Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. In addition, the technical features of the embodiments of the present application described below may be combined with each other as long as they do not collide with each other.
The charging system involves a plurality of systems including a vehicle controller VCU, BMS, OBCDCDC, CCM and various charging posts. Because of the system
Incompatible, easily lead to charging and appear charging interruption, circumstances such as insufficient charging.
The application fully analyzes the reason of the charge interruption, forms a charge detection and fault tolerance method of a system, and reduces the charge interruption probability.
The scheme comprises analysis of each charging interruption reason, forms a charging detection and fault tolerance method of a system, and reduces the charging interruption probability.
In the actual use process, the following problems often occur:
1. problems: in the charging process, when the charging pile is poor in network signal, communication with a background cloud service cannot be achieved, and therefore timing cannot be achieved. When the charging pile cannot count time, the charging pile cannot charge, so that the charging pile is actively disconnected, namely the charging is interrupted.
The solution is as follows: the charging timing module is additionally arranged in the vehicle, when the charging pile is poor in network signal, the vehicle internal charger and the charging pile are in timely communication, the timing module is started, and timing information is sent to the charging pile. When the charging pile receives the timing information, the in-car charging timing module can be adopted, so that the charging pile does not stop outputting electricity and does not stop charging. The interaction signals of the charging pile and the in-vehicle charger comprise charging current, charging power and charging time. When the network signal is recovered, the charging pile informs the in-vehicle charger through communication, takes over charging timing, and continues charging until the charging is completed.
2. Problems: in the charging process, the charging pile is unstable in output voltage due to fluctuation of a power grid, so that the transmitted CP duty ratio does not meet the national standard requirement. And the in-vehicle charger detects that the received CP duty cycle signal does not meet the national standard requirement, thereby stopping charging.
The solution is as follows: in the charging process, the CP duty ratio is not directly detected, the output voltage value is detected, when the output voltage value of the charging pile is unstable, smoothing treatment is carried out through a transformer, burrs are reduced, and chopping is carried out. The charger thus performs smoothing processing on the input voltage to give a current of a stable voltage to the battery.
3. Problems: when normal charging process, the CC resistance of charging mouth and rifle junction that charges is detected to the machine that charges to ensure that rifle and vehicle charge mouthful connect closely, in order to prevent that charging mouth and rifle do not connect closely, last to charge, lead to the mouth of charging overheated. However, the vehicle is not actually connected in an untight manner because the vehicle is in an excessively long use time, which results in deformation of the connection structure between the charging port and the charging gun, but the vehicle is detected solely according to the resistance value of the charging port CC, and cannot judge whether the connection is truly disconnected, so that the possibility of mistakenly disconnecting the charging is increased.
The solution is as follows: in the charging process, the voltage detection at the two ends of the charging port is increased, and the voltage difference and the contact resistance value at the two ends of the charging port are calculated, so that the heating power is calculated. When the CC resistance value is wrong, the heating power is smaller than P1, namely the contact is considered to be good, and the charging does not need to be disconnected. The heating power exceeds P1, namely the heating power is considered to be overlarge, and the connection has a problem, namely the charging is disconnected. This scheme can reduce the possibility of charge interruption due to misjudgment of the connection state.
