Battery charging delimiter
Posted: Friday 08 December 2023 23:34
I just wrote a dzvents script to delimit our electric car charging to somewhere between 80 an 90%.
It works for the car, it works for de electric bike battery, it works for the mobile phone, it works for every battery.
By delimiting the maximum charging of a battery below 90% battery life will be extended.
We're using the property of batteries that when these reach to 100% the charging speed - read delivered power - will fall off.
Here's the code:
BTW Most electric cars have an option in the menu to delimit charging to a fixed percentage.
Bicycle battery chargers and the grand majority of other battery chargers don't have that option.
