Lithium battery for low speed electric vehicle
Before purchasing a lithium battery, check whether the battery cells used are grade A. The quality of the battery cells determines the quality of the battery, for example as capacity and energy density. Wait, second, find a lithium battery produced by a major manufacturer with mature production technology and guaranteed after-sales service. The market reference price of lithium battery is 1,250 yuan/KW.H. If you have to travel a long distance, it is best to install a range extender. With it, you won't be afraid of running out of energy halfway and it can help you travel worry-free.
Since the cruising range of low-speed four-wheel electric vehicles is still relatively limited and cannot fully meet the daily travel needs of the public, if you wishIf you want to increase its cruising range, you can install an extended range. Increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and travel back and forth freely, without more difficulty due to lack of power midway.
You can buy the range extender directly from the manufacturer, and they will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a major manufacturer and a major brand to have all the guarantees in terms of quality, performance, manufacturing and after-sales service. Otherwise, if it is a small workshop type manufacturer, it will be easy to break and there will be no guarantee in all respects.
Recommendations for using the range extender:
It is not recommended to start the range extender when the battery is full. HeIt is generally recommended to start the range extender when the battery is only charged. 30%-40%. There is no particularly good effect when starting when the battery is full. For the sake of respect for the environment, it is recommended to start the range extender when necessary. Battery pollution is more serious than exhaust pollution. It is not recommended to use it when the battery is low on electricity. The range extender starts electrically. If the battery is low on electricity, it may not start.
Price of old lithium batteries for electric vehicles
The new specification price of Gaomai Zhixin 60V20AH lithium battery is about 16xx yuan, and the trade-in price is 14xx yuan and the warranty period is 5 years (guaranteed replacement for the first 3 years and warranty for the next 2 years), with a costannual average of 3xx yuan. It has strong power, long service life and no mileage anxiety in 3 years. It is undoubtedly the most profitable.
Technical parameters:
1. Machine model: GD-1109-80, -120.
2. Applicable voltage: AC ±5%/50HZ.
3. Maximum power: 16KW.
4. Applicable power: air compressor.
Effects on battery/capacitor performance:
1. Removes battery polarization, reduces thermal effects and improves flow performance;
2. Reduce battery internal resistance and significantly reduce the increase in dynamic internal resistance during cycling;
3. Improve consistency and increase battery life
4; . Improve the active material Adhesion to the current collector reduces the manufacturing cost of the pole piece;
5. Protects the current collector from corrosionby the electrolyte; high and low temperature performance of lithium iron phosphate battery performance, improving the phosphoric acid processing properties of lithium iron and lithium titanate materials.
