It charges；Conversely, the power-off of the battery management system 5 is stopped, the internal relay of the power battery 7 disconnects, institute
It states the power-off of DC/DC converters 6 to be stopped, the charging circuit between the power battery 7 and accumulator 1 disconnects, and system is again
Into dormant state, restart until detecting that power shortage state occurs in accumulator next time.
When practical control, preferably when the voltage of accumulator is less than 10.8V, the output end of the comparator is turned by high level
Become exporting low level, optocoupler is connected at this time, exports two path control signal；When the voltage of accumulator reaches at or above 13.8V,
The comparison circuit exports high level, and optocoupler disconnects at this time, stops control signal output.
This is because, utility model people has found by a large amount of experiment：After the voltage of accumulator 1 is less than 10.3V, key point
When fiery, DC/DC charging systems can not work normally, it is necessary to and DC/DC charging systems could be started by carrying out sparking with other batteries, and
The minimum 10.5V of conventional discharge voltage of 12V accumulators, error caused by component etc. in consideration system, by the electricity of accumulator
Pressure is set in 10.8V, prevents brownout from causing DC/DC charging systems that can not start, does not realize automatic charging function.Together
When, the actual output voltage of vehicle-mounted DC/DC is 14V, and detection circuit must trigger shutdown signal before reaching 14V, otherwise
The effect being automatically closed is not achieved, equally error is taken into account, shutdown voltage is set as 13.8V.
This patent further discloses a kind of electric vehicle, including the accumulator of electric car power shortage self-charging system
System, the electric vehicle can be the electric vehicle of known various types, brand, and details are not described herein again.
Still there are many embodiment, all technologies formed using equivalents or equivalent transformation for the utility model
Scheme is all fallen within the scope of protection of the utility model.
