Main parts of electric bicycles
Charger is to recharge the battery device, generally two-stage charging mode and three-stage mode. Second-stage charging mode: the first constant voltage charge, charging current with the increase in battery voltage gradually reduced, such as the battery charge to a certain extent, the battery voltage will rise to the charger set value, at this time to trickle charge conversion. Three-stage charging mode: When charging begins, first constant current charge, quickly to replenish the battery energy, and so on, when the battery voltage increases to a constant pressure charge, at this time the battery energy slowly supplemented, the battery voltage continues to rise, to reach the charging termination voltage value of the charger, into trickle charging to maintain the battery and the self-discharge of the battery.
Battery is to provide the energy of electric vehicles with the vehicle energy, electric vehicles mainly using lead-acid battery combination. In addition, Ni-MH batteries and lithium-ion batteries have also been used in some light folding electric vehicles.
Use TIP: Controller main control Board for the main circuit of electric vehicles, with a large operating current, will emit greater heat. Therefore, electric vehicles do not park in the sun exposure, also do not long rain, lest the controller out of trouble.
Controller is the control of motor speed components, but also the core of electric vehicle electrical system, with undervoltage, current-limiting or overcurrent protection functions. Intelligent controller also has a variety of cycling mode and the electrical components of the vehicle self-test function. The controller is the core component of electric vehicle energy management and various control signal processing.
