About EVT Technology

ElectrifyEVolve the Power Ahead
EVT Technology was founded in 1999. After years of R&D efforts in e-vehicle powertrain, EVT successfully developed and first put the "Direct Driven Hub Motor" and PWM intelligent controller into the 2-wheeler and 3-wheelers electric vehicles (EV).

Facing the new era of electric vehicle, EVT further has excelled its e-drive solutions for low-speed EV applications by providing AC motor controllers and customer integration service. The motor controllers come with robust design and innovative features that are suitable for industrial and commercial vehicles applications both on and off roads, with tremendous outcomes on industrial vehicles to the market such as e-forklift and e-truck. With solid vehicle electrification experience, EVT also provides powertrain system integration service to help customers in speeding-up product’s time to market.

EVT continuously will contribute considerable resource in the development of EV power electronics to sustain green e-mobility.

Motor Controller - CR Series for Low Voltage EV Application

CR Series is designed for low voltage,48V~96V, motor applications in low speed electric vehicles (EV) and industrial EVs, which can drive various types of motors, including induction motor (IM), permanent magnet (PM) motor, and BLDC motor, so the CR Series can be integrated with various systems.

There are several hardware design features in CR Series. The use of low-loss MOSFETs and the increase of PCBA copper thickness lead to high performance and efficiency of the controller, which improves the driving range and alternatively saves initial battery cost. The metal core PCB (MCPCB) design in CR Series provides better thermal conductivity that helps the cooling of the controller. Its safe electrical insulation guarantees to withstand breakdown voltage up to 1500Vac.

CR Series features a comprehensive allocation of multi-function I/O including analog inputs, digital inputs, contactor coil drivers and proportional valve drivers. The CAN 2.0B interface connection allows communication with other devices.

A field-oriented control (FOC) technique is implemented in motor control to provide fast response. Its SMARTuning® software, with auto-tuning function, enables users to optimize new system applications to perform the motor characterization in place at less cost and time to the market.

The compact size of the controller makes it easy for system integration, and its robust design, with high IP rating, enables the motor controller to operate in a harsh environment. CR Series is designed and manufactured at the utmost quality to meet performance, safety, and reliability requirements.
