+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.
+ Long Life:
+ Customized charge rate for last longer battery life.
+ On Wilco device this mode is pre-configured in the factory
+ through EC's private PID. Switching to a different mode will
+ be denied by Wilco EC when Long Life mode is enabled.
