Dubai rental company buys EJT battery storage units

Chinese battery energy storage specialist EJT New Energy is supplying its units to rental companies in the Middle East and Singapore, as well as Europe.

Jason Zhang, a co-founder of the company – which is based in Xi’an, central China - told IRN that 10 of its energy storage units have now been delivered to rental companies in Singapore and Dubai, UAE.

The Dubai customer is Al Shola Transport, a big transport and equipment rental business with offices in Dubai and Fujairah in the UAE and in Oman.

Zhang, who has a background in power electronics and battery technology, said the business was founded in 2021/22 and is now developing products for both mobile and stationary battery power applications.

A major target market is equipment rental firms using BESS units as part of a hybrid power solution, alongside traditional diesel generators.

The company is using lithium-ion batteries from Chinese supplier CATL and the controllers are from ComAp. It is making 100kW, 250kw, 430kW and 1000kW (containerised) units, all with IP55 protection and capable of working in temperatures from -30C to 60C.

For the Dubai units, ComAp worked with EJT and Al Shola to supply a control system using its InteliNeo 530 BESS system to allow for easy integration with the rental company’s existing diesel genset fleet.

The controls integrate the battery management system (BMS) with the power conversion system (PCS), and control and monitor the unit, as well as enabling integration with diesel gensets.

Zhang added that the company is also working in Europe, with partners including Netherlands company PeerGen.

The MobileESS 215 specification includes rated AC power of 215kW, peak power of 300kW and matrix power up to 430kW. It uses a 215 kWh CATL LFP (lithium iron phosphate) battery designed for mobile use.
