Best batteries for hybrid cars in Nairobi Kenya

Hybrid car batteries work by storing and releasing electrical energy. When the car is in motion, the electric generator generates electricity that is stored in the battery. This stored energy is used to power the electric motor and recharge the battery when the car is idle or coasting. There are two different ways in which these batteries are charged that is; Through regenerative braking, Internal charging and external charging.

Regenerative braking is an important feature of hybrid cars. When a hybrid car brakes, the electric motor acts as a generator, converting the kinetic energy of the car into electrical energy. This electrical energy is then stored in the hybrid car battery, which can be used to power the electric motor when the car is idle or coasting. 

By converting the energy that would normally be lost during braking, regenerative braking helps to extend the lifespan of the hybrid car battery, improve fuel efficiency, and reduce emissions.

This is where the battery in a hybrid car is charged by the combustion engine on the car while its running by using excess energy of the engine. This charging system is controlled by a battery management system (BMS), which monitors the state of the battery and ensures that it is charged to the appropriate level.

Some hybrid cars can be plugged into an external power source to charge their battery, although this is not necessary for the car to function. Plugging in a hybrid car can help to extend its electric-only range and reduce fuel consumption, but it is not required as the car’s battery can be charged through regenerative braking and the gasoline engine.

Hybrid car batteries come in several types, with each type offering its own unique benefits and drawbacks. The most common types of hybrid car batteries include Nickel-Metal Hydride (NiMH) batteries, Lithium-Ion (Li-Ion) batteries, and Lead-Acid batteries.

NiMH batteries are the most commonly used hybrid car batteries. They are affordable and have a relatively long lifespan of 8-10 years. They are also relatively safe and reliable. However, they have a lower energy density than Li-Ion batteries, which makes them bulkier and heavier.

Li-Ion batteries are the most advanced and efficient type of hybrid car battery. They have a higher energy density than NiMH batteries, which means they can store more energy in a smaller size. They are also lighter and have a longer lifespan of 10-12 years. However, they are more expensive than NiMH batteries and require a more complex cooling system to prevent overheating.

Lead-Acid batteries are the oldest type of hybrid car battery. They are cheaper than NiMH and Li-Ion batteries and have a  lifespan of 3-4 years. However, they have a lower energy density than NiMH and Li-Ion batteries, which means they are bulkier and heavier. They are also less efficient and produce more emissions than other types of hybrid car batteries.
