that can increase capacity, reduce size, or lower the cost of the battery are going to prove highly
advantageous to the vehicle manufacturer, providing them with the prospect to add to their market

share. Consequently, new chemistry iterations and cell arrangements are being experimented with
on a constant basis.

EV manufacturers, supported by their battery suppliers and system integration partners, must
find ways through which they can outmaneuver their rivals. They need to develop energy storage
solutions that will lengthen the distance that their EVs can travel between recharges so that car
buyers are not troubled by range anxiety concerns. They also must explore design methodologies
that will keep vehicles’ part costs down as much as possible, thereby making their models more
attractive to car buyers and securing greater commercial uptake.

Increased cell densities mean more charge can be carried, and this will lead to longer vehicle
range. Likewise, support for faster charging will reduce the time spent at charging stations, thereby
providing users with greater convenience. In addition, the development of batteries that have
The Increasing prolonged working lifespans will mean that replacement costs can be avoided for longer, thus
lowering the total cost of ownership.

Importance of EV BATTERY SUPPLIER OBJECTIVES

Given how pivotal battery design and development are to the success of an EV model, battery
Battery Testing and suppliers are being placed under acute pressure. If they are to satisfy the expectations of the car

manufacturers they are engaged with, suppliers must:
