![]() ![]() A conventional "jump start" from another vehicle will solve the problem. As these are usually 12 volt relays, an EV with a dead service battery will be immobile since no voltage will be available to pull in the relays - even though the traction pack is fully charged. ![]() The converter will then provide enough power to close the relays, even while the battery is being charged. Some means of operating the converter to recharge a dead auxiliary battery may be provided using a separate push-button for emergency bypass of the converter relays. A system that is float charged for long periods could include a separate 12 volt float charge device, sold for use with vehicles that are infrequently driven. If the usage pattern for the vehicle includes long times at rest with automatic (timed) recharge you may find it desirable to activate the converter during the charge cycles. A typical installation will only charge the battery through the DC-DC converter when the vehicle is in operation. The battery should be large enough to provide several hours of emergency flasher or parking light use, a requirement that may be beyond the capabilities of a motorcycle battery. The addition of a 12 volt battery of modest size greatly simplifies satisfying the basic electrical requirements of the vehicle and allows a relatively small capacity DC-DC converter to be used, since this need not supply peak current requirements. ![]() The additional space may be used for an EV component such as a power brake booster pump or the 12 volt converter that keeps this battery charged. Using an auxiliary battery Ī much smaller battery may be used as it is not necessary to crank an ICE to start it, so the large battery may be replaced with a motorcycle, garden tractor or similar battery with much less weight and capacity of that which came with the car. This low voltage is also used to control both low and high voltage relays required by the EV conversion. The twelve volt system is maintained to operate the headlights and various running lights, instruments, radio, heater fan, and other components common to the ICE vehicle. Note: The unit must be unplugged before switching output voltage from 110 to 240 volts.Vehicle service electrical system Be sure to check any wattage or voltage requirements for using your car’s 12-volt DC lighter. USB and universal AC plug ports can be used simultaneously within the unit’s 350-watt limits. Ideal uses for this power inverter include laptop (MacBook, Chromebook, Dell) chargers, DVD players, and electrical/electronic devices that can be used safely in a car. Additional features include power-on and error/fault LED indicators, overload protection via two 30-amp fuses (one for 110 volts use and 240 volts use), an onboard cooling fan, and a 24-inch (including plug) connection cable. The 350W Power Inverter features a universal outlet receptacle compatible with plug types used throughout the world (except Type D plugs used in South Africa), along with two 5-volt/3-amp DC USB ports. Voltage is selectable between 110 or 240 volts via a standard slider switch. ACUPWR 350-Watt Travel Power Inverter Converts 12-volts DC to 110 or 240-volts AC Ideal for Charging Laptops, Smart Phones, Tablets, Mobile DVD Players, and more via Universal OutletĪCUPWR’s 350-watt power inverter converts 12 volts of DC power to either 110 or 240 volts AC via a universal car lighter plug. ![]()
