zero emission drive

Each Minitram car is individually powered by a high performance AC traction motor coupled to a software controlled, three phase inverter control unit. It is powered by a multi-string traction battery using lithium ion phosphate battery modules. These are capable of operating in extremes of temperature from -50°C to 75°C and delivering very high energy output from a comparatively lightweight battery pack.

The battery modules are also capable of high charge rates through a suitable fast-charge infrastructure to provide extended daily duty cycles. In comparison with a standard lead acid traction battery, the lithium cells have approximately 4 times the life expectancy and cost about the same over a 20 year life cycle and provide a superior stored energy/weight ratio.

Minitram Systems have carefully studied the recent advances in lithium battery technology and only use those batteries which have been proven safe for non-flamibility performance.
