Electric bicycle charging current as the rise of the battery voltage decreases gradually

Electric bicycle charging current as the rise of the battery voltage decreases gradually, such as battery after added to a certain extent, the battery voltage rises to the setpoint of the charger, when converted to a trickle charge. At the start of the three-stage charging modes: charge, constant current charge first, quickly to the battery energy; Such as battery voltage up to constant voltage charging, battery Three wheel bikes slowly added at this time, the battery voltage continues to rise; Reach a charger of the termination voltage value, converted to a trickle charging, in order to maintain the battery and the self-discharge of the battery supply current. Battery is to provide electric energy, energy, electric vehicles using lithium-ion batteries is the latest lithium ion battery.Use tip: loop controller for electric main control board owners, with large working current, have a large quantity of heat. As a result, electric cars do not park in the sunlight, also don't get wet in the rain for a long time, so as to avoid controller is out of order. Controller is to control the motor speed, also is the core of the electric car electric system, has under voltage, current limiting or Folding electric bikes protection function. Intelligent controller also has a variety of cycling self-check function model and vehicle electrical components. The controller is of various electric energy management and control the core component of signal processing. Turn, brake handle is the controller of the signal input part. Turn the signals is rotating electric motor drive. Brake when the signal is when the electric brake, brake handle internal electronic circuit output to the controller of an electrical signal; After controller receives the signal, will cut off the power supply of motor, so as to realize the brake power function. The electric bicycle motor is mostly used by high efficient rare earth permanent magnet motor, and points the mainly have among them brush + geared motor, brushless motors have brush motor at low speed and low speed three, now have brush + geared motor at high speed performance is best, the price is expensive; Low speed with a brush motor to cheaper, but the performance is poor; Brushless motor due to the high quality requirements of controller, listed on the brand is not much, ordinary consumers to buy when had better choose brand.
