Yongming capacitors help the automotive electronic power domain to operate stably!

With the increase of ECUs (Electronic Control Units), automotive logic control is becoming more and more complex. The initial logic of domain controllers does not exist to reduce the number of vehicle ECUs, but to integrate data and enhance computing capabilities. The so-called “Domain” is a collection of electronic and electrical architecture that controls a certain large functional module of the car. Each domain is uniformly controlled by a domain controller. The most typical division method is to divide the electronic and electrical architecture of the entire vehicle into There are five domains: power domain, chassis domain, body domain, cockpit domain and autonomous driving domain. 

The power domain is the safety domain. It is an intelligent powertrain management unit. It is mainly used for the optimization and control of the powertrain. In electric vehicles, it mainly refers to the integration of electric drive and electronic control systems. It also has electrical Intelligent fault diagnosis, intelligent power saving, bus communication and other functions. Taking new energy vehicles as an example, the power domain includes electronic control systems, battery management systems (BMS), electronic water pumps, on-board chargers (OBC), etc.
