Voila! The Flux Capacitor has arrived in the Hyperdrive office.

This challenging assignment will utilise military cells usually designed for extreme applications, replacing the eight 12v lead acid batteries.

First things first, measuring the seats to fit additional cells.

RANGE EXTENDING ELECTRONICS
January 10 2014

The compromise between battery size and vehicle range remains a challenge for OEMs, but there is plenty of scope for innovative electronics to make a long lasting impression.

The range of pure electric vehicles is now up to around 70 miles typically and can vary significantly depending on ambient temperature, driving style and use of ancillary systems. The recently launched Tesla model S is exceptional with a marketed range of up to 265 miles from its large 85kWh battery pack.

Battery cell technology is improving and the commonly used lithium-ion chemistries cells now achieve up to 200 Watt hours per kilogram (Whr/kg). The automotive industry has a target to double this capability within five years, but even so these batteries will still only offer around one thirtieth of the energy density of petrol or diesel fuel, and this will continue to be restrictive.

Hyperdrive Innovation manufactures battery packs, incorporating their in-house developed sophisticated battery management systems (BMS), which automatically manage balancing between cells to optimise energy consumption and range. The BMS fits different cell chemistries and arrangements, controlling the charge and discharge of the individual cells, monitoring cell heath and communicating with the other vehicle systems via the controller area network (CAN). A separate Fuel Gauge product gives an immediate visual indication of the energy in each cell.

Nevertheless, the challenges associated with incorporating heavier and more expensive batteries to provide more energy storage for electric vehicles and solve range anxiety will continue to hold back the industry. Complementing the development of better batteries and BMS, range extended electric technologies have a major role to play in increasing the uptake of low carbon vehicles.

Not to be confused with parallel hybrids, range extended electric vehicles are designed to be run from the battery, but have a petrol or diesel generator to recharge as required. Electrical drive backed up by conventional liquid fuel reduces battery size and recharging times.

Hyperdrive Innovation has proven its range extended electric systems with modified petrol and diesel internal combustion engines, and these are now being deployed in new vehicles. The generator runs at its most efficient operating point and is turned off when it’s not needed, for example while sitting in traffic or when the battery charge reaches its upper threshold.

In high performance hybrid applications, such as racing cars, power density – high power and low weight – is the key requirement for maximum acceleration. Super capacitor technologies can make a dramatic impact on performance when used to recover and re-use energy that would normally be wasted.

Hyperdrive’s technology is attracting interest from outside of the passenger automotive sector and can be adapted for industrial, marine and defence applications. Current projects include the development of new sensors in a drive by wire system on a combine harvester and the design and build of complete hybrid power trains for an unmanned marine vessel. The approach to developing an integrated electric drive train will usually necessitate new designs for electric circuits, firmware and battery packs.

The potential for better vehicle management to achieve efficiency gains should also not be underestimated, particularly for commercial fleet managers. Hyperdrive’s H-Logger is a vehicle data logger and telemetry system that enables any signal on the vehicle CAN to be recorded on board and sent via the mobile phone network to a secure server for storage. This has proved extremely effective in trials of new vehicles where real time data on vehicle location and fuel consumption can be accessed and monitored on-line at any time.
