Thus, the communications method must be safe and reliable. Although these stacks are inherently dangerous, they must still communicate with the cell monitoring electronics, which are usually located within the battery enclosure. Since it is generally accepted that more than 50 V or 60 V can prove lethal to human beings, and even lower voltages can damage electronic equipment-considering the stability concerns about cells using some types of electrochemical reactions-safety is a key concern. Although we discuss here the use of battery stacks in vehicles, the underlying issues are common to all types of stacks.Д«attery stacks for transportation can typically involve 100 or more cells, providing hundreds of volts. HV stacks are already used in many industries and applications outside of the transportation industry-typically in uninterruptible power supplies (UPS) to store energy from the grid in dc form as emergency dc supplies in 48-V communications equipment as emergency supplies in crane and lift systems and in wind turbines for feathering the blades in an emergency. EVs must be plugged into a power source for charging some newer hybrids are designed as plug-in hybrid electric vehicles (PHEV), which are considered to be essentially EVs with an ICE for range extension.

Such high-voltage (HV) stacks are used in all-electric vehicles (EV)-as well as hybrid electric vehicles (HEV), which rely on an internal-combustion engine (ICE) for charging and (in many cases) shared propulsion. These вЂњgreenвЂќ vehicles rely on batteries of series-connected cells to obtain sufficiently high voltage to operate the motor efficiently.

Isolation in High-Voltage Battery Monitoring for Transportation ApplicationsД¬ars with wheels driven by battery-powered electric motors, continuously or intermittently, have become a hot topic.
