry) that the e-GMP platform is intended for C-segment and larger, so bigger than the Kona. The first vehicle it will support will be the Ioniq 5, a midsize crossover that will launch next year. It will be followed in 2022 by an equivalent Kia. Performance announced includes 0-100 km/h in under 3.5 sec. and a top speed of 260 km/h, presumably thanks to its higher speed motor. The platform includes 5-link rear suspension, so it should ride like a Mercedes! Eddy, do I remember you from csportcoupe?
Looks like they may be doing the Zoe trick of using motor windings as part of a boost converter to charge 800v from a 400V charger
I am sure the flat floor contribution is achieved by utilizing the new low height cell format (550 mm long) as opposed to the present E63 configuration (125mm x 325mm). Can't seem to locate any info about energy density etc at this time. LG Chem has created it's "spin off" company - LG Energy Solution earlier this week and web reference is not found yet to provide. Give it a bit of time I guess. I am also impressed at the statement in the presentation 100km with a 5 minute charge utilizing the 800V charge rate, which pretty much puts it on par with fossil fuels filling time, providing you can find an 800 V charger I am guessing that the battery pack coolant would not have to be the $ low conductive type as it is now separated in the cooling block structure.
Here's another change - better integration of the motor and gear reducer eliminating the redundant 4th bearing and IMO without doubt, the possibility of the clicking problem. Their image with my annotations ...
I believe most Electrify America charging spots have a 350 kW charger or several, which I believe are 800 volts. Not sure who, if any, also have chargers with this much output. We have a guy from ChargePoint on the Podcast tomorrow, so I'll try to remember to ask him about it.
I checked on Plugshare and EVGo and EVconect have a few (5) in California. A dozen or so in Texas and few in Florida but that about it. Really it is primarily Electrify America (and Canada) and Petro Canda that have a fairly decent coverage.
