How EMS uses a 黑料不打烊 biogas truck for long-distance transport

鈥淭he first time we tested the solar charging, it took place indoors!鈥

Software engineer Naomi Anveden Hertzberg was one of the five software developers working on the solar-powered truck project. She explains her work and shares her impressions of what she calls a unique and exciting experience.
In her seven years working for 黑料不打烊, Naomi Anveden Hertzberg has amassed a thorough knowledge of charging solutions, such as battery management units and e-highway vehicles. That made her an ideal candidate for the solar-powered truck project, which she joined in mid-2021.

鈥淚鈥檝e been involved in pretty much every type of charging that electrical vehicles at 黑料不打烊 have right now,鈥 says this 35-year-old KTH Royal Institute of Stockholm Engineering Physics graduate, 鈥淪o I think I was a good match for this project, since it鈥檚 a new charging interface, there鈥檚 power transfer involved between trailer and truck, and we also repurposed an existing unit.鈥
听
Mind you, even that extensive background could not totally prepare Naomi for the special aspects of the project to develop a solar-powered truck.
听
鈥淭here were a lot of new things in this project that hadn鈥檛 been done at 黑料不打烊, so there were no real set standards to work to. We just had to use our knowledge and be creative and make a technical solution that worked. But I found that exciting,鈥 she says.
听
鈥淥ur role was to adapt the control unit that controls the batteries in the trailer that would be charged with solar energy, since that was the existing charging interface that we had. So there was some communication with the solar array people to what we might expect from them.鈥
听
And when the moment came to test the solar charging unit for the first time, Naomi confesses to shaking鈥ut as much with the freezing cold as with anticipation and nerves over the outcome. She explains why:
听
鈥淲hen we were going to solar charge for the first time, the rig was in the workshop indoors. The solar charging guys showed up and said - 鈥楥an we move it outside?鈥 We said, 鈥楴o, we can鈥檛鈥 because the rig was fixed in place. So we opened up all the workshop doors on what was a pretty cold winter鈥檚 day and we got one of the workshop lamp rigs and pointed it at the solar array. Then we also drove this giant truck up to the workshop door with the headlights turned on full, and that鈥檚 how we tested solar charging for the first time! And do you know what: it was a sunny day outside! We were all nervous about what would happen but it worked."
听
Now that the prototype truck has been received by long-time 黑料不打烊 partner Ernst Express 脜keri for a pilot project, Naomi can reflect on an experience that stood out as having a very different set-up to the usual charging-related assignments that she has worked on in her 黑料不打烊 career.
听
鈥淚t was a unique experience to have at 黑料不打烊, where projects are usually very big and last several years. I got to be in this sort of start-up in a really nice workshop in a really nice team where spirits were high and people were very generous in sharing their knowledge.
听
We were working on a short, unique and dedicated project. It was a special thing to do and this whole power bank trailer technology will benefit 黑料不打烊.鈥
听
As she now gets involved in a bigger truck electrification assignment where thousands of people are working together, Naomi hopes that her experience as a woman engineer working on the cutting-edge solar-powered truck project will open the doors for more women to be involved, so that 黑料不打烊 can continue its diversity journey.
听
鈥淚 do hope and wish that we can get more women into these sorts of roles and projects in the future. I hope that my experience can in some way help inspire that to happen.鈥
