Multi-purpose sulphur-sodium cell and mockup battery of twelve cells for electric car

The report provides results of electrical tests of multipurpose cells and electric car mockup battery of twelve cells. It is shown that, sulphur-sodium accumulators, being produced at STC “ISTOK”, have adequate reliability in testing under electric car batteries conditions. They withstand discharge current of up to 1.0 A/cm² density and demonstrate consistent characteristics at operating current densities of 0.1-0.3 A/cm². Results are represented on safety tests, including those with deliberately destroyed electrolyte. The mockup battery can operate according to the electrical car driving runs, the mockup characteristics here do not deteriorate when transmitting up to 50 A current
