Porsche Menunjukkan ‘Konsep’ Pembaikan Bateri Voltan Tinggi

Porsche menunjukkan rupa masa depan pembaikan bateri EV.

Porsche telah menetapkan sendiri matlamat untuk menjual kebanyakan kenderaan elektrik menjelang 2025 – itu akan menjadi anjakan drastik bukan sahaja untuk pasukan jualan, tetapi rangkaian selepas jualan syarikat. Untuk menyediakan diri mereka untuk perkara yang tidak dapat dielakkan, Porsche memodelkan rupa kitaran hayat lengkap bateri EV dalam syarikat mereka – daripada pembuatan kepada kitar semula. Ini sudah tentu bermakna mencari pembaikan bateri EV juga.

Mereka sudah lama memikirkan tentang kebolehbaikan dari awal -awal lagi. Pek bateri litium-ion Taycan, misalnya, membenarkan modul sel 28 atau 33 (bergantung pada kapasiti) dan komponen individunya diganti. Oleh kerana jumlah kapasiti bateri biasanya ditentukan oleh sel yang paling teruk dalam pek bateri, penguji diagnostik Porsche direka untuk mengetahui modul sel yang berprestasi rendah dan perlu diganti.

Porsche menggunakan semula sel bateri berprestasi rendah ini untuk tugas pegun. Bateri ini dibuka ke tahap modul dan dipasang dalam pembawa tenaga pegun, membolehkan bahan mentah kekal dalam edaran.

Porsche juga berminat untuk memastikan pelanggan sentiasa memantau keadaan bateri EV mereka sendiri. Mulai Mac, Pusat Porsche boleh membaca data secara bebas dan menghantarnya kepada pelanggan mereka. Pada masa hadapan, penyelesaian aplikasi akan membolehkan pelanggan mengetahui status kesihatan bateri kenderaan mereka terus daripada telefon mereka.

Walaupun kenderaan elektrik hampir tidak memerlukan penyelenggaraan, kerja pembaikan amat sukar dan mahal, memerlukan latihan pakar dan alatan pakar.

Begini cara Porsche menangani pembaikan EV.

Repair work on electric vehicles requires expert training and specialist tools that Porsche Centres must obtain before they can offer these services.

The service concept for electric vehicles therefore comprises several stages: the basis for this is the high-voltage support centre, which is specifically configured for HV battery repairs, has suitable specialist tools and has specially trained high-voltage experts as well. The sports car manufacturer is also establishing cross-regional hubs at certain qualified centres, which will handle repairs on high-voltage vehicles in areas where there is no high-voltage base close by. The Porsche Centre that originally accepts the vehicle for repairs will take it to the high-voltage hub, where the work will be carried out along with a final quality inspection, before it is returned to the original Porsche Centre.

If transporting the vehicle to a dedicated repair centre is not possible, a ‘flying doctor’ repair technician will be deployed. These mobile high-voltage experts can repair defective high-voltage batteries on site. Ahead of this, the relevant Porsche Centre receives all the high-voltage tools and replacement parts required for the work. This creates a comprehensive service network for high-voltage battery repair.

Three qualification levels for repair work

Last but not least, work on the Taycan, as the first production vehicle with a system voltage of 800 volts, also requires a clear division of tasks and responsibilities. With this in mind, Porsche has defined three qualification levels: qualified electricians, high-voltage technicians and high-voltage experts. Qualified electricians have a basic qualification that allows them to perform standard repairs to high-voltage vehicles, such as changing the tyres or wiper blades. They must be briefed and supervised by a high-voltage technician when working on a high-voltage vehicle.

High-voltage technicians are trained to work on vehicles that have been disconnected from the voltage supply, and are familiar with classifying and storing lithium batteries. They are also qualified to remove and pack high-voltage batteries classified as ‘Normal’ and ‘Warning’. High-voltage experts have the highest qualification level at a Porsche Centre. They are the only people allowed to perform work inside high-voltage batteries, handle high-voltage batteries with insulation faults and prepare and pack these types of batteries for transportation.
