SA50B Controller
The rated input voltage of the SA50B controller is 250 ~ 420 V, the rated current is 140 A, and the weight is 5 kg. It can control one motor with a peak value of 100 kw. At the same time, it adopts control software based on the AutoSAR architecture, and also has the UDS diagnostic service and fault snapshot function of ISO14229. Whether it is the dexterous operation of industrial robots, the efficient power transmission of new energy vehicles, or the automatic environmental adjustment of building intelligent systems, it can rely on the adaptive adjustment mechanism to maintain stable operation in complex working conditions and changing environments, reduce energy consumption with excellent energy efficiency management, and extend the life cycle of equipment. The modular design gives it the ability to adapt flexibly, and the intelligent diagnosis function is like a dedicated doctor, always monitoring the health of the system, preventing problems before they happen, and continuously injecting strong power into equipment upgrades and industry intelligent transformation.
As a subsidiary of EMAC, EVMac provides electric drive axles, drive motors, power batteries, and vehicle controllers. As the electrification of automobiles becomes an inevitable trend, EVmac has also entered the field of electric vehicle powertrain systems.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
Advantages of SA50B Power Battery
Integrate the motor and transmission system to reduce energy transmission loss and improve endurance.
Highly integrated design saves chassis space and facilitates vehicle layout and battery installation.
Simplify the mechanical structure, reduce the weight of the vehicle, and indirectly increase the payload.
Low maintenance: No complex mechanical transmission parts, reduce gear and bearing wear, and reduce maintenance costs.
