The Third Progress Report on a Wireless Charging Solution for a Sustainable Heating of the Public Electric Transport

“Lesla Latvia” has completed the fourth quarter (01.03.2020-30.05.2020) in the research project “Development of a sustainable heating solution for the salon of the public electric transport”.

During this time, the company has continued research although, have been greatly hindered by the Covid pandemic. Even though the company has been able to continue the research on wireless charging with distance working, the progress was not as fast as initially intended. The researchers made significant progress in the WPT management automation areas and have successfully carried out research on hybrid supercapacitors intended for use within the project for WPT receivers, the results of which were presented in the scientific conference “Engineering for Rural Development” (COMPARATIVE STUDY OF LITHIUM ION HYBRID SUPER CAPACITORS).

However, the research on WPT power increase was severely delayed as it could not possibly be carried out from the lockdown situation.

The area most affected by the corona virus was the social research. The intended interviews with the electric bus users were not possible due to the state of emergency and social distancing. The requirement for cold weather to carry out the research has effectively delayed the intended surveys until next winter. In addition, during the initial state-of-the-art research surprising gaps in the current state of knowledge were revealed, which will require additional data acquisition and a widening of the scope of the passenger surveys. Therefore, we will seek to prolong the project by 6 months until the end of 2021.

About the project:

The goal of the project is to develop an ecologically sustainable heating solution for public electric transport by using heat accumulators.  The new technology will allow the heating of public electrical bus without relying on fossil fuel or extended battery capacity. Heat energy is to be stored in heat accumulator and renewed by wireless charging during stops. The project is run by the Latvia University of Life Sciences and Technologies (LLU) in partnership with eMobility and Lesla Latvia.  

The project is co-financed by European Regional Development Fund. Project identification number is: 1.1.1.1/18/A/168

Trešaisprogresaziņojumsparbezvaduuzlādesrisinājumuilgtspējīgaisabiedriskāelektriskātransportaapsildei

Uzņēmums “Lesla Latvija” ir pabeidzis pētījuma ceturto ceturksni (01.03.2020-31.05.2020) pētniecības projektā “Sabiedriskā elektrotransporta salona ilgtspējīga apsildes risinājuma izstrāde”.

Šajā laikā uzņēmums ir turpinājis pētījumus, lai gan tos ir ievērojami kavējusi Covid-19 pandēmija. Lai gan uzņēmums ir spējis turpināt pētījumu par bezvadu enerģijas pārraidi (WPT), progress nebija tik ātrs, kā sākotnēji bija plānots. Pētnieki ir panākuši ievērojamu progresu WPT vadības automatizācijas jomās un sekmīgi veikuši pētījumu par hibrīdu superkondensatoriem, to izmantošanā projektā WPT uztvērējiem. Pētījuma rezultāti ir prezentēti zinātniskajā konferencē “Engineering for Rural Development”  (COMPARATIVE STUDY OF LITHIUM ION HYBRID SUPER CAPACITOR). Tomēr WPT jaudas pieauguma pētījumi tika stipri aizkavēti, jo tos nebija iespējams veikt karantīnas apstākļos darbā attālināti.

Visvairāk korona vīruss ietekmēja sociālo pētījumu darba paketi. Pētnieciskās intervijas ar elektrisko autobusu lietotājiem nebija iespējamas ārkārtas stāvokļa dēļ, ievērojot sociālo distancēšanos. Prasība pēc aukstiem laika apstākļiem, lai veiktu pētījumus, ir aizkavējusi apsekojumus līdz nākamajai ziemai. Turklāt sākotnējos pētījumos tika atklātas pārsteidzošas nepilnības pašreizējā zināšanu apjomā, kam būs nepieciešama papildu datu iegūšana un pasažieru apsekojumu apjoma paplašināšana. Tāpēc mēs ierosināsim pagarināt projektu par sešiem mēnešiem līdz 2021. gada beigām.

Lesla Technology develops a wireless charging solution for the sustainable heating of public electric transport

On July 1, 2019 “Lesla Latvia” has started participating in the research project “Development of a sustainable heating solution for the saloon of public electric transport”.

The goal of the project is to develop an ecologically sustainable heating solution for public electric transport by using heat accumulators.  The new technology will allow heating of public electrical buses without reliance on fossil fuel or extended battery capacity. Heat energy is to be stored in heat accumulators and renewed by wireless charging during stops.

The project will be run by Latvia University of Life Sciences and Technologies (LLU) who has experience in bus transportation research as well as previous basic research in heat accumulators. Two project partners are eMobility, who have developed an electric minibus, that will be the base for the research; while Lesla has developed a novel wireless charging technology for electric cars. In this project it is planned to combine the expertise of all partners to reach a common goal.

  • Transport in Latvia accounts for 18% of  all CO2 emissions, while in Riga it reaches up to 36% and is the biggest source of all the GHG emissions.  8% of these emissions come from public transportation – buses.  In Riga  currently operates 447 buses, that is 25% of all buses registered.  As buses make only 0.6% of all vehicles registered in Riga while making 8% of all CO2 emissions, it is obvious that public transportation is one area where the implementation of emission-free vehicles can give the most effective results.
  • Currently the number of electric buses in the world is very low. Even though in 2016 more than 40 cities worldwide were operating battery – powered electric buses, there were many drawbacks such as higher upfront procurement costs, imminent falling technology costs, necessary infrastructure investments and limited e-bus model choices. The batteries are one of the most expensive parts of electric buses.  Although the prices for batteries have fallen enormously of late, the costs are still considerable.
  • Within this project, the Latvian university of life sciences and technologies will research technologies necessary to transfer and accumulate energy for HVAC in electric buses in a way that does not require battery power, nor direct fossil fuel consumption.

Wireless electric vehicle charging for commercial users: feasibility studies

The “Cost-effective electric vehicle charging for public spaces by novel core-less wireless charger technology” is part of the Wireless electric vehicle charging for commercial users: feasibility studies competition, funded by the Office for Low Emission Vehicles (OLEV) in partnership with Innovate UK.

As a first phase of an innovation funding programme worth c£40m, 27 feasibility studies will analyse the application and impact of innovative technologies for EV charging.

In particular, 18 feasibility studies will focus on how a well-design, well integrated EV charging infrastructure in public spaces can help facilitate the adoption of EVs among local residents without access to home charging due to lack of off-street parking.

9 feasibility studies will instead focus on the application of Wireless EV charging to commercial users, reducing business disruptions to charge the vehicles and therefore increasing the attractiveness of the EV proposition.

These projects will define feasibility and sustainable models to maximise effectiveness and impact of infrastructure deployment. The wide variety of technologies and business models analysed in these studies will help implement a charging infrastructure that is affordable, dependable, and fair for all road users, and making owning an EV an attractive proposition for all.  

In a subsequent phase of the funding round, the best projects will be competing for funding for implementation of real-world demonstrators.
