Two bidirectional charger families: the proven BiDC series (X1 / X2 / X3, covering 12V/24V vehicles) and the new-generation CiDC series (X1 = 40A · X2 = 60A / 1500W). Charge the house battery efficiently while driving; automatically recharge the starter battery when parked. One device covers charging, power supply and rescue.
Request a QuoteNext-generation vehicle bidirectional chargers: while driving, the Star (starter) battery charges the House battery with CC-CV high current; when parked, it recharges the starter battery in reverse. CiDC-X1 (40A) and CiDC-X2 (60A / 1500W flagship) share the same bidirectional charging/discharging, 4 work modes and protection strategy. 12V/24V/48V universal, compatible with Euro 5/6 and China 5/6 smart alternators.
The 40A grade, fully verified by a third-party inspection report (conclusion: PASS). Indicator-panel housing with three-color Power / Forward / Reverse status LEDs and an ON/OFF rocker switch; exposed ACC terminal — status readable at a glance.
60A / 1500W bidirectional fast charging for large house batteries and high-load conversions. RC-control-port housing with a reserved port for the remote LCD panel and Forward / Reverse / Alarm silkscreen areas — ideal for hidden installation.
X1 parameters are from third-party inspection measurements; X2 flagship parameters follow the official datasheet.

Switched via CONTROL-port wiring + ACC state, covering driving charge, parked reverse-charge and long-term storage scenarios.
| Mode | ACC | Key Switch | Behavior |
|---|---|---|---|
| Mode 1 | ON | — | Star battery charges House battery via CC-CV (driving charge) |
| Mode 2 | OFF | I | Star→House charging continues; auto-stops when Star drops below 13.5V (12V) / 27V (24V) |
| Mode 3 | OFF | Off | Standby, lowest static draw: 12V/24V <0.01W · 36V/48V <0.04W (for long-term storage) |
| Mode 4 | OFF | II | House→Star reverse charging; auto-stops when House drops below 13.5V (12V) / 27V (24V) |
BiDC-X1 / X2 / X3 share the same bidirectional charge/discharge platform. All three support 7 work modes, SOS emergency rescue and IGN(ACC) intelligent control.
Full bidirectional platform at the entry grade — ideal for single-battery, simple-load conversions.
Enhanced bidirectional control logic: charge/discharge direction follows IGN(ACC), better matching vehicle electrical logic.

Forward charging, reverse feeding, temperature derating and SOS rescue work together automatically — no manual intervention after installation.
| Condition | Action |
|---|---|
| ACC = ON (6–32V) | LS → HS + Load (12V): forward-charges the house battery while powering 12V loads |
| ACC = OFF | HS → LS + Load (12V): reverse output 13.2V recharges the starter battery with load support |
| Starter voltage < 12.2V | Charges to 13.2V, then re-evaluates ACC state |
| Reverse charge 30 s | Disconnects from the starter battery to avoid continuous back-feed |
| SOS button | Performs emergency charging rescue on the starter battery |
| SOS exit | Voltage reaches 13.2V / ACC turned on / 1 hour elapsed — any one condition exits |
