Zeta (battery for electric buses)

2024: Product Announcement

In mid-January 2024, the Russian company Autonomous Energy Systems presented Zeta lithium-ion batteries designed for public electric transport. These batteries are said to outperform most foreign-made samples in their class.

In the manufacture of Zeta blocks, modern technologies are used, as well as aluminum and composite materials. This significantly reduces the weight of the batteries. Installing new batteries on electrobuses Moscow makes it possible to reduce their weight by 300-400 kg. This can increase passenger capacity or add additional battery modules. In the second case, the range on a single charge can grow by 40-50% with a comparable weight.

"Zeta"

When creating Zeta batteries, great attention is paid to fire safety - at the level of the control system and the materials used. Efficient liquid cooling is involved: the universal heat exchanger is specially designed for use in the most severe climatic conditions. The Block is fully developed and manufactured in Russia: at the same time, the Autonomous Energy Systems company uses its own proprietary thermostating system, control and protection means.

The battery pack with dimensions of 2100 × 960 × 260 mm and weighing 398 kg contains 73.3 kVt·ch of energy. The voltage is 628 V, the energy storage density is 185 Vt·ch/kg. Support for fast charging is provided. One such unit may be sufficient to operate the vehicle on electric traction with a small range of power - for example, a trolleybus. At the same time, a bundle of 2-3 modules will ensure optimal operation of electric buses with fast charging, in particular, machines that meet the requirements of the Moscow fleet.^[1]
