Model Y again

This Standard Range model uses LFP battery

In this video, I will conduct a supercharging and range test

I do a lot of reseaches for each video

Please subscribe

and activate the notification bell

For Tesla using LFP battery, the charging page will display 50% and 100%

Instead of "Daily" and "Trip" in previous models

Chinese HK version of the Model Y Owner's Manual is not available yet

I will show you guys the manual of Model 3 instead

They are more or less the same

Manual recommends charging limit to be set at 100% (LFP battery)

and charge to 100% weekly

Elon Musk said in August that LFP battery prefers 100%

while NCA pack is recommended at 90%

I shared in my Use Tips video last year, 80-90% is recommended for daily use

I think NCA battery pack can still be charged to 100%

but only if long trip is to be done afterwards

Prolonged parking after charging to 100% is not recommended

I reckon these % are only recommendations

which can be followed if situation allows

The vehicle is meant to serve the owner

You have 8 years / over 100k km warranty for the battery and drive unit

There is no need to worry too much

But at 100%, regenerative braking may reduce

Brake has to be applied more

But for this Model Y SR, regenerative braking does not have obvious reduction

The level is similar to usual

If you have different observation, feel free to drop a comment~

Energy density of LFP battery is usually lower than NCA

Therefore, for the same battery capacity

Weight would increase for LFP

Those previous Made in USA Model 3, including SR+/LR/P, use NCA pack

SR+ is less heavier than LR/P for about 200kg

Now, this LFP Model Y SR is without a front motor

and the battery capacity is smaller

but the weight difference is only a couple of kilos

Manual also recommends turnig off sentry mode if it is not needed

E.g. at home

Allowing the vehicle to enter "Sleep Mode"

2021 Made in Shanghai Model 3 SR+ is already using LFP pack

I have been long waiting to test its charging power

Especially Supercharging

My experience is that the last few % would be very slow

I rarely charge to 100%

Usually at around 90%

If someone is waiting at the charing station

I won't charge to high %

I am interested to see how this LFP Model Y performs during the last 10%

13% remaining

Charge with V3 Supercharger

Model Y and Model 3 in HK both adopt CCS

V3 only provides one connector

But there are 2 for V2 Supercharger, remember to use the larger connector

and slightly secure the other connector to avoid it getting loose from the mount

It often falls off

and may hit your trunk

Model 3 SR+ with NCA pack showed 170kW max at V3 Supercharger

and maintained this rate until 20 some %

This Model Y SR with LFP pack peaked at around 164-166kW

Charging started at 12%, the rate quickly went up to 164kW

But it only kept there for only 2%

For NCA models, charging at 100% SOC

would take a long period of time to complete

It may take more than 20-25 mins

This Model Y SR took long time too at 100%

I intended to let it complete itself

But it did not finish for over 20 mins

I had to give up

If someone is queuing for a spot, charing to 100% is not very recommended

because of low charging efficiency at high %

As I said

It is better to do it with your own charger

The overall behaviour is similar to a foreign YouTuber

He tested with a LFP Model 3 SR+

54kWh of electricity was consumed during this supercharging

For peak hour, HK$3.1/kWh, cost would be HK$167.4

For non-peak hour, half price, cost would be HK$83.7

After range test, I will do the per km cost calculation

440km range displayed at 100%

Not the official figure 455km(WLTP)

Similar to my Model 3

Official range is 409km(WLTP)

But only 38Xkm was shown at 100% when I first collected the car

The displayed range is based on US EPA

The manual says displayed range is adapted based on battery condition and fixed EPA test data

Not your personal driving patterns and other external factors

For different range standards, check out my previous Use Tips video

To put in simple, NEDC provides the highest number

then WLTP

and EPA the last

EPA therefore represents better the actual range

But just like those fuel efficiency figures of ICE vehicle

Factory figures are often ideal only which are difficult to achieve

With such a long introduction

It's time for a range test

I thought of just cruising on highway only

But I prefer doing it in "daily life" style

which includes highway

and city driving

Keep AC on

Split into 2 days

Normally a daily round trip would not be several hundreds km in HK

I guess my test would be closer to actual experience

I am going to briefly report the battery consumption at each checkpoint

For result, skip to the later part

Supercharging completed

First destination is HZMB Carpark No.1, from Sham Shui Po

Trip is about 27km

Consumed 6%

94% left

Stopped over here for over an hour

with AC on

91% battery remaining before heading to the next place

Next is Gold Coast in Tuen Mun

Via TM-CLK Link Tunnel and then Castle Peak Road

16km

88% left

Parked for about an hour

To have a short meal

With sentry mode on

1% battery consumed

Next is Nam Sang Wai in Yuen Long

22km

5% consumed

65km accumulated

Luk Keng the next

via San Tin Highway and Lung Shan Tunnel

approx. 28km

76% battery left

Last is Sai Kung before going home

This trip is a bit longer

38km

7% used

Back at home

162km accumulated today

60% left i.e. 40% consumed

Usually keep sentry mode off at home

Let the vehicle enter "Sleep Mode"

Let's see what would be the battery level tommorow

Day 2

After around 16 hours

with sentry mode off

Battery level is still 60%

Let's go to HK Island for today's first destination

Shek O

via Harbour Crossing Tunnel and Island Eastern Corridor

33km

Used 8%

Next is Cyberport

28km

45% remaining

Back to Kowloon

via Pokfulam and Harbour Crossing Tunnel to Tsim Sha Tsui East

16km and 3% consumed

Next is Sunny Bay

24km

263km accumulated already

More than that I achieved with my 2019 Model 3 SR+ under 90% to 10%

For 80%, I achieved 260km (Model Y SR 65% 263km in this test)

Final stop at Nam Sang Wai again

Test completed

25% remaining

A circle around Hong Kong in 2 days

From 100% to 25%

i.e. 75% for 306km

Official range WLTP 455km

For 75% is 341km

Actual range in this test is 306km, which accounts for around 90% of the official range

Exceed my expectation

If I drive until 0%

It should go all the way to 408km

Regarding the average cost per km

During peak hours of Supercharger

HK$167.4 charging from 12% to 100%

88%

For 75%, the cost is around HK$142.7 plus parking fee = HK$170.7

divided by actual range 306km

Cost per km is $0.56

For non-peak hours, HK$0.32 per km only

For private home charger

Non-domestic around HK$1.16 per kWh(Monthly 301 to 400kWh)

Average cost per km is only HK$0.17 for this test

I wanted to drive till 10% remaining

but it should be enough

to serve as a reference

Of course it varies with different driving habits

Some would be higher and lower

Hopefully this test can help you understand more

See you in the next video~
