Different types of electric vehicles (EVs) have been recently designed
with the aim of solving pollution problems caused by the emission of
gasoline-powered engines. Environmental problems promote the adoption of
new-generation electric vehicles for urban transportation. As it is well
known, one of the weakest points of electric vehicles is the battery
system. Vehicle autonomy and, therefore, accurate detection of battery
state of charge (SoC) together with battery expected life, i.e., battery
state of health, are among the major drawbacks that prevent the
introduction of electric vehicles in the consumer market. The electric
scooter may provide the most feasible opportunity among EVs. They may be
a replacement product for the primary-use vehicle, especially in Europe
and Asia, provided that drive performance, safety, and cost issues are
similar to actual engine scooters. The battery system choice is a
crucial item, and thanks to an increasing emphasis on vehicle range and
performance, the Li-ion battery could become a viable candidate. This
paper deals with the design of a battery pack based on Li-ion technology
for a prototype electric scooter with high performance and autonomy. The
adopted battery system is composed of a suitable number of cells series
connected, featuring a high voltage level. Therefore, cell equalization
and monitoring need to be provided. Due to manufacturing asymmetries,
charge and discharge cycles lead to cell unbalancing, reducing battery
capacity and, depending on cell type, causing safety troubles or
strongly limiting the storage capacity of the full pack. No solution is
available on the market at a cheap price, because of the required
voltage level and performance, therefore, a dedicated battery management
system was designed, that also includes a battery SoC monitoring. The
proposed solution features a high capability of energy storing in
braking conditions, charge equalization, overvoltage and undervoltage
protection and, obviously, SoC information in order to optimize autonomy
instead of performance or vice-versa.
