smart ED3 17.6kWh battery repair (feat.P18051C / bricked BMS)

The battery of the smart ED3 very reliable and robust, however, it still can fail some times. In the following I would like to list everything that is available and how to repair or replace it:

• Desiccant cartridge
• Bricked from an accident
• Deep discharge (P18051C)
• Current sensor
• Battery cells & module replacement
• HV contactors

You will also find useful additional information on how to prevent these defects. Should something break, you can find suitable used parts in the Shop, there you will also find the offer to reset the P18051C error.

I'm very prowd of this article, we've been working on it since the start of this year:
