For modern liquid cooled AC motors and inverters, often you will need separate cooling circuits as the inverter and motor operate in different temperature ranges.

It surprises many that you need liquid cooling in an electric car, but modern high powered IGBT power switching circuitry can be smaller, operate better, and last longer if it is liquid cooled.  And getting power out of an electric motor is really about getting the heat out.  And liquid cooling is just many times more effective than air cooling.

But we don't like leaks.  And so at EVTV we use AN fittings and hose ends with nylon braided hose. Properly assembled, these anodized aluminum hose ends will just never let go and they almost never leak.  So we've adopted the hardware used by race and custom car enthusiasts for transmission coolers, for use in our electric cars.  These are the highest quality components avialable.

This is a reproduction of our glycol heating system used in the Cadillac Escalade EXT Electric project.  We made about five different runs at this before getting it right.  It now works in stellar fashion giving us the original heating system that came with the vehicle.
Most modern vehicles use 195F water from the engine for heating and offer a simple inlet and outlet to the engine from the vehicle heat exchanger.  This extensive kti allows you to simulate that engine heat with a 5kW industrial strength electric heater.  Yes, it will decrease your range.  You may find that an acceptable trade on a four-mile drive at 10F ambient.  We certainly do.

AN-8 is nominally 1/2 inch hose equivalent while AN-6 corresponds to 3/8 hose.  The larger the hose, the more fluid flows per unit time.  And the more efficient your cooling will be.

 This is an excellent electric air conditioning 27cc high precision orbital scroll compressor available in two voltage ranges: 110-200v and 220-400v.  A permanent magnet brushless DC motor features an integral inverter/controller built into a very compact lightweight package.  But it is POWERFUL at up to 9 Nm in torque to produce 15700BTU/hr output at 6000 rpm.  It's also surprisingly quiet at 76 dB'

The control cable uses 12v input, a 12v enable signal, and a 12v 400Hz PWM signal to vary the speed (and cooling power) between 1000 and 6000 rpm.

It is absolutely TINY at 6.3 kilograms.

PTC HEATER for Electric Cars.

This is a PTC space heater for use in an electric car.  It operates nominally at 110v but we've run these as high as 200v in the past with great success and down to about 90v pack voltage.  It is also available in 220v and  360v versions.

Postive Temperature Coeffeicent heaters are very safe.  As temperature rises, so does resistance and so the current decreases.

 These are the coolant pumps used on the Azure Dynamics eTransit Connect.  They feature a brushless DC motor and integral inverter.  Powered by 12v, they have a PWM input allowing you to adjust output from zero to 30 liters per minute.

Voltage: 8.5 to 16 volts
Current at 12.5v : 6.5 amps
Free flow capacity: 30 liters per minute.
Capacity with 20ft head, 8.7 psi, 0.6 bar: 24 liters per minute

1/2 inch barbed ports.
Connecting plug components included

 This is a 12v water pump designed for EVs with 50 lpm flow rate - 25lpm at over 7 meters with plenty of power to cool any system.  

This is a very nearly identical version of the Pierburg CW50 pump from China at a lower price.  Currently used on Audi/VW.

 SILCONE RUBBER HEATING PAD BATTERY BOX HEATER

This 10 x 24 inch heating pad features a 3M adhesive backing and a 300 ohm etched foil flat heating element in a silicon rubber mat.  We've had it specially designed for heating battery boxes.

The heater features an internal thermocouple that allows heating up to the 25C/77F cutoff.  It will restart when the temperature falls to 15C or 59F.  This thermocouple is rated for 250volts maximum and will fail at voltages above that.  However, it fails ON and can be used on higher voltage systems with an external temperature controller.

This heating element is 300 ohms.  Heating in watts is a function of the voltage and current through the device.

This is a high quality high temperature DC12V submersible water pump.The pump can handle up to 80'C continuously. It can be submersed as long as liquid temperature is under 50'C. It's built by a brush-less motor so that it's quieter and lasts longer than a brush water pump. Also, it will not generate an 'electric spark' (noise) like a brushed type motor does so it's safer to use it when near a flammable gas. Ideal for solar heater, automobile, sprinkler system,irrigation, mobile home. It can be used to pump oil and gasoline as well.

Inline One-Way Non-return Checkvalve.  Male AN-8 fittings.  Flow direction clearly marked.
