It depends on the circumstances:
1. This is not illegal, but if there is a safety hazard that causes injury to others, you will be liable for compensation.
2. Illegal. If the electric vehicle is converted to a lithium battery that does not meet the rated voltage, it is illegal if the battery model is different.
Illegal modification of electric vehicles:
1. Modification or modification of the engine so that the engine exceeds the factory set horsepower rating of the original vehicle
>2. Modification or modification Remove the speed limiter and pedal driving equipment;
3. Remove the speed sound device
4. does not meet the factory set voltage rating of the original vehicle battery;
5. Install an umbrella stand and car hood.
6. Unauthorized spraying, installation and use of vehicle logos, sirens and lightingspecial or similar vehicles.
Legal basis:
Points (3) and (4) of Article 119 of the “Road Safety Law” were clear definition was manufactured on "motor vehicles" and "non-motor vehicles", i.e. "motor vehicles" means wheels driven or towed by electrical appliances and driven on the road for people to ride on or to transport objects and carry out special engineering operations. .vehicle type. “Non-motorized vehicles” means vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs and electric bicycles for disabled people which are driven by electrical devices but have a designed maximum speed, quality of empty vehicle and external dimensions comply with current national standards. Waiting for transport.
Article 14of the Shenzhen Electric Bicycle Management Regulation prohibits the following actions on electric bicycles after sale:
(1) Adding or modifying electrical devices such as electric motors and batteries, or replacing food. devices such as motors and batteries that do not meet national standards;
(2) Addition or modification of hoods, compartments, seats and other devices affecting safety;
( 3) Disassembly or modification of the speed limit processing device;
(4) Laws and regulations stipulate other assemblies, renovations and other modifications that affect the safety of electric bicycles.
Article 18 of the “Regulations on the Administration of Electric Bicycles in Zhejiang Province” stipulates that if a modified, assembled or upgraded electric bicycle is driven on the road, the traffic management department of the public safety organization confiscal the assembled vehicle and order the reinstatement of the speed limit. Installing, dismantling, adding or modifying devices driving an electric bicycle with the speed limiter removed or modified, resulting in exceeding the maximum speed compared to the mandatory national standard, a fine of at least a fine of at least 300 yuan but not more than 500 yuan will be imposed; driving with other modifications, assemblies or additions. Those who use electric bicycles under certain circumstances will be fined at least 50 yuan but not more than 300 yuan.
Can the original lead-acid battery of an electric bicycle be replaced with a lithium battery?
It can be replaced by a 48V10A lithium iron phosphate battery. The details are as follows:
1. Remove the battery from the electric car. There is a battery lock on the side. of the car. Please use the battery. AfterAfter unlocking the door key, remove the battery.
2. Unscrew the four corner screws and carefully open the top cover. You can see that there are four 12V lead acid batteries inside. There is no bulge in the battery condition.
3. The battery circuit is connected in series. The red wire and brown wire are connected to the positive electrode of the battery. The red wire is connected to the discharge port of the battery box. a small black tube on it for the fuse. The brown wire is The wire is connected to the positive pole of the charging port, the blue wire is connected to the negative pole of the battery, the thicker wire is connected to the discharge port, and the thin blue wire is connected to the negative pole of the charging port. Don't forget the color of your battery wiring, which is relatively simple.
4. Next, use a soldering iron to remove the battery wires. Be careful to prevent the batterydoes not short circuit during operation.
5. After removing all the old batteries, insert the lithium battery. When installing the battery, there are some small protruding plastics inside to separate the original lead acid batteries. The battery wiring is. not soldered, and the battery Connect the connector terminals and wrap it with insulating tape.
6. The wires are connected and you are almost done. Then you can sort out the wiring, put the outer cover back on and tighten the screws. After charging and testing, charging and use are completely completed. normal.
You can replace it with a lithium battery, but you must replace it with this highly safe lithium iron phosphate battery, which is characterized by its resistance to high temperatures and no risk of explosion. Points to consider when replacing the battery are:voltage of the new battery should be the same as the original one, and if the height and width of the new battery can match the original car when replacing batteries of different types, the corresponding charger should be matched in the future
