Important note correct use of electric vehicles project a day before moving to check the adequacy of power, braking performance is good, the screws are loose, etc., should be repaired exclude faulty check is completed in order to make sure that no fault of the bus; 2, charging section When the repair or replacement of three-wheeled electric vehicle charging fuse, you must unplug the power cord 220V, are not allowed to live work; 3, each park must turn off the power switch, remove the key, the gear switch to the neutral position, and Pull the handbrake; electric tricycle 4, to prevent exposure temperature environment will increase the internal pressure of the battery battery pressure limiting valve forced open automatically, is a direct consequence of the loss of water to increase battery electric passenger three, and excessive loss of battery water will inevitably lead to decreased cell activity, accelerating the plate to soften the shell three electric heat, from the drum shell, deformation fatal injury while charging. 5, to avoid heating the charger output plug loose plug charging, the contact surface oxidation, and other phenomena can cause charging plug fever, fever too long will lead to a short circuit charging plug directly damage the charger, lead to unnecessary losses. When it found out that the case should be promptly removed oxide or replace the connector. 6, in the course of regular inspections, if the electric car to continue the mileage sudden drop ten kilometers in a short time, it is likely that the battery pack at least one battery has broken grid, plate softening, electrode active material shedding short circuit. At this point, it is timely to specialized cell repair mechanism to check, repair, or with a group. This can extend the life of the battery pack relative to maximize savings.
