Team-BHP - ZipTron: Tata Motors' new EV technology brand

Ziptron is the nomenclature of the EV tech. from TATA Motors,

- First vehicle to be launched will be in early 2020.

- Ziptton tech has been co-developed at tech centres in UK and India for the past 4 years.

- Vehicles with Ziptron will have driving range of "at least 250 KMs".

- Liquid cooled batteries with 8 year warranty

- Permanent magnet motors mated to single speed transmission for seamless power transfer

- Remote connectivity through dedicated app.

More on the Ziptron Tech.

- System comprises liquid-cooled lithium-ion battery pack and a 300V motor

-The high voltage 300V plus electric motor also promises to be leagues ahead of the current system in performance and output

-Tata Motors has announced 4 all-electric models to be in the pipeline.

- Altroz EV could be the first model to feature Ziptron tech.

Tata Motors unveiled its EV technology platform called Ziptron today. It will power a range of Tata Motors electric cars, starting with a new launch in Q4, 2020.

Main characteristics of Ziptron:
Zippy performance,
Long range,
8 years of warranty on motor and battery,
Permanant magnet electric motors mated single speed transmission,
Fast charging capability,
IP67 rating water and dust proof, etc...

Battery pack includes liquid cooling and advanced lithium ion cells. Battery system can be modular and supports flat floor EVs as well:

Ziptron has been under development for 4 years at tech centers in India and UK.

Interesting reveal. Great that all the cars built on this EV platform are going have a minimum range of 250km.

First car in Q4 2020, hope Tata comes with all guns blazing this time.

Hope Tata to do in auto industry what Jio did in telecom industry.

Wish Tata all the best.

Promising a 8yrs warranty on battery is a tall task. They could have got away with something like 5 yrs. The Battery management system is the most complicated part of an EV. The liquid cooling can probably reduce the thermal imbalance between cells. It is also good to hear that they are taking into consideration the Indian weather. The only thing left is to make the system as reliable as it can be. That would make or break the company.

Well, 8 years warranty is becoming standard on batteries across the world for EVs (USA and Europe). All the automakers are guaranteeing 8 years/160,000 kms warranty with minimum 70% state of health. Even in India, Hyundai is giving the 8 years/160,000 kms warranty on Kona Electric battery.

On the one hand, you have all of this happening. And on the other hand, you have lumbering diesel vehicles such as Tata's flagship - the Hexa. When will the twain meet, even if only in the hybrid format? This platform - the Ziptron - seems suited for powering lightweight hatchbacks and sedans. (And I personally feel that electric cars ought to be made in a 2 seater format, to enable far greater ranges.) But anyway, one somehow feels like an electric or a hybrid Hexa is a distant mirage at this point...

300V Motor? . Interesting, This means that your battery pack would also be rated at 300V DC. Considering that most of the EV motors that are in use today are less than 100V motors. Tesla model S uses a 96V motor i guess. Its not clear what type of motors Tata plans to use.

Altroz?. They are going for the correct band. Instead of going the compact SUV market that Hyundai (25L Kona) seems to be targeting.

I wonder how I came to be totally misunderstood here. I have in fact asked a pretty pertinent question here - will this new tech platform even find its way up the product portfolio or not? I'd love to have something like this on a Hexa. This seems suited to Tata's smaller cars, at the outset.

And I'm a Tata/Mahindra lover by the way :)

High voltage low current is much better than low voltage high current resource for same power levels. Not only it cuts the losses but also allows the Industrial grade technology to be used cheaply in harness the potential which will use otherwise a costly technology.

this is a fantastic news and the ranges seem to make it pretty practical. Charging infra has to catch up at some point and there has to be a start somewhere. Tata is indeed doing its bit and I'm super happy to see this. Im sure over time more powerful batteries can be designed /produced to drive bigger vehicles. The etrons and ipaces have clearly established its quite possible to have 300+bhp for heavy SUVs through electric motors.

+1. I'm sure this is the agency that made the latest Harrier Black edition ad. The worst TML car TVC ever! Reminded me of CG in Captain Vyom that one!

By the way - does it seem like an FWD implementation? Generally EVs prefer to have lower rated (and cheaper to make + longer lasting) motors in a sort of AWD implementation. This also gives a bit of "redundancy". In the schematics that Zip-Tron presentations have, there doesn't seem to be any active drive component on the rear axle & its just rolling wheels?
That would mean much stronger motors would be needed as just 2 will do all the weight pulling. Perhaps thats why the 300V application?

Just out of curiosity, what happens if one fails in such cases? (Not sure if ZipTron is 2 motor, but just curious.) Does it mean the vehicle simply stops and goes into limp mode? Or it will have a considerable torque steer with only 1 side peddling? (Remember - Ross scaring Monica telling Ben is running in circles :uncontrol)
