1
We're here at Precision Auto Service in Langley, BC, where a customer has brought in a 2016 Fiat 500E for repair.
2
The car was towed all the way from Vernon, BC, over 400 kilometers away from the shop.
3
The customer reported that the car would not go into ready mode.
4
The dealership had told the customer
5
that the entire battery pack would have to be replaced at a cost of around $20 ,000, and that was if a replacement could be found.
6
Precision Auto's diagnosis revealed a fault within the battery pack control module.
7
Replacement BPCMs are not readily available either, but Precision Auto is well connected and was able to source one from a company in Europe.
8
After the replacement module arrived, it was time to perform the repair.
9
The first step is to disconnect the 12 volt battery.
10
Yes, most EVs have a 12 volt battery to run accessories like lights, wipers and infotainment systems.
11
Next, the high voltage service plug is removed.
12
On this model it is located under the rear seat.
13
The service plug is like a giant fuse, this one is 350 amps.
14
Once removed, the high voltage is isolated to the inside of the battery pack, making it safe to work on the vehicle.
15
The battery pack is removed from under the car, so the car is lifted with a hoist.
16
On the Fiat, the battery pack extends from just rear of the front wheels almost to the back of the car.
17
The rearward part is where the fuel tank would be on a gas -powered car.
18
Several metal protective covers are removed.
19
This exposes the main high voltage cables, which are colored orange, and the cooling system hoses.
20
This battery is liquid cooled.
21
Even though the high voltage battery has been isolated, the technician puts on rubber electrical safety gloves before proceeding with the next steps.
22
To ensure there are no pinholes, the gloves are tested before each use.
23
This is done by rolling up the open ends of the gloves, pressurizing the air inside.
24
Then the gloves are held to the cheek to check for air leaks.
25
Once the gloves have passed the test, a pair of work over gloves are worn over them.
26
Now the technician is ready to disconnect the electrical cables from the battery pack, starting with the main line and then the secondary line.
27
He places a catchment vessel on a scissor lift table directly beneath the coolant hoses,
28
clamps the hoses, and then loosens the clamps where the hoses connect to the fittings on the battery pack housing.
29
The coolant drains into the catchment vessel.
30
to prevent further spillage while the battery pack is being removed he places caps on the coolant fittings
31
because the battery pack goes over the top of the rear axle the complete rear axle and suspension is removed.
32
When the battery pack is removed, it is going to drastically change the weight distribution of the vehicle,
33
so the technician secures the front and rear of the vehicle with supports beforehand.
34
The technician places the scissor lift table beneath the battery and raises it until it contacts the bottom of the battery case.
35
Now the main bolts can be removed
36
With all the bolts removed, the table and battery pack are lowered together.
37
This vehicle had a considerable amount of mud caked on its underside, so the battery pack cover must be cleaned before it can be opened.
38
No debris should be allowed to contaminate the interior of the battery case.
39
The technician uses a shop vac and compressed air to remove loose mud and dust.
40
Several dozen bolts hold the top and bottom halves of the battery pack case together.
41
These are removed.
42
The top half of the case can now be lifted off, exposing the components of the battery
43
The technician conducts some tests, verifying voltage readings to ensure there are no other problems.
44
Satisfied with the results, he disconnects the cables from the connectors on the BPC -M and removes the module.
45
He then installs the replacement module.
46
The battery pack is now ready to be reinstalled in the vehicle.
47
When an electric vehicle's high voltage battery malfunctions, it does not always mean that the entire battery pack must be replaced.
48
The most common reason a complete replacement will be recommended is
49
because currently there are very few businesses that possess the resources necessary to perform battery pack diagnosis and repair.
50
It is much easier to simply swap out the entire battery pack
51
that said the price of a replacement battery pack is usually prohibitive
52
and in many cases availability is scarce this will change over
53
time as with any new consumer product prices will come down as demand
54
and production increase this will be true not only for complete battery packs
55
but also for the internal components precision auto service is presently one of very few repair facilities
56
that have invested in the tools, equipment and training necessary to diagnose and repair high voltage batteries and other EV components.
57
This too will change as shops start to see a larger portion of their customer base driving electric vehicles.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
