The connection method of the battery of an electric bicycle varies depending on the number of batteries and the model. The following are common wiring methods and precautions:
1. Wiring method for four batteries
Wiring method: Use series connection, starting from the negative pole of the first battery, connect to the positive pole of the next battery in sequence, connect the positive pole of the last battery to the positive pole line of the electric vehicle, and the negative pole of the first battery to the negative pole line of the electric vehicle.
Advantages: Save wire and avoid line pressure.
2. Wiring method for five batteries
Wiring method: Similar to four batteries, use series connection to ensure that the positive and negative poles of each battery are correctly connected, and finally connected to the positive and negative poles of the electric vehicle.
Precautions: Reasonable layout to avoid excessive compression of the line.
3. Wiring method for six batteries
Wiring method: Divide the six batteries into two groups, connect three batteries in series in each group, then connect the two groups in parallel, and finally connect to the positive and negative poles of the electric vehicle.
Advantages: Ensure the stability and safety of the battery system.
4. Switching method of two sets of batteries
Plug conversion method: Connect the two sets of batteries separately and switch them through elbow wires to avoid using two sets of batteries at the same time to extend battery life.
Air switch switching method: Connect the positive poles of the two sets of batteries to one end of the two air switches respectively, and connect the negative poles with wires and connect them to the negative pole line of the electric vehicle. The battery pack can be replaced by switching the air switch.
5. Wiring method of 12 batteries
Wiring method: Divide the 12 batteries into two groups, each with six batteries connected in series, and then control the switching of the two sets of batteries through two air switches.
Advantages: Flexible switching of battery packs to extend battery life.
6. External battery method
Electric bicycle style: Use an elbow wire and battery socket, red wire to red wire, black wire to black wire.
Electric motorcycle style: Use two elbow wires, red wire to red wire, black wire to black wire.
7. Precautions
Safety first: Turn off the power before wiring to ensure there is no short circuit.
Check the circuit: Use a multimeter to test whether the circuit is unobstructed and ensure that the connection is firm. Avoid wire crimping: Arrange the wires reasonably to prevent wire wear and fire risks.
