Embodiment 1

[0070] refer to figure 2 , taking batteries B1 and B2 as an example, when VB1>VB2, turn on Q1, batteries B1 and L1 form a circuit ①, and the energy is transferred from B1 to L1 for storage. As shown in circuit ②, the energy of capacitor C1 is transferred to B2. When Q1 is turned off, D2 is forced to open, D2 forms a loop with B1 and C1 ③, battery B1 charges C1 through L1, D2, B2, and L1 form a loop ④, and the energy stored in L1 is transferred to B2. During this period, L1 is always in the state of transferring energy, and the current decreases. Through the balance module, the power balance between batteries B1 and B2 can be realized. When there are more batteries, the power balance of more batteries and even the entire battery system can be realized, thereby ensuring the power balance and balance of all roadside units. Compensation, even if there is a problem with the power system of an individual roadside unit, it will be compensated quickly so that it will not be affected...

Embodiment 2

[0072] refer to image 3 , image 3 Showing a perspective view of the antenna according to the present invention, the slot antenna 1 is formed by providing a reflection plate 3 on the back side of the antenna substrate 2, which is provided on the back side of the antenna substrate 2, and reflects radio communication waves radiated along the front, so as to To increase the gain of the antenna, the reflector 3 is formed by a component that effectively reflects electromagnetic waves of the corresponding frequency band. The wireless communication waves radiated from the antenna substrate 2 in the forward direction are in the same phase, and the microstrip line 9 is divided by the power divider 10 to form two parallel slots 11 and 12 .

[0073] Compared with conventional antennas, this antenna distributes wireless communication waves evenly on parallel lines with the same phase due to the above-mentioned specific structure, and transmits wireless communication signal waves from a ...
