The battery pack produced by Autonomous Energy Systems (SAE) began to be used at the urban electric transport plant in Chelyabinsk. They are installed on trolleybuses with autonomous running “SINARA-6254”.
The batteries of our production have become the basis of energy storage systems created by the company, part of the Holding Company STM – LLC “STM-ENERGORESHENIYA”. The main advantage of the new solution is the record gravimetric energy density, which is significantly higher than that of other existing Russian batteries and is not inferior to its foreign counterparts. It is about 150 wh/kg.
The battery pack of the new trolleybuses is as compact as possible — the height of one battery is only 141 mm and the weight is 210 kg. The system is equipped with a patented built-in heating and liquid cooling function, due to which it can be operated in all weather conditions.
The powerful and compact battery system ensures long-term autonomous driving even in winter conditions.
The first batch of trolleybuses with new batteries will be 98 units. Of these, 20 vehicles are almost ready, and will enter the routes in the near future. Over time, such trolleybuses will completely replace the fleet of outdated rolling stock in Chelyabinsk – there will be 168 of them in total in the capital of the Southern Urals.
