SOLUTIONS FOR VOLTAGE DROP COMPENSATION
Voltage Drop Compensation Device (VDCD) by TEEMP is a parallel switching device with its own power supply.
Parallel switching makes it possible to operate in a reactive power supply mode and also simplifies the device installation.
The selected power supply is a storage subsystem based on ultracapacitors:
High discharge current, which is required to eliminate problems caused by power drops and interruptions;
Supercapacitors are much more reliable compared to lithium and lead-acid batteries, and are able to operate under frequent charge/discharge conditions;
The supercapacitors characteristics are less degraded over time;
Supercapacitors require lower operating costs.

SOLUTIONS FOR HYBRID TRANSPORT
Belkommunmash city bus featuring TEEMP hybrid system
CONFIRMED FUEL EFFICIENCY OF THE HYBRID BUS – 27.7%
MORE EFFICIENT COMPARED TO A STANDARD BUS EQUIPPED WITH INTERNAL COMBUSTION ENGINE
The hybrid system consists of at least 2 power supplies. The first and main power supply is ICE, while the auxiliary power plant is a supercapacitor energy storage unit (ESU). The TEEMP storage unit is charged by the ICE and also by braking energy.
The main purpose of the supercapacitor ESU is to reduce fuel consumption by regenerating braking energy for further using it in acceleration mode.

SUPERCAPACITORS FOR CARS WITH “MILD HYBRID”
Connection of the ultracapacitor to the car electric circuit
Mounting location of the supercapacitor module (under the passenger seat)
TATA Nano Car
Joint studies have been performed along with TATA Motors LTS (India) to use the mild-hybrid in cars to smooth the car battery loads as well as to accelerate the vehicle and regenerate its braking energy.
The use of a supercapacitor in connection with storage batteries made it possible to significantly reduce the power of the battery discharge during a peak load.
ТThe battery current was reduced from 6C to 1.5C.
According to TATA experts, the reduction in the storage battery discharge current results in a 2-3-fold increase in the battery life.
Besides, based on the energy consumption control system of the car the supercapacitor was “charged” from the car battery or using regenerative energy whenever the load capacity was low..
