Since photovoltaic energy is seriously affected by climate and the power conversion rate is not high, judging from current technology, there is still a long way to go before it can be used. apply to electric vehicles. will be completely replaced by graphite. It was replaced by new energy production such as ethylene. At present, it is the most ideal for installing a range extender on an electric vehicle. At least it can ensure that your electric vehicle can continue to operate. move forward when running out of power and won't stop halfway while waiting for a tow truck.
Recommendations for using range extenders for electric vehicles:
It is not recommended to start the range extender when the battery is full. It is generally recommended to start the range extender when the batteryie is loaded. only 30 to 40%. The best. There is no particularly good effect when starting when the battery is full. To protect 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. The range extender starts electrically. It may not start when the battery is low.
It's unrealistic. Don't even think about two wheels. The 4-wheel version can be placed on the roof, but it is currently impossible to meet your requirements. Select the panel based on the length and width of the roof. The greater the power, the greater the volume. The area of a piece of polycrystalline 50W18V is 67*54 centimeters. How many coins can you put in your car? The 60 V requires only five bat cards18 V battery are charged in series. The maximum charging current is only about 2.3 A. If the sun is small, it may only be a few tenths of an amp. According to the maximum charging current of 30/2.3 = 13 hours, it can be fully charged.
Taobao now also has charging cards for 48-72V trams. The area of 90V (charging 60V batteries) and 120W is 100*86 cm. 120/90=1.33A, 30/1.33=22.5 hours for a full charge. Two blocks in parallel, the time is divided by two, three blocks and four blocks... and so on. But this is calculated at the maximum hourly solar current, and the actual charging time will be approximately twice as long, depending on the sunshine value.
