Warm control module 953, it is communicated to connect with current sensor 93, voltage sensor 94 and temperature sensor 92 respectively.The mistake
The crossfire electric current that flow control module 951 is used to detect current sensor 93 is compared with predetermined current, in crossfire
Electric current is judged when being higher than predetermined current there occurs excessively stream, has at this moment been likely to occur battery and has completely been filled or overcharge, therefore the excessively stream
Control module 951 will control the charging contactor 91 to turn off.The over-pressed control module 952 is used to examine voltage sensor 94
The crossfire voltage measured judged there occurs overvoltage compared with predeterminated voltage when crossfire voltage is higher than predeterminated voltage,
At this moment it has been likely to occur battery completely to fill or overcharge, therefore the over-pressed control module 952 will control the charging contactor 91
Shut-off.The excess temperature control module 953 is communicated to connect to receive the real time temperature of each lithium battery with each temperature sensor 92.
The excess temperature control module 953 by each real time temperature received respectively compared with preset temperature, in any one reality
When Shi Wendu is more than preset temperature, the charging contactor 91 will be controlled to turn off.
In the simplification embodiment of the present invention, can only it set in flow control, overvoltage control and excess temperature control at least
One or both.Certainly in a preferred embodiment of the invention, it is proposed that as described above, being controlled to three.In the present invention
In, it can realize that above-mentioned flow control module 951 excessively, overvoltage control using known any comparison circuit, module or device
Module 952 and excess temperature control module 953.
Implement the electric automobile with charging safety of the present invention, by detecting the contact between cradle and charging plug
State, so as to start parking control, so as to avoid car owner forget automobile charging just rashly start vehicle by car start go
Sail, efficiently avoid accident.Further, car owner is avoided to forget charge closing flap and filling by voice reminder
It is close when electric, ensure the charging safety of electric automobile.Yet further, by detecting the electric current, voltage and/or temperature of battery
Degree, and powered off rapidly in excess temperature, overvoltage and/or excessively stream, Additional Protection has been carried out to battery, has substantially increased electric automobile
