As shown in figure 15, and Figure 12 is combined, the flow that main road battery is switched to bypass battery comprises the following steps：

Step S1501, closes K1 first, and main battery major loop is connected, and system access is that main road battery (actually only has main road Battery is accessed, and can just be switched to bypass, what actual K1 was originally closed), now arrange upper voltage and main road cell voltage phase Together；

Step S1502, closure main road battery accessory channel contactor K2；

Step S1503, K1 disconnection, now main road battery is by accessory channel access system, when the upper voltage of row is (between L+ and L- Voltage, i.e. DC power supply output end both end voltage) be more than main road cell voltage when, diode VD1 is not turned on, main road electricity Neither charge nor discharge in pond.When exchange has a power failure or the upper voltage of row is less than main road cell voltage, VD1 is turned on, and main road battery can be with Prevent that power supply is abnormal in battery handoff procedure or exchanges the generation of the situation of power failure load power down to load discharge；

Step S1504, closes bypass battery accessory channel D.C. contactor K4, and now major-minor battery is all accessed by accessory channel, Due to VD1 and VD2 presence, battery channel conductive in electric discharge, is not in due to battery caused by major-minor battery pressure difference Mutually fill, be also not in power supply while situation about being charged to battery, is not in that the upper voltage of row and bypass battery pressure difference are excessive The situation of over-charging of battery occurs；

Step S1505, disconnects K2, and now bypass battery is by accessory channel access system, when the upper voltage of row is more than bypass battery During voltage, diode VD2 is not turned on, and bypass battery neither charges nor discharged.When exchange has a power failure or arranged upper voltage less than bypass VD2 is turned on during cell voltage, and bypass battery can prevent that power supply is abnormal in battery handoff procedure or exchanges to load discharge The situation of power failure load power down occurs；

It is excessive much larger than auxiliary for the upper voltage of the row of preventing before bypass battery main channel K3 is connected under step S1506, current state Road cell voltage causes K3 to connect moment over-charging of battery, now adjusts power supply output voltage, makes the upper voltage of row close to bypass electricity Cell voltage.When exchange has a power failure or power supply unit is abnormal without output, now bypass battery directly by accessory channel to load discharge, Voltage can directly can be close to bypass cell voltage on row；

Step S1507, now whether CSU detection bypasses cell voltage is close with the upper voltage of row, close then execution step S1508, Otherwise S1506 is performed to continue to adjust power supply output voltage；

Step S1508, when the upper voltage of row is approached with bypass cell voltage, moment power supply is connected to bypass battery mistake without K3 Risk is filled, K3 is now connected, bypass battery major loop is connected, bypass battery major loop access system；

Step S1509, now disconnects bypass battery accessory channel, disconnects K4, and the formal access system of bypass battery completes main road Battery is to bypass battery switching flow.

Be not in that main and side road battery occurs by the situation of main channel directly access system discharge and recharge simultaneously in whole handoff procedure. Bypass battery is switched to main road battery flow and is switched to bypass flow just in turn with main road, as shown in figure 16, with reference to Figure 12, The flow that the main road battery is switched to bypass battery includes：

Step S1601, closes K3 first, and auxiliary battery major loop is connected, and system access is that bypass battery (actually only has bypass Battery is accessed, and can just be switched to main road, what actual K3 was originally closed), now arrange upper voltage and bypass cell voltage phase Together；

Step S1602, closure main road battery accessory channel contactor K4, it is ensured that 603 disconnect after K3, when the unexpected power down of system When, bypass battery can be to load temporary power by diode by accessory channel；

Step S1603, K3 disconnection, now bypass battery is by accessory channel access system, when the upper voltage of row is more than bypass battery During voltage, diode VD2 is not turned on, and bypass battery neither charges nor discharged.When exchange has a power failure or arranged upper voltage less than main road VD2 is turned on during cell voltage, and bypass battery can be to the of short duration electric discharge proof load not power down of load；

Step S1604, closes main road battery accessory channel D.C. contactor K2, and now major-minor battery is all accessed by accessory channel, Due to VD1 and VD2 presence, it, because major-minor battery mutually fills, is also not in that power supply charges to two-way battery to be not in Situation；

Step S1605, disconnects K4, and now only main road battery is by accessory channel access system, when the upper voltage of row is more than main road electricity During cell voltage, diode VD2 is not turned on, and bypass battery neither charges nor discharged.When exchange has a power failure or arranged upper voltage less than auxiliary VD1 is turned on during the cell voltage of road, and main road battery can prevent that power supply is abnormal in battery handoff procedure or hands over to load discharge The situation for flowing power failure load power down occurs；

Under step S1606, current state, before main road battery main channel K1 is connected, sent a telegram here suddenly for anti-locking system, it is electric on row Pressure causes K1 connection moment main batterys to overcharge much larger than main road cell voltage, now adjusts power supply output voltage, makes the upper electricity of row Crimp nearly main road cell voltage.When exchange have a power failure without output when, now main road battery directly by accessory channel to load discharge, Voltage can directly can be close to main road cell voltage on row；

Step S1607, now whether CSU detection bypasses cell voltage is close with the upper voltage of row, close then execution step S1608, Otherwise S1606 is performed to continue to adjust power supply output voltage；
