What: /sys/class/power_supply/wilco-charger/charge_type

Date: April 2019

KernelVersion: 5.2
|
|
Description:
|
|
What charging algorithm to use:
|
|
|
|
Standard: Fully charges battery at a standard rate.
|
|
Adaptive: Battery settings adaptively optimized based on
|
|
typical battery usage pattern.
|
|
Fast: Battery charges over a shorter period.
|
|
Trickle: Extends battery lifespan, intended for users who
|
|
primarily use their Chromebook while connected to AC.
|
|
Custom: A low and high threshold percentage is specified.
|
|
Charging begins when level drops below
|
|
charge_control_start_threshold, and ceases when
|
|
level is above charge_control_end_threshold.
