The maintaince of the electric powered bicycles

Battery electric cars as transportation means of transport has been popular, it was discovered that every winter a large number of electric vehicle battery capacity has shrunk over the summer, or it becomes difficult to charge, and even fail to start. In fact, this is because many consumers ignoring the winter for battery maintenance. Reporters visited the capital of several  electric recumbent trike repair shop for electric car battery maintenance to understand.
Saihan an electric car repair shop maintenance staff, told reporters that the battery optimum working temperature of 15 degrees Celsius to 40 degrees Celsius. Outside this temperature range, it will affect the normal operation of the battery, the battery life will be shortened. A normal lead-acid battery can ensure that vehicles travel the farthest distance of 50 km, due to thermal expansion and contraction principle, the ambient temperature at -10 degrees Celsius, the battery power is not one hundred percent release, winter mileage than full power once the summer full power to reduce a lot of mileage. So for battery maintenance is very important.
First of all aspects of the charge after every home, regardless of the length of time, should be charged, to keep the battery at full power use state, if not the occasional little effect on the battery is fully charged, but often do not fully charged, the battery will produce a "memory" of the impact it continues the course, but also loss of battery life. First insert the battery charging plug, plug the power plug. Charging is completed, first pull the power plug, and then pull the battery plug.

Second, start the electric trike bicycles, avoid large current discharge, reduction manned exercise, when climbing or help implement the best human riding, otherwise a great damage to the battery. If a vehicle is parked in the open air or cold storage when not in use for several weeks, remove the battery and store in a warmer room, to prevent freezing damage to the battery. And when the temperature is too low to try to shorten the duration of use of electric vehicles, and should be promptly charged. If you do not plan to use in the winter car batteries, rechargeable batteries should not have been put to use during the coming year, and every one should be charged once a month to battery power, to ensure that the lead-acid battery storage capacity, while avoiding the acid spill damage battery. Maintenance staff, said maintenance charge the battery to remember to wash, more power.
Six months after use, it is best to do a battery maintenance service points, appropriate complementary battery electrolyte, the electrolyte adjusting the proportion of good and check deposit of electricity to keep the battery electrolyte specific gravity, if necessary, to increase the number of charges. Also, clean the battery terminals and apply special grease to protect is also important when it ensures effective and reliable electric car start, prolong battery life

Chinese standard of electric bicycle

electric recumbent trike main four national standards: there must be a foot to achieve human riding; maximum design speed of not more than 20km / h; vehicle quality is not more than 40kg; motor output power less than 240w;
National standards, "General Electric Bicycle technical conditions" (GB17761-1999)
Electric Bicycle (electricbicycle)
With batteries as auxiliary energy, with two wheels, to achieve human riding, electric or electric-assisted bicycles special features.
Technical requirements:
1. Top speed: should not exceed 20km / h; ("Exchange Act" 58 stipulates that the electric car a top speed of no more than 15 km)
2. The quality of vehicle: not more than 40kg (including battery);
3. Foot driving ability: You must have a good foot riding function, 30min foot travel distance should not be less than 7km;
4. Continues the course: After a charge to continue the mileage should be not less than 25km;
5. Maximum riding Noise: When the maximum speed for electric uniform riding (motor assist to 15km / h ~ 18km / h speed electric assisted riding) noise should not exceed 62dB (A); 100km of power consumption should be less than 1.2kW · h;
6. One hundred kilometers power consumption: with electric ride (electric power to electric assisted riding), 100km of electric power consumption should not exceed its own 1.2KWH
7. Motor power: rated continuous output power should not exceed 240W;
8. Braking performance: maximum speed when riding electric (power assisted to 20km / h speed electric assisted riding), its dry braking distance should be less than 4m, wet braking distance should not exceed 15m.
According to the State in 1999 to develop common standards for the relevant provisions of the design maximum speed, empty quality dimensions, the electric bicycle ownership of non-motorized management areas, should also have the following five characteristics: You must have foot traffic function, the battery only as a auxiliary energy; must have two wheels; the design speed of not more than 20 km / h; vehicle weight of not more than 40 kg; tire width (the womb) is not greater than 54 mm.
electric powered bicycles models with TD (special kind of bike electric bike class) cap number. Although it looks characteristics (physical features even have a motorcycle) ordinary bicycle, but the main thing is that it is based on an ordinary bicycle, the installation of motors, controllers, batteries, turn the brake components to manipulate and display, etc. electromechanical instrument system integration, personal transport.
Foreign standards
As the global voice for sustainable development continues, green energy has become the theme of the times. Low-carbon, low travel tools become the darling of the new era of people around the world. Should the occasion, the rapid development of electric vehicles, and soon swept the globe. To facilitate the management of the regions and countries of the electric car has a different management and import standards, China as the most technologically advanced and largest regional exports, a comprehensive understanding of the various areas of electric vehicles defined standard is very important, in this writer for Solo part of the majority of manufacturers such as: electric cars standard parts of the United States, Japan and Taiwan.
