Electric Toyota MR-S Conversion

[ilogikmr2]

Great car, so how much would it cost to put something like this together and how many miles can you get to a charge?

[sajabz2007]

that .. that was awesome .. ordering a load of laptop batteries and sticking inside a mk5 golf!!!

( gna get googling :P )

How to make a good car amazing :)

[hearttobefelt]

are you sure its 72 TS cells ? he must have half in parallel to give 144 volts for the netgain motor

he could have used 45 x 200 AH cells for same 144 volts and similar weight and saved half the cost of BMS

[m1aws]

@hearttobefelt No car manuf'r ever uses a BMS. So DON'T!

BMS's burn cars down without exception! Go google with, Lincvolt, car ferry, evtv, etc. All had a BMS on a night charge.

The best bet with lithium is not allow over charging, current, (heat) or overvoltage, (blow out). Simply adjust the charger. Whenever your batteries are low-ish, check the voltages. Make them equalised at the bottom so the stronger ones don't reverse voltage the weaker ones. This way they are good for 3,000+ cycles.

I am from Glenfield, North Shore City. I am a very keen would be EV owner. Can I have a view of the car?

WOW!! PORSHE 911 TURBO GET OUT, I HAVE A NEW DREAM CAR!

lol powerful electric mr2 spyder? that's cool!

i loved the last footage just before 1:08

beautiful!

Tesla eat your heart out.

[Rikiru]

It basically is a Tesla :P

Both are based on the Toyota MR-S (MR2 Spyder) chassis. There is 0 new technology in the Tesla...not even the Carbon Fiber body is that impressive by today's standards.

[ev1nut]

The Tesla and MR2 are completely unrelated. Tesla created a unique chassis using Lotus's extruded aluminum technology.

You are partially correct saying there is no new tech in the Tesla... Lithium cells were used in the Nissan Altra and Hypermini in the late 90's and the powertrain descended from the GM/Hughes Dolphin system. The Tesla is to these cars what the Ford Model A was to the Model T, much better in every respect.

P.S. Tesla is an AC motor and cylindrical lithium ION cells.

[m1aws]

@Rikiru There is not one correct sentence here. The Tesla has Lotus Elise chassis and body. Its got a 3 phase AC motor and a 53Kwh pack with 375 volts static charge using cylindrical cells..

[PBScenarioScene]

@m1aws The Lotus Elise chassis IS an MR-2 Spyder chassis! The freaking Lotus uses a 2ZZ-GE engine and 6-speed transmission from the Toyota MR-S / Corolla XRS. As far as the 3 phase AC motor and lithion batteries, they've also been around since the 90's. Nothing new in a Tesla except some carbon bodywork (not a new concept either).

[m1aws]

@PBScenarioScene Why and when would Toyota utterly change its design to implement a lotus chassis? That's an extruded aluminium, glued design. You are thinking of the Vauxhall VX90, The Tesla roadster and of course the Elise family.

Don't believe me? Then please look it up. Better still, crawl under both cars.

The Lotus has used quite a few different powerplant combinations. The first version used a Rover K series because it was the most compact and light.

Anyway, this is a digression.

Hey guys, it's not my car, but the stats are: > Donor: 2000 Toyota MR2 Spyder (MRS) > Style: 2 seater mid-engined convertible > Battery Pack: 72 x 90 Ah Lithium (LiFePO4) > Nominal Capacity: 230.4 V x 90 Ah = 20736 Wh > BMS: Blade EV > Motor: Netgain Warp 9 (series DC) > Motor Controller: Zilla Z1K > Transmission: Factory 5 speed > Fuel gauge: Metric Mind EVision > Charger: Manzanita Micro PFC-30

[ilogikmr2]

looks like its got some power, whats it using to run?

[Adamal1]

So an electric motor mated to a manual gearbox? Awesome!

[sxyrx7]

what motor and batterys are you using ac/dc wet/dry cell

[deafrattle]

wicked :-)
