The Fraunhofer institute for Transportation and Infrastructure IVI, expert in the field of lithium-ion batteries, and real-time electric vehicle data specialist ViriCiti have been collaborating to prolong battery life and lower total cost of ownership of electric buses and trucks. Over the past months, they researched how battery life can be extended by altering specific aspects of operations. The outcome is a battery stress report that gives operation-specific advice on how to prolong the battery life. It is now available for ViriCiti’s international customers. . . .

To prevent early degradation, the report focuses on power, temperature, Depth-of-Discharge (DOD) and State of Charge (SOC). It also provides a detailed analysis of the battery usage over the evaluated period of time as well as what factors have a negative impact on the life cycle.

The report describes how adapting the charging and operational regime—e.g. interchanging buses on steep roads—will reduce battery stress and increase health. By maximizing battery life, electric operations become cheaper and electric buses and trucks become competitive with diesel vehicles. . . .
