Lithium battery electric bicycles refer to the mechatronics personal electric vehicles that use lithium batteries as auxiliary energy sources and are equipped with the operating components such as motors, controllers, batteries, brake handles and display instrument systems.

Charger is to recharge the battery power device, generally divided into two stages of charge mode and three stage mode two. Two-stage charging mode: constant voltage charging, the charging current decreases with the rise of the battery voltage, the battery voltage to a certain extent, the battery voltage will rise to the charger's set value, this time converted to trickle charge. Three-stage charging mode: charging starts, the first constant current charging, quickly to the battery replenishment of energy; waiting for the battery voltage rose to constant voltage charging, the battery energy slowly added, the battery voltage continues to rise; to the charger charge termination voltage Value, to trickle charge to maintain the battery and battery self-discharge current.

Battery is to provide electric energy vehicle energy, lithium battery electric vehicle is the latest type of lithium-ion battery.

Hint: The main control board of the controller is the main loop of the electric vehicle, which has a large working current and will generate more heat. Therefore, electric cars do not park in the sun exposure, do not prolonged rain, in order to avoid controller failure.

1 below the average wholesale price of the battery firmly not buy.

2 did not have more than 2 years of market test products.

3. There is no electric car manufacturers with the car firmly not buy the battery.

4. High-priced battery, if not produced by Dachang, firmly not buy.

5. Change the national standard size of the battery firmly not buy.

6.5A discharge, 30 seconds when the voltage is higher than 12.68V of the firm do not buy, 90% of the short-lived battery.

The easiest way to detect the battery: 5A discharge, 30 seconds when the voltage is lower than 12.63, the first three minutes of voltage rise and fall, the more the reverse, the better the quality.
