SG158B Intelligent Brushless Electric Bicycle Controller solutions and products (48-60V/500W) 

 -------------------------------------------------- ----------------------------- 

 Operating voltage :48-60V Rated Power: 500W 

 Intelligent Brushless Electric Bicycle Controller Single-chip as the master chip, and leading software technology to control and protect electric car motors, batteries, electric cars work in the best condition. Controller's main features are: 

 1. Display: undervoltage / overvoltage status display, cruise shows, the controller fault status display, speed display. 

 2. Cruise features: point-acting, passive, automatic and manual cruise cruise two functions optional, 8 seconds into the cruise, steady speed, no need to handle control. 

 3. Power function: controller based on the current speed changes automatically given the appropriate proportion of the motor power, so cyclists feel more relaxed and comfortable. 

 4. Protection: 

 (1) hardware self-protection function: When the controller is powered, automatic self-MOSFET, if found in an instant power MOSFET damage, the controller is locked. 

 (2) stall protection function: automatically determine the electrical current in a normal operating state, blocking state or short-circuit state, running state, the controller output current at a fixed value, in order to maintain the vehicle's power; when the motor in a stall state, the controller 1 to 2 seconds after the auto power off, play a role in protecting motor and battery; when the motor is short-circuit condition, the controller will cut off power supply to ensure the safety controller and battery. 

 (3) power tube protection: the controller is running, real-time monitoring of the work of the power control, power management event of unusual circumstances, the controller immediately protected to prevent damage to other power tubes. 

 (4) phase protection function: When the motor Hall phase or phase sequence error (120 degrees then 60 degrees the motor controller or vice versa) when the control output will be turned off while the controller output signal specific instructions. 

 (5) Short circuit protection: When the motor phase short circuit or damage which way MOSFET, short-circuit protection function in a very short period of action, while the controller will output a corresponding fault signal. 

 (6) Anti-Speed ??function: When the controller to switch the power on if there is no return to zero, the controller will not start to address the brushless electric vehicle controller, or line failure due to switch to Speed ??caused phenomenon, vehicle security will be greatly enhanced. 

 5-phase current control: adjustable phase current size, to prevent the MOSFET MOSFET current exceeds the rating of the actual work, resulting in permanent damage to the MOSFET. 

 6. Synchronous rectification function: When the PWM is cutting the state controller's phase current is greater than a certain value, the synchronous rectifier is turned on, reduce heat and improve the reliability of the controller. 

 7. Flexible E-ABS system: an anti-charge / E-ABS brake function with E-ABS brake quiet, soft effect, and not damage the motor and mechanical braking force to reduce the mechanical brake pressure to reduce brake noise and increased vehicle brake safety. 

 8. Low-noise control features include: starting with E-ABS at low-noise control. 

 9. Anti-charging function: braking, deceleration or downhill slide will EABS the energy generated back to the cell, play a counter-charge effect, thereby maintaining the battery to extend battery life, increase continues the course. 

 10. Mode switching: automatic or manual cruise cruise selected, high and low settings according to user needs. 

 11. Self-learning function: This feature automatically identifies the phase, do not adjust the motor leads. 

 12. Parking features: electric tricycle can be used in the selection of reverse function. 

 13. Motor lock: lock user in the case of turning off the motor, the controller can automatically lock the motor, the controller only small current consumption, there are no special requirements on the motor, the battery voltage or other exceptional circumstances, the normal electric cars implemented without any effect.
