e-bike charge history

My e-bike battery charging history.

A graphical presentation of the first 6 months charge history. Equal to the winter season, one could say.

Location : south Finland, a coastal area, near Helsinki city.

In the first month, until snowfall and icy conditions, I would take a shortcut through forest trails. This added a number of hills to attack – compared to the remaining months of basically flat asfalt.

Charge history – the 1st 6 months

Some facts to keep in mind, to better understand the conditions.

Some facts

Additionally, the lowest freeze of -15*C was around charge #8.


The snowstorm (26th Feb 2022) was epic. Line of sight limited to 100 meters. Large snowflakes. Just under freezing point, so wet snow. So, I am wet, from outside, and inside of sweat. However, in good mood I was and still warm. It was quite a work out. Drained the battery, barely made it all the way home (on a full charge).

About the author


Martin R.C. Andersson started out as a mechanical engineer, slowly developing a soft spot for project management – in which he has worked 10 years as a project manager.

Although having resigned from a corporate career within project management (2015), the soft spot he keeps alive through a keen interest in room environment treatment. By control of sound and light, looking to tweak for that disturbance-free listening… …which should be a norm.

Values silence, and now and then solitude. Thinks Mindfulness is a ‘state of being’ when work really gets done. When thoughts flow – without disruption – to reach either a creative state or finish what’s at hand.

When the outside world is tuned out, performance is tuned in.
Feels best when Minimalism, Functionalism and Art come together.

An inventor by nature.
