Learn MoreThis white paper examines design considerations for wired and wireless battery management systems in electric vehicles (EVs). High-voltage EV battery packs require complex communication systems to relay cell voltages, temperature and other diagnostics.
Most EVs rely on the Controller Area Network (CAN) protocol for communication between vehicle components and external systems. The Modbus and Local Interconnect Network (LIN) protocols are used by some auxiliary vehicle components that do not require real-time data communication. Protocols like CHAdeMO and CCS have a crucial role in fast charging.
The charge status of the battery was estimated using the main battery current and the mains voltage with the master board. This application has been tested on an electric vehicle. A low cost modular battery management system has been developed that can control the safe charging and discharging of the vehicle battery.
Lithium ion batteries are widely used in portable electronic devices and electric vehicles. Although battery technology has been significantly improved, it does not fully meet the energy requirements of electric vehicles. Electric vehicle batteries are built by serial and parallel connections of many cells to provide sufficient power.
Multiple communication standards are used in EVs or for vehicle charging, including: Most EVs rely on the Controller Area Network (CAN) protocol for communication between vehicle components and external systems.
However, the CAN (Controller Area Network) communication protocol is preferred due to its high reliability in vehicle systems. This is due to the fact that the probability of an error is lowest in the CAN while reading and sending data .
