At the heart of electrification lies battery technology— TEMSA’s cornerstone for sustainable mobility.
Battery Technologies
Battery technologies, at the heart of electrification, are the cornerstone of TEMSA’s sustainable mobility vision. Developed with our own R\&D capabilities, TEMSA battery systems provide high energy density, flexible configuration options, and advanced safety standards, powering both TEMSA vehicles and global Mobility and Electrification solutions.
TEMSA Battery Packs
TEMSA Battery Packs are high-performance systems operating within a temperature range of -20°C to 60°C, available in capacities of 35, 48, 70, 74, and 102 kWh. These packs feature water and air cooling, utilize NMC and NMX cell types, and ensure secure and efficient data exchange through the CANBus communication protocol. The Battery Management System (BMS) software and hardware used in these batteries are developed and manufactured by TEMSA. All data related to TEMSA batteries is collected and analyzed to contribute to next-generation battery development. For future battery solutions, R\&D continues on LFP, LMFP, Blade Cell LFP, Na-Ion cell types, and LV battery packs, aiming to maintain high safety standards while achieving cost advantages at different energy densities. TEMSA battery solutions are not limited to our own vehicles; they also provide electrification solutions across mobility sectors, including agriculture and marine transportation.

TEMSA Battery Packs are manufactured from cell to pack or module to pack at the TEMSA Battery Production Center, which has an annual production capacity of 0.27 GW. Produced batteries undergo cycle tests in an integrated facility area before being prepared for delivery. TEMSA Battery Packs go through rigorous control processes and come with a standard warranty of 5 years / 500,000 km (whichever comes first) and an optional extended warranty of 8 years.
Agricultural Battery
TEMSA leads the transformation in agriculture with innovative energy solutions. Our agricultural battery solution, featuring 74 kWh capacity, liquid cooling, and Lithium-Ion NMX cell chemistry, is specifically developed for tractor electrification.
This technology saves 2,000 liters of fuel per vehicle annually, preventing approximately 22 tons of diesel consumption over a tractor’s lifetime.
Our agricultural battery solution offers farmers both economic advantages and supports eco-friendly, sustainable energy use in the agricultural sector.
Electrification in Marine Transportation
TEMSA has successfully completed Turkey’s first electric sea taxi conversion with projects prioritizing eco-friendly solutions and sustainability in marine transportation. Leveraging our expertise in electric vehicles and domestic battery solutions, the electrification of sea taxis has achieved an annual fuel saving of 8,000 tons. This transformation directly contributes to the International Maritime Organization’s (IMO) greenhouse gas emission reduction targets of 30% by 2030 and 70–80% by 2040.
TEMSA’s TRESS48 and TRESS102 battery packs have passed rigorous certification tests, making TEMSA the first domestic company to receive certification from Türk Loydu.
The first application of TEMSA battery packs certified by Türk Loydu was successfully implemented in Yuka Yacht’s E-Series 700 Openbow boat.
Electric Refrigerated Truck
As one of the first brands to initiate electric refrigerated truck body production in Turkey, TEMSA is pioneering sustainable logistics transportation. This innovative solution completely eliminates fossil fuel consumption used to operate compressor systems in cold chain transportation.
Thanks to the integration of TEMSA battery packs, hybrid inverters, and solar panels, compressors are controlled with energy efficiency. This project not only contributes to eco-friendly logistics systems but also strengthens TEMSA’s unique product development capability and commitment to sustainable technologies. With this solution, developed for the first time in Turkey, the electrification of refrigerated truck bodies is achieved.
