Present electric car function is increasing, the odds that the function jumps over much occurrence trouble is bigger, how is if back a car,functional occurrence breakdown maintained?
Of electric car back a car device is by there is an electrical wiring to join through switch in controller electric machinery, fulfil electric machinery contrary to reason or one's expectation through electric current. The principle of the engine contrary to reason or one's expectation of its principle and car is same. Because electric car backs a car,the module that the function is controller interior is handled, join the switch that back a car comes true. Should back a car functional invalidation, should be below a few problems:
1, back a car the line was broken. Back a car the line is finer, use for a long time break easily, the line is broken, back a car the function can be lost.
Maintain a method: Change the line or receive afresh on.
2, back a car switch became bad. The use frequency of switch is very tall, will for a long time be answered back and forth meet bad by hard to avoid, the sheet copper inside worries head of thin, ageing, rusty, wiring sealing off, corrode into aquatic rust, bedspring card is buckled rupture, wait a circumstance a moment to be able to bring about a contact undesirable, do not have reaction by switch.
Maintain a method: Change ongoing and regressive switch or timing whole change.
3, controller is bad. As a result of the signal that back a car be by controller administer, once controller became bad,back a car of course cannot come true.
Maintain a method: If controller interior appears,back a car to be able to change directly unusually controller. Controller must have been secured, lest bump became bad.
4, back a car receive plug-in unit the contact is undesirable. The electric circuit on electric car has a lot of to receive plug-in unit, interior is brought about to receive in time plant insert sheet copper oxidation to be corroded, back a car especially receive plug-in unit sheet copper thin not anti-corrosive, when sheet copper contact is less than another plug-in unit, can appear back a car not to pour a phenomenon!
Maintain a method: Will back a car receive plug-in unit to secure do not touch to opposite person, the place that water does not drench, it is OK to receive plug-in unit to join reoccupy insulation adhesive plaster perhaps is plunged into take consolidate.
